High Intensity, 150W Type,
Vacuum UV (from 115nm) Light Source-L1835
The L1314 and L1835 are water-cooled 150W deuterium lamps that
deliver a radiant intensity 3 to 4 times higher than standard 30W
deuterium 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 employs
a MgF2 (magnesium fluoride) window which even allows emitting
vacuum UV radiation. Select the lamp that matches wavelengths
required by your application. Vacuum flanges are also available as
options in the L1835 for easy mounting to a vacuum chamber.
Types 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.

Since the L1835 vacuum UV deuterium lamp is often used while instal-
led onto a vacuum chamber, Hamamatsu provides the E3444 series
vacuum flanges specially designed for this purpose. Among these, the
E3444-02 has a flange conforming to ICF114 specifications, allowing
easy installation onto most vacuum chamber ports. The E3444 series
also includes a general-purpose "N" flange and JIS (Japanese Industri-
al Standards) specification flange. Select the desired type depending
on the vacuum equipment to be used.
The C3150 power supply is specifically designed for water-cooled
150W lamps. Various devices to provide stable light output are built
into this power supply. Protective functions such as a water flow rate
monitor and lamp lighting monitor also ensure safe and correct opera-
tion.
Since the L1835 is often used inside a
vacuum chamber, a special vacuum
flange is provided. It is designed to be
simply inserted over the lamp housing.
