With a compact structure, this Deuterium Tungsten-Bromine Lamp produces a powerful, stable output from 180 to 2500 nm. The continuous output combines the spectra of Deuterium and Tungsten-Bromine lamps in a single optical path, and the two bulbs can be lit separately, depending on application. Warning: Exposure to the light spot of Deuterium should be avoided to protect eyes from UV radiation.
