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.

Avesta is participating in Ultrafast Phenomena 2018 conference and tabletop exhibition in Hamburg, Germany (15-20 July). We would be glad to discuss any of the ongoing and future projects with the ultrafast community at our tabletop. Hope to see you soon!
Avesta’s facilities will be closed for the New Year break from 30 Dec 2017 till 08 Jan 2018. We will resume all operations on 09 Jan 2018. However, we hope to provide periodic e-mail correspondence during the holidays. We wish you a fruitful and prosperous Year 2018!
