Compact, Deuterium Halogen Light Source

USB UV/VIS spectrometer
UV/VIS light source

The AvaLight -DHc is both a deuterium light source and a halogen light source, providing you with adequate light between 200 and 2500nm for nearly all absorbance chemistry applications and more.


Deuterium emits light between 200 and 550nm, then the halogen takes over and provides illumination up to 2500nm. Coupling to the rest of your spectroscopy system is easy with the standard SMA connector.

This light source is recommended in setups with large fibre cables or direct attach accessories such as cuvette holder in the form of the CUV-DA, due to its relatively low output energy. The integrated TTL-shutter makes saving a dark measurement very simple in combination with AvaSoft if the spectrometer is interfaced with your PC via an IC-DB26-2 cable.

As an option, the AvaLight-DHc is available in a rack mountable version, to be used in the 19” rack or the 9.5” desktop system.

Highlights of the AvaLight-DHc are...

  • Combined Deuterium-Halogen

  • Low cost

  • Integrated TTL-shutter
