SE3001 Optical Chopper

SE3001 Optical Chopper is high-precision optical equipment with its chopper frequencies from 1 Hz to 10 kHz. With the advantage of PID technology and high-quality motor, the frequency accuracy of SE3001 is up to 0.5%. SE3001 consists of a console, a chopper head and a control line. The main function of the console is to control the speed of the motor to achieve the target speed. The chopper head is mainly composed of a base and a motor with a blade.
