Dual PEM Photoelastic Modulator, Aperture 27mm

Manufacturer's part number :

PEM 100 II/FS42-47

Manufacturer Hinds


Description :

The Dual PEM 100 II/FS42-47 systems also employ high quality fused silica as the optical material and have a transmission range of 170nm to 2.6µm. Both models are completely functional in the visible and near IR light spectral regions. However, the II/FS42-47 system has the benefit of a larger aperture. This is especially useful if the light source has a large beam diameter or more than one light source is to be accommodated. This dual PEM is typically used in a Stokes polarimeter system to measure the orientation of the linear component of light emitted from a beam of deuterium atoms injected into tokamak plasma. The II/42-47 is also used in Stokes polarimetry measurements and provides a more compact optical head configuration
