750 nm - 3.0 µm PEM Optical Head, Aperture 27mm

Manufacturer's part number :


Manufacturer Hinds


Description :

II/IS42 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. II/IS42 photoelastic modulator is particularly useful in the infrared spectrum from 750nm to 3.0µm. Hinds application scientists are available to consult on the optimal material and model for your particular experimental setup.
