2. Check that the connected spectrometer is recognized. If not, click to "Scan USB"

3. Apply an optical input signal to the fiber input. Increase the integration time until the spectrum is

displayed. A right click into the data display area zooms in the intensity axis to it's best fit to the spectrum.

Note

If you are using a CCS200 broadband spectrometer and a continuous spectrum (e.g. of a white light lamp) shall be measured, please note the following recommendation:

Due to the eccentricity between the fiber core and the ferrule of the delivered FG200UCC MMF and the geometry of the input slit of the spectrometer, the displayed spectral intensity may vary when the SMA connector of the fiber is rotated within the input receptacle of the CCS200. Please find the maximum intensity by rotation and then fix the fiber connector with the lock bush. This ensures best measurement results.

The remainder of this manual is devoted to the setup procedure and features of the CCS Series Spectrometer.

Movable Markers

4.1.5 Marker

The OSA software offers two types of markers - movable and fixed.

4.1.5.1 Movable Markers

Movable Markers

The movable markers can be used to inspect the value of the data at different positions, to change the displayed area of the graph (see zooming the

vertical axis and zooming the horizontal axis), or

to place fixed markers. There are four movable markers: two line

markers - Markers 1 and 2 - and two level markers - Markers 3 and 4. Enable and disable them by pressing the respective buttons in the “Marker” menu. The markers can also be enabled and disabled by pressing Ctrl and their respective number on the keyboard.

As soon as at least one movable marker is enabled, the marker panel appears to the right of the spectrum display. It contains detailed information:

for line markers: wavelength and corresponding intensity value of the active trace for each marker and (selectable) the difference or quotient of their wavelengths

for level markers: intensity value level and

(selectable) the difference or quotient of their intensity levels on the primary axis.

difference / quotient are displayed only if both appropriate markers are enabled.

Moving

Place the mouse cursor over the marker, the mouse pointer changes to . Press and hold the left mouse button down to drag the movable marker to the desired position.The position of the movable markers can also be changed by clicking on the number of a marker to move in the cursor panel. This brings up a dialog to set the position of the marker numerically:

For the actual marker, either it's absolute position or it's position relative to the the paired marker can be entered numerically.

4 Operating Instruction

Marker Options

Clicking to Marker Options, some additional marker features can be configured:

Both the line and level markers can be locked / unlocked. When locking a marker pair, their distance will remain constant when moving one of them. By clicking the pad lock icon, the lock status can be toggled.

The relation between the 2 markers can be displayed as their quotient (ratio) or difference.

"Decimals Displayed" allows to select 1 to 11 decimals or "auto".

Automated Peak Search functions The Peak Search and Search Left (Right) buttons allow to quickly set line marker #1 to a peak.

Note : Prior to using this button, the peak search criteria, such as search wavelength range,

threshold and minimum peak height, must be set in the menu Setup -> Peak Track! Press Peak Search to find the highest peak within the selected wavelength range. When pressing

Peak Search repeatedly, the line marker #1 will jump to the next lower peak, after finding the last peak, it jumps back to highest. Search Left and Search Right buttons move the cursor to the next adjacent peak in the stated direction.

For each peak position, the wavelength and correlated intensity will be shown numerically as shown in the figure Movable Markers.

CCS Series Spectrometer

4.1.5.2 Fixed Markers

The Thorlabs OSA software can handle up to 2048 fixed markers. A fixed marker has a fixed position, is connected to a single trace (not necessarily the active trace) and will track the intensity value at the given wavelength. The fixed markers are identified by a number, starting with 0 for the first fixed marker added. The levels of the fixed markers can be tracked in a time series analysis.

Each fixed marker added is shown in the spectrum display as a triangle with its identifying number above it. The location of the triangle is determined by the position of the fixed marker and the value of the connected trace at the given position.

The values of the fixed markers and their positions can be stored to file or copied to clip board for processing in other software.

Adding

In the currently active trace, a fixed marker can be derived from line marker 1 - just press the button “Add Fixed”. The fixed marker is added to the trace, and below the trace a table comes up with detailed numerical characteristics of the fixed markers:

Table Columns:

Marker number - the number displayed in the diagram above the appropriate fixed marker. The first marker (number 0) is the reference marker.

Trace - the correlated trace character is displayed (not necessarily the active trace!)

Position - X axis position, at which the marker is located. The header states the unit, as set up in the settings bar.

Level - the level of the trace at the marker's position. The header shows the unit, depending on the current trace function.

Δ Position - the distance to the position of the previous marker, in the same unit as column Position

Offset - the distance to the reference marker (# 0), in the same unit as column Position.

