Product Details

The PX-2 Pulsed Xenon Lamp is a high flash rate, short-arc xenon lamp with output from 220-750 nm.

The PX-2 operates at speeds up to 220 Hz and offers excellent pulse-to-pulse stability. It can be triggered by an external TTL pulse and offers software control of the flash rate.

Spectrometer sampling can be altered so that a variable number of flashes are observed during each integration period. For example, in Single Mode operation, a single flash occurs during each integration period so you can easily synchronize both the xenon lamp and detector. In Multiple Mode, a steady, consistent light exposure is provided for each integration period, ensuring reliable absorbance and reflection measurements.

Product Overview

  • Adjustable flash rate -- optimizes measurements of light sensitive samples
  • Simple operation -- software control of flash rate and synchronization
  • Reliable performance -- excellent pulse-to-pulse stability for long measurements
