750 nm - 3.0µm PEM Optical Head, Aperture 13mm

Manufacturer's part number :


Manufacturer Hinds


Description :

PEM II/FS84 Series II photoelastic modulator uses a symmetric or octagonal shape for the modulator optical element. A two-dimensional standing wave in the optical element doubles the retardation available for a given drive voltage. PEM II/FS84 photoelastic modulator covers a spectral range from 750nm to 3.0µm. Hinds application scientists are available to consult on the optimal material and model for your particular experimental setup.
