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.
