CH

The tuning fork chopper is a fixed frequency electromechanically driven light chopper. Blades attached to moving tines of a fork modulate a light beam. Chopping frequency ranges from 10 Hz to 6 KHz, apertures up to 15mm are practical in the lower frequencies (under 100 Hz), 0.5mm at 3 KHz and 0.2mm at 6 KHz.

CH series choppers have dark or bright blades (vanes) as standard; mirrors, lenses or gratings optional.
