Description :

PEM photoelastic modulators change the polarization state of a light beam at frequencies between 20 and 100 kHz. The modulator optical element acts as a "dynamic waveplate" to produce an oscillating birefringence. This can convert linear polarized light into light which oscillates between circular, elliptical and linear states. For example, light which oscillates between left and right circular polarized light can be produced for use in circular dichroism measurements. The PEM 100 I/FS50-60 dual photoelastic modulator (PEM) system uses the series I of PEM. The Series I PEM has a rectangular shaped optic that, in essence, limits the useful aperture of the PEM. These small systems are practical when the light source has a small beam diameter. Therefore, if the application for the dual PEM involves a light source consisting of only one laser, this is a viable option.
