Product Description

SR540 Optical Chopper inner and outer holes dual frequency design chopper plate
SR540 Optical Chopper can meet all your optical modulation requirements, whether for single beam experiments or double beam studies. It features a 4-digit digital frequency display, front panel frequency control, analog voltage frequency control and selectable operating mode with two reference outputs. The two choppers have a 5/6 aperture and a 25/30 aperture, and can achieve optical modulation from 4Hz to 3.7KHz. The reference frequency is consistent with the actual chopper frequency. The closed-loop control system makes the chopper output more stable.
