The PEM200 photoelastic modulator is an instrument used for modulating or varying (at a fi xed frequency) the polarization of a beam of light.
The basic PEM system includes the PEM-200 controller and the optical head (Figure 1).
By varying the material, size, and shape of optical element, and coupling closely-matched drive and control circuits to the PEM optics, Hinds Instruments has developed a range of photoelastic modulators for a variety of applications in a wide spectral region (UV to far-IR).
