Introduction
Product Overview
Jaz is a community of stackable, modular and autonomous component modules that combine to create a
community of smart sensing instruments that is unfettered by the limits of traditional optical sensing
instrumentation: a powerful microprocessor and onboard display eliminate the need for a PC; stackable,
autonomous instrument modules allow users to customize the system to their changing application needs;
and Ethernet connectivity plus SD card data storage capability facilitate remote operation.
Jaz is built on a platform that expands to include a light source, rechargeable lithium-ion battery and up to
8 spectrometer modules to make Jaz the first analytical instrument easily adaptable for the field, lab or
process environment. Jaz can also connect to a computer via the USB port. When connected through a
USB 2.0 or 1.1, the spectrometer draws power from the host computer. Jaz, like all USB devices, can be
controlled by our SpectraSuite software, a completely modular, Java-based spectroscopy software
platform that operates on Windows, Macintosh and Linux operating systems.
Jaz is extremely adaptable. It can be powered via battery, USB connection, over the Ethernet, or from a
power outlet. The Jaz display can be rotated 180 degrees in either direction and the faceplate itself can be
specified for either orientation. You can order the specific modules needed for your particular application
to be built in the Jaz stack, making Jaz a uniquely customizable scientific instrument and eliminating the
cost of unnecessary components.

EEPROM Utilization
An EEPROM memory chip in each JAZ-S spectrometer module contains wavelength calibration
coefficients, linearity coefficients, and a serial number unique to each individual spectrometer module.
The SpectraSuite software application reads these values directly from the spectrometer, enabling the
ability to “hot-swap” spectrometers between computers without entering the spectrometer coefficients
manually on each computer.
About SpectraSuite
Although Jaz is unique in that it can perform a number of spectroscopy measurements and display results
right on its display screen, SpectraSuite spectrometer operating software is also available to enhance Jaz’s
functionality. 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.

1: Introduction
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 Works
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 from the light source 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 SpectraSuite.
7.SpectraSuite compares the sample to the reference measurement and displays processed spectral
information.
Interface Options
Jaz is field-portable and can collect data as a free-standing unit from the battery embedded in the stack.
The Jaz stack also has both USB and Ethernet port connectors, enabling you to connect the spectrometer
to a computer via a USB port or to the network via a connection from the Ethernet port to a Power Over
Ethernet (POE) bridge or a switch to the network (e.g., a network hub). Your Jaz stack receives power
from either connection, and both connections enable Jaz to be recognized by SpectraSuite software.
Shipment Components
Jaz is a scalable system, allowing you to design the instrument most appropriate for your application.
However, a typical Jaz system could consist of the following components:

Chapter 4
Operating the JAZ-PX Module
JAZ- PX Module Overview
The Jaz PX lamp is a pulsed, short arc xenon lamp for UV-VIS applications such as absorbance,
bioreflectance, fluorescence and phosphorescence. The lamp has a specified pulse frequency of 200 Hz
(maximum 500 Hz) and spectral response from 190 – 1100 nm.
WARNING
The PX-2 produces ultraviolet radiation. Direct eye contact can cause permanent
eye damage. Always wear safety eyewear, and never look directly into the light
source.
The JAZ-PX module operates in both free running and triggered modes, allowing its pulses to coordinate
with other devices in the stack. The module contains an SMA connector to couple to other Ocean Optics
accessories such as optical fibers, cuvette holders, probes, etc. (see Additional Equipment Available
).
The JAZ-PX is ideal for field applications such as bioreflectance that require a high-intensity, low-power
light source. In fact, no external power supply is required to operate the JAZ-PX module. When used in
battery power mode, the lamp will operate for approximately 3 hours. An additional external power
supply is avialable through an optional 50 Watt-hour jaz battery extender (see Additional Equipment
Available).
For JAZ-PX module specifications, refer to Appendix B: Specifications.
Caution
The spectrometer module is especially sensitive to heating, so you should be aware
of the effects of heating on spectrometer modules when setting up an experiment,
particularly when using the JAZ-PX module. Since the JAZ-PX does not include a
fan and the Jaz metal housing has high thermal conductivity, heat generated by the
JAZ-PX will be conducted to other modules in the stack.
These effects are most prevalent in applications with long term, continuous
operation of the JAZ-PX at moderate to high flash rates. For short-duration
experiments, these thermal effects are not as prominent.Most significantly, heating
a spectrometer module will cause that spectrometer’s baseline (the measured
intensity when it is not exposed to light) to drift downwards.

