The Optical Chopper System OCS100 provided by LBTEK includes a chopper head, its controller, and chopper blades. The chopper head uses a high-quality rare-earth magnet DC motor, combined with blades of different slot counts, the chopping frequency can cover 4 Hz to 10 KHz. The controller with a compact form factor uses a PLL phase-locked loop motor controller algorithm, providing stable chopping rate and phase jitter. The controller features a touchscreen and a pushable knob, all functions can be realized through the touchscreen and pushable knob, and remote host computer control can also be achieved via the USB interface. The host computer software supports secondary development in multiple languages including C/C++, Labview, C#, Python, and Matlab.

Please note: The chopper integrates a photoelectric switch, and the chopper should avoid contact with stray light sources, because the photoelectric switch may produce jitter when subjected to light pollution.

The OCB series chopper blades provided by LBTEK expand the chopping frequency range of the Optical Chopper. The OCB1F10HP high-precision dual-frequency blade is the standard chopper blade included with the OCS100. Additionally, single-frequency chopper blades such as the OCB1F10, the OCB1F10A with adjustable duty cycle, and the OCB2F57 harmonic chopper blade are also available. Customization of chopper blades with other slot types is also supported; please contact customer service for details.