Δ Level - level difference between the actual and the reference marker, in the same unit as column Level

4 Operating Instruction

Remove Fixed

Any fixed marker can be removed individually by moving line marker 1 to the position of the fixed marker and pressing the button “Remove Fixed”. Alternatively, right click in the table to the line of the fixed marker that shall be removed and select "Remove Marker" from the table options.

Clear Fixed

This button removes all fixed markers from the trace.

Mark Peaks

Pressing the button “Mark Peaks” will add one fixed marker to each automatically detected peak that corresponds to the peak finding settings in the currently active trace. The first marker will be added to the highest peak in the spectrum, the second marker to the second highest peak, etc.

Note: This will add fixed markers to the found peaks in the currently active spectrum; the positions

of these markers will not change until they are removed.

Table Options Menues

The menu "Save Table to File" opens a dialog to store the fixed marker table in CSV format. This can be done also by right clicking to the table and selecting “Save Table to File”.

A previously saved table can be opened using the "Load Table from File" button.

The very right button copies the table to the clipboard, this way the table can

be quickly pasted to other software (e.g. EXCEL). This can be done also by right clicking to the table and selecting "Copy Table".

The columns of the table to be displayed can be selected from the Select

Columns button:

Quick access to marker table

4.1.6 Analysis

Note

The grayed-out features are available only for if the active device is an OSA20x spectrometer. Color Analysis button is shown only with amplitude correction enabled.

4.1.6.1 Peak Track Analysis

In Peak Track analysis mode, the position, amplitude, and width of peaks in the spectrum can be tracked over time.

As long as the Track Peak mode is active, the Track Peak analysis area will be displayed below the data display. Here, a data table shows information about the peaks and as well as a small toolbox with the settings that used to find the peaks. It is also possible to select which columns can be displayed in the data table by clicking on the button “Select Columns”.

4 Operating Instruction

The parameters used to find the peaks are:

Threshold: Only data points with intensity above this level will be used when searching for peaks. Threshold can be entered manually or retrieved from a level marker (click to )

Min Peak Height: Only peaks that have a peak-to-base ratio of at least this value will be found.

Note The Minimum Peak Height affects the reported width of the peaks - it's the width of the

peak at this level from the maximum value. For example, a value of 3 dB here will give the FWHM of the peak and a value of 6 dB here will give the width of the peak and a quarter of the maximum value.

Search Range: (Wavelength / Wave number / Frequency): Limits the x-axis range in which the search for peaks is performed. It can be entered numerically, retrieved from line markers (

) or from the currently displayed range ( ).

In Track Peak mode, the currently active spectrum is checked for peaks upon the collection of a new spectrum from the instrument. The peaks are by default sorted in order of decreasing intensity. The sorting can be changed by left clicking to the parameter. In above screenshot the peaks can be sorted by increasing / decreasing wavelength (toggling).

Right clicking in the data table brings up a dialog to:

add a fixed marker at the highlighted peak;

Move movable markers to this peak:

Line marker 1 will be set to the peak wavelength Line marker 2 displaced from peak wavelength for + half the FWHM Level marker 3 to the peak level Level marker 4 to the FWHM level

increase / decrease font size in the table

copy the table - it can be pasted then directly to other applications like Microsoft EXCEL

save the table to file (CSV file with selectable separator)

The peaks found in Track Peak mode can be tracked over time in a time series analysis (see the Long Term Tests) if the Track Peak analysis mode is started before the time series analysis is

started. Notice that since the peaks are ordered by decreasing intensity, they can be rearranged if the relative intensity of the peaks in the spectrum is changed.

If no peaks are found in the Track Peak mode, check the settings for the threshold and min-peak height to make sure that the expected peaks in the spectrum are higher than this. The settings can be changed either in the Setup Dialog or directly in the Options Control box found to the right of the data table in the Peak Track Analysis area.

4.1.6.2 Color Analysis

The Color Analysis performs a color analysis of the currently active trace. The analysis calculates the chromaticity coordinates (x, y, and z) and the main wavelength in the spectrum.

The Thorlabs OSA software calculates the correlation between the collected spectrum and the three color matching functions x(λ), y(λ), and z(λ) defined from the CIE 1931 2° standard observer to obtain the tri-stimulus values X, Y, and Z. These are then normalized to obtain the chromaticity coordinates x, y, and z.

The calculated chromaticity coordinates x and y are displayed in the CIE 1931 color space chromaticity diagram as a dark circle as well as displayed numerically next to the diagram.

The dominant wavelength is calculated as the interception between the straight line from the white point (1/3, 1/3) through the calculated chromaticity point (x, y) and the edge of the chromaticity diagram.

