OCV-6300. Compact Optical Chopper
• 14-6300 Hz modulation frequency
• Sync output
• High frequency stability
• Small footprint
• The OCV-6300F model with a frequency indicator
Product overview
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-6300 is the simplest model without visual indication of modulation frequency, but it has a sync output.
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.