Menu ItemDescription
IntensityControls the discharge voltage (and thus the flash intensity) of the lamp. Select
400-600V. On battery power, the intensity is restricted to 400V.
Number of FlashesSets the number of times that the lamp should flash after detecting a trigger event.
Holdoff TimeSpecifies how long the timing generator should wait after detecting a trigger event
before beginning to flash at the rate specified by the Flash Rate parameter.
Timing ControlsControls used to set the timing behavior of the JAZ-PX module.
Force TriggerAn emulated trigger signal that can be used to force trigger events on the JAZ-PX
module at any time. Forcing a trigger causes a trigger event with the same
behavior as if the device detected a stack trigger. Force Trigger will not have any
effect when the device is in Free Running mode, but it is not masked by turning
Trigger Enable off.
Timing ResetDoes not reset the timing parameters themselves. Instead, it resets the state of the
counters keeping track of timing in the hardware. This can be useful to “escape”
from long flash periods or large values set in the Number of Flashes parameter.
Free RunningPuts the device into Free Running mode. In this mode, the timing generator simply
flashes the lamp at the rate that is specified by the Flash Rate parameter and
ignores trigger events.
Run ForeverWhen enabled, the timing generator will enter Run Forever mode. In this mode, it
will ignore the Number of Flashes parameter setting and continue flashing forever
once it has received a trigger event. It will re-sync to any trigger events that are
detected during that time.
Output EnableWhen disabled, the lamp will not flash. When set to 1, the lamp will flash as
normal.
Trigger EnableWhen enabled, the timing generator will not detect trigger events that are
generated by the stack trigger. It will still detect timing events that are generated by
the forced trigger.
Advanced SettingsProvides the advanced capability to set parameters and controls directly on the
device, bypassing the Jaz menus. It also contains the power management menu.
Write RegisterAllows you to write values directly to the control registers of the JAZ-PX module.
Read RegisterAllows you to write values directly to the control registers of the JAZ-PX module.
Power ModeSets the power mode of the JAZ-PX module to either battery power or external
power. You must manually set the power mode to external power to access
intensities greater than 0 (400V) and flash rates higher than 200 Hz (5 msec).
Using the JAZ-PX module on Jaz battery power at flash rates greater than 200 Hz
can result in unexpected behavior.

Setting JAZ-PX for Triggered Mode
Some applications may require you to synchronize the various elements in the system to a system-wide
trigger signal. This mode would be comparable to the legacy “single strobe” mode in that the PX lamp
flashes can be synchronized to the spectrometer integration periods. However, the procedure below will
result in multiple synchronized flashes per integration period rather than just a single flash per integration
period.

Operating JAZ-PX from SpectraSuite
Although the JAZ-PX module’s internal timing cannot be set directly from SpectraSuite, this software can
still easily control the PX flash by selecting the appropriate triggering options. To control the JAZ-PX via
SpectraSuite, the JAZ-PX module should operate in Triggered mode (not Free Running mode) and use
the Jaz internal trigger to control its flash timing. Ideally, the Jaz internal trigger should also be used to
synchronize the lamp flashes to the integration periods of any spectrometers in the system. Additionally,
the output of the JAZ-PX can be quickly enabled or disabled via the Strobe/Lamp Enable check box
above the graph.
Getting Started using JAZ-PX with SpectraSuite
► Procedure
1.In SpectraSuite, right click on the Jaz icon and select Spectrometer Features.
2.In the Spectrometer Features dialog box, select the Internal Trigger tab.
Set the Trigger Source to Internal and select an internal trigger period of 10 ms. This setting

Acquisition | Channel 0 | Int Time.
5.
Click the Strobe/Lamp Enable checkbox at the top of the screen.
Synchronizing a Spectrometer Module to a JAZ-PX Module (recommended)
► Procedure
1.Highlight the Acquisition |Channel x | Int Time line in the Data Sources pane for the channel
that you wish to synchronize.
2. Select the External Hardware menu item. Although this option is named External Hardware, it
really just selects the Jaz stack trigger as the trigger source for the JAZ-PX module. Since we
have set the stack trigger to be driven by the DPU’s internal trigger (Step 4 above), this internal
trigger will synchronize the PX and the start of the integration period. (Note that the length of the
integration period is still set by the Integration Period field.)
Caution
Set the stack trigger source to Internal (Step 3 above) before setting the
spectrometer’s trigger source to External Hardware or the spectrometer will freeze.
To return the spectrometer module to Free Running mode, you must assert a trigger
pulse through the Jaz external trigger, or you must restart the Jaz.

