Our pulsed Xenon light source is used in applications where a long lifetime and high output power is needed, such as in fluorescence measurements. This is an affordable UV source, but the spectral output is not as smooth and continuous as the AvaLight Halogen and Deuterium light sources.
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 light source can be used in conjunction with the CUV-ATT-DA, which has an iris attenuator to limit the light output and avoid saturation.
