General Information
2.1
System Overview
The Model 3502 Optical Chopper is used to introduce a periodic interruption of
a light path in an optical experiment resulting in an amplitude modulation,
which is useful for many small optical signal detection schemes. The modulation
frequency can be controlled from 4 Hz to 10.65 kHz. Full control is available
through the Model 3502 Optical Chopper Controller
’s front panel. In addition,
the Chopper Controller can be programmed over a USB communication
interface to set and measure the modulation frequency, adjust the interruption
phase, and perform all other operations available through the front panel.
