PX-2
Pulsed Xenon Light Source
Installation and Operation Instructions
Description
The PX-2 Pulsed Xenon Light Source is a high flash rate, short-arc xenon lamp for applications
involving absorbance, reflection, fluorescence and phosphorescence measurements, and especially for
measuring optically or thermally labile samples.
The PX-2 has an SMA 905 Connector that couples to Ocean Optics miniature fiber optic
spectrometers and accessories, including optical fibers, cuvette holders, probes and other sampling
optics.
The PX-2 operates at speeds up to 220 Hz, offers excellent pulse-to-pulse stability, and has two trigger
modes for software control of the flash rate. Any external TTL positive pulse can be used to trigger the
PX-2. When it is coupled to a spectrometer, you can easily synchronize operation of both the light and
detector.
Because it produces a pulsed signal, the PX-2 is less likely to contribute to solarization in optical fiber
assemblies, which can occur when fibers are illuminated with signals less than 260 nm.

PX-2 Installation and Operation Instructions
Parts Included
The PX-2 ships with the following items:
PX-2 Pulsed Xenon Light Source
12 VDC power adapter
15-pin interface cable
Additional Accessories
The following are additional accessories available from Ocean Optics that you may need, depending
on your system set-up:
USB2000/PX-2 adapter (USB-ADP-PX2)
Replacement bulb (PX-2-B)
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.
Dangerous voltages are present in the PX-2. Do not operate the PX-2 without the
housing intact.
The SMA 905 Connector can get hot during operation. Allow the lamp to cool
after operation before handling.
Do not drop the instrument, as this may cause permanent damage to the unit.
Handle with care.
Connecting the PX-2
The set-up procedure differs, depending on the spectrometer to which you are connecting the PX-2.
Connecting to an S2000 Spectrometer
► Procedure
1. Remove the PX-2 from the product packaging.
2. Plug the 12 VDC power supply into a wall outlet, then connect the barrel connector on the
power supply to the rear of the PX-2.
3. Connect the 15-pin cable to the rear of the PX-2, and then connect the other end to the 15-pin
connector on the S2000 Spectrometer.
You have now connected the PX-2 for operation with the S2000 Spectrometer.

PX-2 Installation and Operation Instructions
Connecting to a USB2000/USB2000+/USB4000/HR2000
Spectrometer
The USB2000 and HR2000 Spectrometers have a 10-pin connector. The
USB2000+/USB4000/HR2000 have a 20-pin connector. For these spectrometers, you need to use the
USB-ADP-PX2 serial adapter.
► Procedure
Follow the steps below to connect the PX-2 to a USB2000/HR2000 Spectrometer:
1. Remove the PX-2 from the product packaging.
2. Connect the USB-ADP-PX2 Adapter to the spectrometer’s accessory connector. For
USB2000+/USB4000/HR2000 Spectrometers with the 20-pin connector, skip the first column
of pins (A1 and A2) when plugging in the adapter.
3. Tighten the jackscrew to hold the adapter in place.
4. Connect the DB15 cable that came with your PX-2 to the USB-ADP-PX2, then to your PX-2
light source.
You have now connected the PX-2 for operation.
Connecting to Ocean Optics Spectrometers with a 30-pin
Connector
Our other spectrometers such as the NIRQuest, Maya, QE65000 and HR4000 use a 30-pin accessory
connector.
► Procedure
Follow the steps below to connect the PX-2 to spectrometer with a 30-pin accessory connector:
1. Remove the PX-2 from the product packaging.
2. Connect the HR4000-CBL-BB ribbon cable to the spectrometer’s 30-pin accessory connector.
3. Connect DB15 cable assembly to the spectrometer’s ribbon cable and the other end to the PX2’s 15-pin connector.
You have now connected the PX-2 for operation.
Connecting the PX-2 Using the Breakout Box
The Breakout Box offers another option for connecting the PX-2 to our spectrometers with the 30-pin
connector. The Breakout Box is a passive module that separates the signals from the 30-pin port of the
spectrometer into an array of standard connectors and headers. You’ll want to use the Breakout Box if
you need multiple interfaces to your spectrometer. See the Breakout Box Installation and Operation
Instructions for information on using the Breakout Box.
