Basic Optics Linear Translator 012-06551A
Suggestions for Using the Linear Translator
Light Intensity of Diffraction Patterns
EQUIPMENT NEEDED
– Optics Bench (part of OS-8515) – Linear Translator (OS-8535)
– Aperture Bracket (OS-8534) – Slit Accessory (OS-8523)
– Diode Laser (OS-8525) – Rotary Motion Sensor (CI-6538)
– Light Sensor (CI-6504A)
Use the Diode Laser and Slit Accessory to produce a diffraction pattern. Mount the Linear Translator on the
Optics Bench so the rack is perpendicular to the Optics Bench. Use the Light Sensor to measure the intensity of
light in the diffraction pattern. Use the Rotary Motion Sensor mounted on the Linear Translator to measure the
position of the Light Sensor as it moves through the diffraction pattern.
(The description for this experiment starts on the next page.)
Light Intensity versus Distance
EQUIPMENT NEEDED
– Optics Bench (part of OS-8515) – Linear Translator (OS-8535)
– Aperture Bracket (OS-8534) – Light Source (part of OS-8515)
– Rotary Motion Sensor (CI-6538) – Light Sensor (CI-6504A)
Use the Light Source to produce a “point source” of light. Mount the Linear Translator on the Optics Bench so the
rack is parallel to the Optics Bench. Use the Light Sensor to measure the intensity of the light. Use the Rotary
Motion Sensor mounted on the Linear Translator to measure the position of the Light Sensor as it moves relative
to the Light Source.
