DH-2000-BAL Ocean Optics Deuterium-Tungsten source 210-2500nm


Balanced Deuterium Tungsten Source, 210-2500nm, 1000 hrs (KB).


The DH-2000-BAL Deuterium Tungsten is a UV-NIR light source used for absorbance, reflection or fluorescence measurements.

  • Innovative filtering eliminates D-alpha line in deuterium source
  • Balanced output from 215 to 2500 nm eliminates problems associated with saturation
  • Powerful and stable deuterium (25 W) and halogen lamps (20 W) in a single light source
  • An integrated shutter helps protect light-sensitive samples
  • Easy-to-replace, pre-aligned bulbs increase productivity

Included with the Product:

  • Power cord
  • UV safety goggles