4 Operating Instruction

The purity is calculated as the portion of the distance from the white point (1/3, 1/3) to the edge of the chromaticity diagram that the distance from the white point (1/3, 1/3) to the calculated chromaticity represents. A purity of 100% represents a point on the edge of the chromaticity diagram, i.e. a pure color, and a purity of 0% represents a mix of all colors, i.e. the white point itself.

The Correlated Color Temperature (CCT) can be calculated for a light source that is close enough to the Planckian locus in the 1960 UCS. The CCT is calculated by converting the calculated chromaticity point (x, y) into a point in the CIE 1960 color space (u, v) and finding the closest Planckian locus. If the distance to the closest Planckian locus (Δu,v) is larger than 0.05 then a temperature of -1 Kelvin is returned as an error code.

The threshold option makes it possible to ignore data points in the spectrum with low intensity; this can be useful e.g. if the spectrum is very noisy. For easy handling, the threshold can be defined by a level marker.

Resample Data

Change the sample points in the current trace. Brings up a dialog to select the resampling factor. The resampling factor is the desired length of the trace divided by the current length of the trace.

Example:

- Selecting a resampling factor of 0.5 reduces the length of the trace by a factor of two

- A resampling factor of 4.0 increases the length of the trace by a factor of four.

The resampling is performed using a quintic spline interpolation to make the resampled trace as similar to the original trace as possible.

4.1.8 Setup

Click to Setup button in main menu. A dialog window with 4 tabs comes up:

Active Device

Display

Peak Track

Reset

4.1.8.1 Tab Active Device

4 Operating Instruction

The active device tab shows information on the active instrument and has 3 sub-tabs. Common: Set integration time and trigger mode. The integration time can be set between 10µs

and 60 s. The trigger source can be internal (software trigger) or external via the SMB connector.

Amplitude correction:

Note

The amplitude correction will work properly only if the CCS spectrometer was factory calibrated for amplitude correction!

The factory amplitude correction can be carried out only for wavelengths > 380 nm. With enabled amplitude correction, the intensity is displayed "calibrated", i.e., taking into account

the wavelength dependent responsivity of the CCS spectrometer. This leads to an increase of the noise at wavelengths with lower responsivity, as not only the wanted signal is amplified, but also the noise. In the setup panels this increase of noise is stated as "Noise amplification", which is in fact the ratio of the max. and min. responsivity (in dB) within the given wavelength range. The amplitude correction can be configured in two setup modes: Wavelength Range (recommended for accurate intensity results in a give wavelength range) and Noise amplification (recommended if weak intensities are measured and a minimum noise interference is required). The two examples below explain both modes in detail.

CCS Series Spectrometer

Open in the Setup Menu the tab "Active Device" and then the sub-tab "Amplitude correction", select Setup Mode "Noise Amplification":

Enter the desired center wavelength and the allowed noise amplification; the OSA software calculates the resulting min. and max. wavelengths. The screenshots below illustrate how enabling the amplitude correction affects the spectrum display of a.m. cold white LED with above settings. For better visualization, a line marker is inserted at the center wavelength range:

CCS Series Spectrometer

Wavelength Calibration

The sensor of a CCS spectrometer is CCD line. Depending on the wavelength, the incident to the spectrometer light is directed to a certain pixel of the CCD line. Each CCS spectrometer is factory calibrated, using a calibration source with well-known spectral lines. The factory calibration is saved to the internal non-volatile memory and defines the exact wavelength for a number of pixels. Between these calibration points, the wavelength is interpolated.

In certain cases a more detailed user calibration, based on an available calibrated spectral source, might be desired. The user can then replace the factory calibration with a user calibration, consisting of a min. of 4 and a max. of 10 individual calibration points.

First of all, apply the individual spectral source to the CCS spectrometer input and adjust the integration time in such way that maximum intensities are displayed without entering saturation.

Then Setup -> tab Active Device -> subtab Wavelength Calibration:

The small display can be easily zoomed by dragging the desired zoom area with left mouse button hold pressed.

When release the left mouse button, the display appears zoomed. Move the mouse to the peak and press right mouse button. The peak will be marked now by a blue cross and the related pixel number will be displayed in the Calibration Point box:

4 Operating Instruction

Enter the corresponding wavelength and press Add button - the calibration point will be added to the table. Repeat these operations until at least 4 calibrations points are entered.

Any calibration point in the table can be edited by following the steps below:

- mark it in the table

- the data will appear in the input box.

- correct the wavelength

- press Update - the table will be updated.

