Optical Chopper

Overview

Sr540 optical chopper is a device that directly converts a beam of weak light (including constant and slow changing light) into AC signal through mechanical chopping. Chopper has stable frequency and high precision. It is a necessary component for modern modulation optical measurement. It is mainly used for fiber amplifier characteristic measurement, fiber grating sensing, optoelectronic material characteristic analysis and other research, from simple experiment to double beam and internal modulation measurement. Sr540 has voltage control input, four digit digital frequency display, ten segment frequency control, and reference output of two optional working modes. 4hz-3.7khz chopper frequency, single beam and double beam modulation, low phase jitter, sum frequency and difference frequency reference signal transmission.