Operating the JAZ-INDY Module
JAZ- INDY Module Overview
The Jaz Indy is a multifunction module that allows the Jaz system to communicate with data standards
common to industrial applications – in particular, RS-232 and RS-485 – and provides both analog and
digital inputs/outputs. When combined with the Jaz triggering capabilities and multichannel capacity, the
Indy module makes Jaz an attractive optical-sensing option for multipoint sampling, reference monitoring
and other applications in process and lab environments.
The Jaz Indy Module is installed in the vertical Jaz stack and operates as part of the fully integrated
spectrometer system. The module has 4 analog I/Os software-configurable to -5 to +5 volts and 8 digital
I/Os. Data for analog inputs and outputs can be processed in values such as volts or counts. The module
complies with RoHS, CE and FCC Part 15, Class A requirements.
JAZ-INDY Module Features
Experiments connect directly to Indy module for analog and digital I/O
Enables Jaz to communicate with other devices via RS-232/RS-485 standards
Provides measurement and control for portable, laboratory and “light-industrial” setups

recalibrate the module so that it matches your equipment.
You can calibrate the following on the JAZ-INDY module:
Four voltage outputs

5: Operating the JAZ-INDY Module
Four single-ended voltage inputs and the two differential inputs
4-20mA transmitter
4-20mA receiver
Calibrating the Voltage Outputs
The JAZ-INDY module provides four analog voltage outputs on its 26-pin connector (outputs 14 are
mapped to pins 5, 14, 23, and 4 respectively, where pins 2, 12, or 15 can be used as analog ground).
►
Procedure
1.Connect an external, calibrated voltmeter (providing at least 5 total digits resolution) to each
output pin to calibrate it. No load should be connected to the output pin; it should be connected
to a voltmeter and nothing else.
2.Set the output voltage (in counts) until the voltmeter reads as close as possible to -4.5V. Record
this value to be used later.
3.Set the output voltage (in counts) until the voltmeter reads as close as possible to 0.0V. Record
this value to be used later.
4.Set the output voltage (in counts) until the voltmeter reads as close as possible to 4.5V. Record
this value to be used later.
5.Using the Jaz menu or SpectraSuite software (see Calibrating the 4-20mA Transmitter
The JAZ-INDY module provides a 4-20mA current controller that must be calibrated. There are only two
setpoints for this controller: 4mA and 20mA. The controller can be calibrated by passing the current
directly through a digital multimeter (ensure first that the meter is rated to withstand at least 30mA to
prevent damage). JAZ-INDY provides an excitation source that can be used to power the current
transmitter (pin 19). If you use this internal source, set it to 20V (this can be done in SpectraSuite) and
ground the output of the current loop (after passing through the multimeter) back to the JAZ-INDY
module (using any of the ground pins).
Calibrating the 4-20mA Receiver
Once the 4-20mA transmitter has been calibrated, it can be used to calibrate the receiver.
►
Procedure
1.Move the ground connection from the current loop used in calibrating the 4-20mA transmitter so
that it is instead connected to pin 11 (4-20 Sense).
2.Vary the current output of the 4-20mA transmitter until 4mA is reached.
3.In the Jaz menu, select Calibrate | 4-20 mA Rx | Minimum. Set the mA value, if needed, to 4.0
and then select Sample 4.0mA.

measured in Step 2.
b.Select Zero and enter the counts measured in Step 3.
c.Select Maximum, then change the voltage to 4.5 and set the counts to the value you measured
in Step 4.
7.Repeat this procedure for each of the output channels.
Calibrating the Voltage Inputs
Once the voltage outputs are calibrated, they can be used to calibrate the voltage inputs. These can be
found on pins 3, 13, 22, and 21. Note that the output voltage may sag slightly when connected to the
voltage inputs, so it is necessary to keep the voltmeter connected to the joined input and output pins to
compensate.
►
Procedure
1.Set the output voltage (in counts) until the voltmeter reads as close as possible to -4.5V.

6.
Repeat this procedure for each of the input channels.
Note
There are two special channels (Vin 1 – Vin 2 and Vin 3 – Vin 4) that are differential (the
hardware finds the difference between the corresponding input pins). To calibrate these,
You must use two voltage inputs at once and set them to opposite values (e.g., set one to
+4.5V, the other to -4.5V, to calibrate the differential input at +9V). The process is the
same as described above, except that the differential inputs should be calibrated at -9V,
0.0V, and 9V.
For the 0.0V measurement, set both of the voltage outputs being driven in to zero. For the
non-zero measurements, both voltage input/output pairs should be confirmed on the
external voltmeter prior to finishing the calibration.

Appendix A
Calibrating the Wavelength of
Jaz
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
Jaz spectrometer.
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 polynomial:
= I + C1 p + C2 p2 + C3 p
p
Where:
= 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

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

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. 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.
A Jaz spectrometer module
An optical fiber (for spectrometers without a built-in slit, a 50-

and AnalysisTookPak-VBA.
Calibrating the Wavelength of the Spectrometer
► Procedure
Perform the steps below to calibrate the wavelength of the spectrometer:
1.Place SpectraSuite 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.
5.Use the spreadsheet or calculator to calculate the wavelength calibration coefficients. In the
spreadsheet program, find the functions to perform linear regressions.
If using Quattro Pro, look under Tools | Advanced Math
If using Excel, look under Analysis ToolPak
6.Select the true wavelength as the dependent variable (Y). Select the pixel number, pixel number
squared, and the p
ixel number cubed as the independent variables (X). After executing the
regression, you will obtain an output similar to the one shown below. Numbers of importance are
noted.

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.