After the calibration table is complete, press Save. The user calibration points will be stored to the CCS spectrometer. From now on, the wavelength calibration can be switched between Factory and User Calibration by checking the box "Enable User Wavelength Calibration"

4.3 Trace Controls

The acquired spectra are displayed in “traces.” The Thorlabs OSA software can handle up to 26 traces labeled from “A” to “Z”; the most left trace is always A followed by B, etc. The controls for the traces are located below the settings bar. The color of each trace is shown as background of the trace letter; traces which are not displayed in the data display area are shown in a faded out color. To the right of the trace letter (“A”, “B”, etc.) the update option for the trace is displayed, determining what will happen with the trace during the next data acquisition.

Additionally, a legend can be displayed showing for all not hidden traces their color and a selectable text. The legend can be placed to any location within the spectrum display. The initial trace settings (number of traces and their appearance) at program start are configured in the Setup

-> Display menu. After program start, trace A is set as active and will be updated with each new

data acquisition. Click to the trace header to open the Trace properties menu:

Show Toggle to show / hide the trace. Additionally, all other traces can be shown or hidden at one click. The trace header remains when a trace is hidden.

Set as Active Setting a trace active enables further operations (saving, loading, etc.).

Change Color Change the trace color

Move to Secondary Axis By default, all traces have a common Y

axis. This may become inconvenient, particularly, if one trace displays e.g. intensity (max =1.0), and another trace a ratio that may reach thousands of units. In such case, the software automatically zooms the Y axis to the trace with the widest range, as a consequence the intensity trace becomes almost a flat line. In such case, a trace can be moved to secondary axis, that appears to the right of the spectrum display area. The primary and the secondary Y axes can be zoomed independently.

Write Set a trace to Write in order to update it with the next acquired spectrum.

Average / Average and Stop The number of acquisitions to be average can be set. The averaging method is rolling average (over the last "n" acquisitions). There are several presets from 5 to 200 averages, other values can be entered by pressing the Custom

button. The "Average and Stop" terminates the spectrum display update after finishing the given number of averages. Please note that the spectrum acquisition however continues. To display recent acquisitions, uncheck the "Average and Stop" option.

Fix Fixes the content of the current trace, i.e., it will not be overwritten with next acquisition.

Min (Max) Hold If the spectrum intensity changes with a new data acquisition, this function holds

the minimum (maximum) intensity value.

4 Operating Instruction

OSA software terminates with error message "Software cannot be installed"

Check if you have administrator privileges on your computer

Make sure that the operating system is min. Windows Vista or up. See also Requirements.

OSA software cannot find any devices but the virtual devices :

Check if VISA runtime 5.1 or higher is installed.

Make sure that the connected device is made by Thorlabs.

Try to connect the device to another USB port.

"Found New Hardware Wizard" finishes with the error "the wizard cannot find the necessary software":

This error occurs when the installer cannot find OSA software installed on your system.

Install OSA software.

Be sure that your device is configured as a VISA device.

Check if VISA runtime 5.1 or higher is installed on your system.

The Intensity of the measured signal does not increase linearly with the integration time:

The CCD array applies an electronic shutter function, if integration times below 4 ms are used. In that case the pixels are sequentially recharged, until the time to the next CCD readout matches the wanted integration time. Unfortunately the manufacturer of the CCD does not guarantee this recharging/resetting of the array to be 100% effective. Therefore it cannot be guaranteed that all photons are ignored, before the actual integration time starts. This might cause peak heights to in- or decrease to a higher degree than the integration time was changed.

If you want to make relative comparisons of signal heights or areas beneath the curve, try using integration times above 4 ms and use the dark current correction

7.3 Tutorial

In this section some complementary information is given.

Spectrum File Formats

The Thorlabs OSA software uses a variety of file formats in order to record measurement results.

*.spf2: This is the internal file format to save and load spectrum files from one or more traces. The file header consists of information about the used spectrometer, it's s/n, acquisition settings and trace properties.

*.spc: This file format is a 2D graphic file format, invented by Galactic Industries in 1986 for storage of a variety of different types of data taken from laboratory analytical instrumentation, primarily spectral and chromatographic (trace) data. The SPC format is capable of storing single or multiple arrays and is designed to be general enough to contain most types and styles of data storage such as even X spaced, non-even X spaced, variable record sizes, and 16 or 32 bit data representation. It is also capable of storing arbitrarily large descriptor blocks.

*.jdx: The JCAMP-DX is a commonly used file format for infrared, NMR (nuclear magnetic resonance), and mass spectrometry data introduced by the Joint Committee on Atomic and Molecular Physical Data (JCAMP). More information can be found at http://www.jcamp-dx.org/.

