2. Reflected Visible Light and Emitted Infrared Light
In this experiment you will measure the profile of visible light reflected by the cavity
side of the cube and compare it to the profile of infrared light emitted by it.
Setup
1. Mount the Thermal Cavity on the Optics Bench.
Connect the thermistor sensor and power supply
(but don’t turn it on yet).
2. Mount the Linear Translator on the optics bench.
Assemble the Linear Translator, Aperture Bracket,
and Light Sensor (refer to the instructions accom-
panying the Linear Translator).
3. Arrange the apparatus so that the cavity side of the
cube is about 1.5 cm from the front of the Aperture
Bracket.
4. Turn the wheel on the Aperture Bracket to select
aperture #6.
5. Open the configuration file Reflected_and_Emitted_Light.ds.
