AvaLight-XE Pulsed Xenon Light Source

The AvaLight-XE is a pulsed xenon light source, perfect for ultraviolet applications like fluorescence. When connected to your AvaSpec spectrometer through the IC-DB26-2 cable (sold separately), the flashes are synchronized with the data collected by the spectrometer. The number of flashes per scan can be selected in AvaSoft.

With a special DUV bulb, the AvaLight-XE can be used for deep-ultraviolet applications (below 200 nm). A special direct-attach cuvette holder is available for your fluorescence applications. For transmission measurements, the Avalight-XE can be used in conjunction with the CUV-ATT-DA which has an iris attenuator to limit the light output and to avoid saturation.
