This document is the user guide for MC2000B Optical Chopper. It describes the features and characteristics of the product, including chopper blades, front and rear panel description, setup, and basic operation.
The MC2000B is a precision optical chopper that creates pulses of light from continuous beams using a phased-locked loop (PLL) motor speed control design. It features an internal crystal-stabilized frequency synthesizer and supports synchronization with external reference signals, including other MC2000B units or DSP lock-in amplifiers.
