1: Introduction

About SpectraSuite

SpectraSuite is the latest generation of operating software for all Ocean Optics spectrometers. It is a
completely modular, Java-based spectroscopy software platform that operates on Windows, Macintosh
and Linux operating systems. The software can control any Ocean Optics USB spectrometer and device,
as well as any other manufacturer’s USB instrumentation using the appropriate drivers.

SpectraSuite is a user-customizable, advanced acquisition and display program that provides a real-time
interface to a variety of signal-processing functions. With SpectraSuite, you have the ability to perform
spectroscopic measurements (such as absorbance, reflectance, and emission), control all system
parameters, collect and display data in real time, and perform reference monitoring and time acquisition
experiments. Consult the SpectraSuite manual for hardware requirements when using SpectraSuite (see

Product-Related Documentation

).

Sampling System Overview

How Sampling Work s

Ocean Optics components function in a sampling system as follows:

1. The user stores reference and dark measurements to correct for instrument response variables.

2. The light transmits through an optical fiber to the sample.

3. The light interacts with the sample.

4. Another optical fiber collects and transmits the result of the interaction to the spectrometer.

5. The spectrometer measures the amount of light and transforms the data collected by the

spectrometer into digital information.

6. The spectrometer passes the sample information to OOI software.

7. OOI software compares the sample to the reference measurement and displays processed spectral

information.

Modular Sampling Accessories

Ocean Optics offers a complete line of spectroscopic accessories for use with Apex. Most of our
spectroscopic accessories have SMA connectors for application flexibility. Accordingly, changing the
sampling system components is as easy as unscrewing a connector and replacing an accessory.

Installing Apex

Overview

You must install the operating software application prior to connecting the Apex Spectrom eter to the
computer. The Ocean Optics spectrometer operating software installs the drivers required for the Apex
spectrometer installation. If you do not install the software first, the system will not properly recognize
the Apex.

If you have already connected the Apex to the computer prior to installing the operating software, consult

Chapter 3: Troubleshooting

for information on correcting a corrupt Apex installation.

Apex Installation

This section contains instructions for connecting the Apex in USB mode. To connect the Apex to a
computer via the USB port, the computer must be running a Windows 2000/XP/7 (32- or 64-bit), Mac OS
X or Linux operating system.

►

Procedure

Follow the steps below to connect the Apex to a computer via the USB port:

1. Install the spectrometer operating software on the destination computer.

2. Locate the USB cable (USB-CBL-1) provided with the Apex.

3. Insert the square end of the cable into the side of the Apex.

4. Insert the rectangular end of the cable into the USB port of the PC.

If you installed the spectrometer operating software prior to connecting the Apex, the software installs the
Apex drivers. If the drivers do not successfully install (or if you connected the Apex to the computer
before installing the software), consult Chapter 3: Troubleshooting

.

Configuring Apex in SpectraSuite

The Apex can be used with SpectraSuite operating software when connected to the USB port.
If you have followed the previous steps and started SpectraSuite, the spectrometer is already acquiring

data. Even with no light in the spectrometer, there should be a dynamic trace displayed in the bottom of
the graph. If you allow light into the spectrometer, the graph trace should rise with increasing light
intensity. This means the software and hardware are correctly installed.

Note

If the INF directory is not visible, you must disable the Hide System Files and Folders

and Hide File Extensions for Known File Types options in Windows Folder Options.

Access Windows Folder Options from Windows Explorer, under the Tools | Folder

Options menu selection.

3. Delete the OOI_USB.INF in the INF directory. If your computer is running either the Windows

2000 or XP operating system, you must also delete the OOI_USB.PNF file in the INF directory.

4. Navigate to the Windows | System32 | Drivers directory.

5. Delete the EZUSB.SYS file.

6. Reinstall your Ocean Optics application and reboot the system when prompted.

7. Plug in the USB device.

The system is now able to locate and install the correct drivers for the USB device.

Mac Operating Systems

Since there are no device files for the Apex Spectrometer in a Mac operating system, you should not
encounter any problems if you installed the spectrometer before the operating software.

