Full-Range Compact Light Source – AvaLight-DHc

The AvaLight-DHc has both a halogen light source and a deuterium light source, providing users with sufficient light between 200 and 2500 nm for virtually all absorbance chemistry applications. Deuterium releases light between 200 and 550 nm, where the halogen takes over up to 2500 nm. Coupling to the rest of one’s spectroscopy system is easy with the SMA connector.

This light source is recommended in settings with large fiber cables or direct-attachment to a cuvette holder such as the CUV-DA, because of its comparatively low output energy. The integrated TTL-shutter makes saving a dark measurement extremely simple in combination with AvaSoft (additional IC-DB26-2 necessary).

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

  • Combined Deuterium-Halogen
  • Integrated TTL-shutter
  • A direct-attach cuvette holder CUV-DA is available for absorbance or fluorescence measurements
  • Low cost
