Description
The Hamamatsu part number L11798-01 Deuterium Lamp H2D2 Light Source Unit has a MgF2 window material with a guatanteed lifetime of 1000 hours. The H2D2 light source unit contains a high-brightness, high-end deuterium lamp (H2D2 lamp) that emits light at a brightness 6 times higher than other current deuteri- um lamps (L2D2 lamps). Despite its high brightness, the H2D2 is highly stable, has a long service life, and allows air-cooled operation by a specially designed housing.
Applications
