Description
The Spectrophotometer allows you to view and mea-
sure the spectral pattern (spectrum) produced by a
light source. The Collimating Slits and Collimating
Lens produce a narrow beam of parallel light rays.
The Grating disperses the beam of light into a spec-
trum with different colors at different angles but with
all of the light of a given color in a parallel beam. The
Focusing Lens focuses these parallel beams of color
into spectral lines (see Fig. 2). The narrow slit on the
Aperture Disk (part of the Aperture Bracket) allows
light of a single color to enter the High Sensitivity Light Sensor. The High Sensitivity Light Sensor (included
with the Spectrophotometer System) measures the intensity of the light while the Rotary Motion Sensor
(included with the Spectrophotometer System) measures the angle to which the light is diffracted by the Grating.