*.csv: The standard comma separated variables file type. It is used to save a single trace. When saving, the separator can be selected to semicolon, comma or tab. Thorlabs OSA software CSV export file has a header of 34 lines with information on the used spectrometer, it's settings, data on the graph and 2 lines for entered manually individual comments. The header is followed by 3648 lines (equal to the 3648 pixels of the CCS spectrometer CCD line) of 2 columns: The first column states the wavelength in [nm], the second the relative intensity.

*.txt: When exporting the active trace, the text file format can be used. A separator (semicolon, comma or tab) must be selected. The exported file contains only the data of the spectra: The first column states the wavelength in [nm], the second the relative intensity.

*.mat: A trace can be saved as a Matlab v.5 file. Level 5 MAT-Files include additional support for multidimensional numeric arrays, character arrays, cell arrays, sparse arrays, objects, and structures.

Image File Formats

A trace can be saved from Thorlabs OSA software in *.bmp, *.png, and *.jpg formats.

Virtual Devices

In order to demonstrate the OSA software functionality even without a spectrometer connected, a Virtual Device can be activated. Virtual devices just simulate a spectrometer. Add a virtual device by selecting "Devices" in the Sweep menu, then click the button " Virtual":

A list of available devices comes up:

Select one, the click "Add". The virtual device is listed now:

Select it, then click "View Info" to display it's properties:

CCS Series Spectrometer

"Settings" file format

The settings of the current spectrum acquisition, that include the spectrum display settings and the settings of the active spectrometer, can be saved as a *.sml file. The file format is XML V 1.0, and the extension was chosen to sml for easy identification.

The file extension is not associated with the SMILE software tool by Simulistic, nor with Single

Markup Language.

Wavelength, Frequency, photon energy and wave number

Photons can be characterized by their frequency, energy, wavelength and wave number, where the wavelength and the wave number depend on the propagation speed in the given medium.

Energy and frequency are related by the equation

with h - Planck constant = 4.13566733 x 10

- frequency

-15

eVs

c - light propagation speed in vacuum = 2.99792458 x 10 8 m/s

- wavelength in vacuum

Wavelength and frequency are correlated by the formula

with

- wavelength in vacuum

vac

- light propagation speed in vacuum = 2.99792458 x 10 8 m/s

vac

- frequency

If the light propagates in a different medium than vacuum, it's propagation speed decreases for a factor called the refraction index. In such case, the wavelength is calculated to

where n is the refraction index. In air, the refraction index is 1.000293, in water - 1.333 The wave number is the spatial frequency of a wave, either in cycles per distance or radians per

unit distance. It can be described as the number of waves that exist over a specified distance. In spectroscopy usually the wave number is given per centimeter (cm -1) and calculated by the formula

7 Appendix

Transmission and Absorbance

Transmission T (aka transmittance) is the fraction of incident light that passes through a sample, it is calculated as

with I

- intensity at the output of the sample

out

- incident to the sample intensity

Transmittance is stated in %. Absorbance A (aka Optical Density OD) is the logarithmic ratio of the intensity, incident to a

sample, to the intensity, passing through the sample:

with I

- intensity at the output of the sample

out

- incident to the sample intensity

T - transmittance

Absorbance is stated in "absorption units", abbreviated "A.U." or "AU".

7.8 Thorlabs 'End of Life' Policy (WEEE)

As required by the WEEE (Waste Electrical and Electronic Equipment Directive) of the European Community and the corresponding national laws, Thorlabs offers all end users in the EC the possibility to return “end of life” units without incurring disposal charges.

This offer is valid for Thorlabs electrical and electronic equipment

sold after August 13th 2005

marked correspondingly with the crossed out “wheelie bin” logo (see figure below)

sold to a company or institute within the EC

currently owned by a company or institute within the EC

still complete, not disassembled and not contaminated

As the WEEE directive applies to self contained operational electrical and electronic products, this “end of life” take back service does not refer to other Thorlabs products, such as

pure OEM products, that means assemblies to be built into a unit by the user (e. g. OEM laser driver cards)

components

mechanics and optics

left over parts of units disassembled by the user (PCB’s, housings etc.).

Waste treatment on your own responsibility

If you do not return an “end of life” unit to Thorlabs, you must hand it to a company specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site.

WEEE Number (Germany) : DE97581288

Ecological background

It is well known that waste treatment pollutes the environment by releasing toxic products during decomposition. The aim of the European RoHS Directive is to reduce the content of toxic substances in electronic products in the future.

The intent of the WEEE Directive is to enforce the recycling of WEEE. A controlled recycling of end-of-life products will thereby avoid negative impacts on the environment.
