LIGHT H2D2 LIGHT SOURCE UNIT
SOURCE L11798/-01, L11799/-01
OVERVIEW
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 our 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. This feature makes it much more convenient
and easy to use than ordinary water-cooled lamps.
The H2D2 can be used in various applications and en-
hances equipment sensitivity and throughput.
