FEATURES
APPLICATIONS
This light source L7893 incorporates a highly
stable Deuterium lamp and a Tungsten lamp
into a single compact housing with an optical
fiber light guide. The combination of these two
lamps covers a wide spectral range from 200
nm to 1100 nm, yet offers highly stable light
output and long service life. This light source
L7893 series is ideal for a compact analytical
equipment such as miniature grating units,
portable spectrophotometers and reflection
meters.

1. These light sources radiate strong UV rays
which are harmful to the eyes and skin. Do
not look directly into the lamp or allow the
light rays to directly strike the skin. Always
wear protective glasses or other protective
gear when operation.
2. High voltage is used to operate the lamp.
Use extreme caution to prevent electric
shocks.
The guarantee period will be one year ship-
ment or specified life time comes first. The
area of guarantee is limited to replacement of
the faulty instrument. Faults resulting from nat-
ural disasters and incorrect usage will also be
excluded from guarantee.
