ROC is designed to out-perform the traditional optical chopper in many ways
The Reflective Optical Chopper offers greater frequency range with faster chopping speed without alteration of the beam size. The Modulator component works as a reflective diffraction grating, chopping the beam by varying between an unpowered flat mirror-state and a powered diffractive state. With a module that easily fits into a standard 1” optical mount, the ROC is operable within minutes of unpacking. The ROC can be operated either in standard mode with the on-board signal generator, or in custom mode using a user-generated 5-volt TTL signal.
