An optomechanical modulator (aka an optical chopper) is widely used in different optical experiments. It modulates different light sources with given frequency for their subsequent analysis. The joint use of the optical chopper with the lock-in amplifier greatly facilitates low-amplitude signal detection against high-level background noise. The exchangeable blades selection offers wide modulation frequency range.
The OCV-6300F model features a built-in visual frequency indicator that allows precise selection of the chopping frequency without any external devices. The unit also has a sync output.
The standard supply package includes modulator driver, power supply and 1 blade of customer's choice. Additional blades are ordered separately.
