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 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.

PX-2 Installation and Operation Instructions Note If you are connecting the Breakout Box to the USB4000 Spectrometer, you must first attach the USB-ADP-BB adapter to the spectrometer. Configuring the PX-2 After setting up the PX-2, you must configure it to operate with the spectrometer and software. ► Procedure 1. Connect an optical fiber to the SMA 905 Connector on the front panel of the PX-2. 2. Turn the PX-2 on via the power switch on the rear of the unit. 3.

PX-2 Installation and Operation Instructions Multiple Mode In Multiple mode, the flash timing (pulse rate) is determined by the spectrometer:  S2000 Spectrometer – Flash timing is determined by the JP3 jumper block setting. See your S2000 Spectrometer manual for more information.  All other OOI spectrometers – The Continuous strobe rate is either fixed or software controlled. See the SpectraSuite Spectrometer Operating Software Installation and Operation Manual for more information.
