Description

Pure and Efficient polarization modulation

 

Hinds Instruments is the world's leading developer of technologies based on the principles of polarization modulation. Photoelastic modulators (PEMs) are key components in a diverse range of photonics applications. As such, Hinds has become a key contributor to a wide range of critical polarization-based measurements.

 

PEMs are made of isotropic optical materials and operate at a resonant frequency. Unique properties of the PEM include:
 

- Polarization purity
- Large aperture
- High power handling capability - up to 5 GW/cm2 for some devices
- Large acceptance angle
- Wide range of products for different spectral regions, from vacuum UV to Terahertz
- Retardation stability
- Durability – some PEMs are still in use from 1977
