The Optical Choppers offered by Hinds Instruments are resonant devices designed to work at one frequency. We offer two ways to chop light: a High Speed Optical Chopper (HSOC) and a Photoelastic Modulator (or PEM).

High Speed Optical Chopper

The HSOC is calibrated for one wavelength, in the range of 400 nm – 750 nm. However, it can be used within a +/- 10% range from the center wavelength without a change in calibration. The frequencies to choose from are 40, 50, and 60 kHz. The HSOC comes in a small, single enclosure package. All optics and drive electronics are included.

Photoelastic Modulator

The PEM is the most versatile choice. The wavelength range can be from 130nm – 18µm depending on the model of optical head chosen and the PEM can be used for non-chopping applications in separate set ups. Its operation as a chopper over large wavelength ranges requires additional optics (one linear and one circular polarizer) to convert the PEM into a chopper system. These can be obtained from Hinds Instruments or purchased separately by the user. The basic PEM comes in three modules: the optical head, the drive electronics, and the control electronics. Frequencies range from 20-84 kHz.

Custom configurations and accessories are available for this product family. Please contact a representative for more details.