Linux Operating Systems

For Linux operating systems, all you need to do is install the softwar e, then unplug and replug in the
spectrometer. Technically, the driver files for Linux simply give nonprivileged users permission to use
newly connected hardware. There isn’t any long-term harm to plugging in the device before installing the
software.

Appendix A

Calibrating the Wavelength of

Apex

Overview

This appendix describes how to calibrate the wavelength of your spectrometer. Though each spectrometer
is calibrated before it leaves Ocean Optics, the wavelength for all spectrometers will drift slightly as a
function of time and environmental conditions. Ocean Optics recommends periodically recalibrating the
Apex.

About Wavelength Calibration

You are going to be solving the following equation, which shows that the relationship between pixel
number and wavelength is a third-order polynom ial:

λ

= I + C1 p + C2 p2 + C3 p

p

Where:

λ

= the wavelength of pixel p

I = the wavelength of pixel 0

= the first coefficient (nm/pixel)

C

1

= the second coefficient (nm/pixel2)

C

2

= the third coefficient (nm/pixel3)

C

3

You will be calculating the value for I and the three Cs.

892-00000-000-02-201302 5

A: Calibrating the Wavelength of the Apex

Calibrating the Spectrometer

Preparing for Calibration

To recalibrate the wavelength of your spectrometer, you need the following components:

• A light source capable of producing spectral lines

Note

Ocean Optics’ HG-1 Mercury-Argon lamp is ideal for recalibration for wavelengths up to

922 nm. For wavelengths above 922 nm, we recommend the XE-1 Xenon Light Source.

If you do not have an HG-1, you need a light source that produces several (at least 4-6)

spectral lines in the wavelength region of your spectrometer.

• An Apex spectrometer

• An optical fiber (for spectrometers without a built-in slit, a 50-

• A spreadsheet program (Excel or Quattro Pro, for example) or a calculator that performs third-

order linear regressions

µm fiber works best)

Note

If you are using Microsoft Excel, choose Tools | Add-Ins and check AnalysisToolPak

and AnalysisTookPak-VBA.

Calibrating the Wavelength of the Spectrometer

► Procedure

Perform the steps below to calibrate the wavelength of the spectrometer:

1. Place the spectrometer operating software into Scope mode and take a spectrum of your light
source. Adjust the integration time (or the A/D conversion frequency) until there are several
peaks on the screen that are not off-scale.

2. Move the cursor to one of the peaks and position the cursor so that it is at the point of maximum
intensity.

3. Record the pixel number that is displayed in the status bar or legend (located beneath the graph).
Repeat this step for all of the peaks in your spectrum.

4. Use the spreadsheet program or calculator to create a table like the one shown in the following
figure. In the first column, place the exact or true wavelength of the spectral lines that you used.

In the second column of this worksheet, place the observed pixel number. In the third column,
calculate the pixel number squared, and in the fourth column, calculate the pixel number cubed.

7. Record the Intercept, as well as the First, Second, and Third Coefficients. Additionally, look at
the value for R squared. It should be very close to 1. If not, you have most likely assigned one of
your wavelengths incorrectly.

Keep these values at hand.

Saving the New Calibration Coefficients

Ocean Optics programs wavelength calibration coefficients unique to each Apex onto an EEPROM
memory chip in the Apex.

You can overwrite old calibration coefficients on the EEPROM if you are using SpectraSuite software.

►

Procedure

To save wavelength calibration coefficients using the USB mode, perform the following steps:

1. Ensure that the Apex is connected to the PC.

2. Open SpectraSuite softwar e .

3. Select Spectrometer | Spectrometer Features from the menu, or right-click on the Apex in the
Data Sources pane and select Spectrometer Features.

4. Select the Waveleng th tab.

5. Enter the new values acquired in Steps 5 and 6 of the Calibrating the Wavelength of the

Spectrometer section in this appendix.

6. Click Save to Spectrometer.

The new wavelength calibration coefficients are now loaded onto the EEPROM memory chip on the
Apex.
