Optimum Illumination for CROWNTECH’s

SM Series Spectrometers

This lamp is a near Black Body source of light in the visible to near IR spectral

region. It has been designed to produce the maximum illumination from a Black

Body source into a fiber bundle. This light source is primarily for use with the

CROWNTECH Series spectrometers.

The lamp assembly comes in a 3 watt or a 5 watt tungsten/halogen lamp confi-

guration, an aluminum housing, and a wall transformer as a power supply. The power

input is regulated inside the lamp housing to assure a ± 0.4% stability over the current

range. Current regulation ensures color temperature stability.

The tungsten/halogen lamp used inside the lamp has a nominal color

temperature of 2800ºK and an average life of 10,000 hours at this color

temperature.
