WATER-COOLED TYPE
DEUTERIUM LAMPS
L1314, L1835
High Intensity, 150 W Type,
Vacuum UV (from 115 nm) Light Source - L1835
The L1314 and L1835 are water-cooled 150 W deuterium lamps that
deliver a radiant intensity 3 to 4 times higher than standard 30 W deu-
terium lamps. The lamp bulb is enclosed in a cylindrical metal jacket
specially designed for water cooling. The L1314 has a synthetic silica
window for an efficient emission of UV radiation, and the L1835 em-
ploys a MgF2 (magnesium fluoride) window which even allows emit-
ting vacuum UV radiation. Select the lamp that matches wavelengths
required by your application. Vacuum flanges are also available as op-
tions in the L1835 for easy mounting to a vacuum chamber.

NOTE: ATypes L1314 and L1835 cannot be
operated without cooling water passing
through them. Care should be taken that
the lamp is positioned properly so that
the two nozzles are aligned vertically,
with the water flowing into the jacket at
the bottom nozzle and leaving the jacket
at the top nozzle. If this arrangement is
not observed, there is a danger of
damaging the lamp due to overheating.
