PX-2

Pulsed Xenon Light Source

Please contact us online for more information about ordering this product.

View Product Variations

The PX-2 Pulsed Xenon Lamp is a high flash rate, short-arc xenon lamp for the ultraviolet (UV). With an output from 220-750 nm, it is ideal for absorbance and reflection measurements. Because of the shorter duty cycle the PX-2 is also useful for fluorescence and phosphorescence measurements.

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

The spectrometer sampling can be altered so that a variable number of flashes are observed during each integration period. In the Single Mode of PX-2 operation, a single flash occurs during each integration period so you can easily synchronize operation of 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.

The PX-2 has an SMA 905 output connector and seamlessly integrates with Ocean Optics miniature fiber optic spectrometers and accessories, including optical fibers, cuvette holders, probes and other sampling optics.

  • Adjustable flash rate optimizes measurements of light sensitive samples
  • Experiment setup is easy with software control of flash rate and synchronization
  • Excellent pulse-to-pulse stability for long measurements

Included with the Product:

  • 12 VDC power supply.
  • 15-pin interface cable, which connects the lamp to the spectrometer.
