For accurate wavelength measurements, the prism
mount must remain fixed, such that the back face
of the prism is perpendicular to the incoming light
source (Figure 3).
d) From the bottom side of the degree plate,
place a lock washer and wingnut on the
threaded post. Rotate the wingnut to help
secure the mount against the spectrophotometer
table.
4. Attach the Infrared Filter Bracket to the Infrared
Light Sensor (if using the Infrared Light Sensor)

To observe infrared wavelengths, use the Infrared
Sensor instead of the High Sensitivity Light
Sensor.
a) To replace the high sensitivity light sensor, rotate
the threaded post clockwise to loosen the
attachment and remove the light sensor.
b) Place the base of the filter bracket over the front
hole of the light sensor mount, such that the hole
in the bracket base aligns over the front hole on
the mount and the front hole of the light sensor
arm.
c) Place the Infrared Light Sensor over the base of
the bracket. While holding the sensor in place
with one hand, use the other hand to insert the
threaded post from beneath the sensor. Rotate
the post until the sensor holds firmly in place
against the bracket and mount. The glass filter
should fit snugly against the sensor, with the
bracket under the case (Figure 4).
