3.0-57µm PEM Optical Heads, Aperture 23mm, 57KHz

Manufacturer's part number :

II/CF57

Manufacturer Hinds

Hinds

Description :

II/CF57 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/CF57 photoelastic modulator is particularly useful in the far infrared spectrum from 3.0 to 57µm with an aperture of 23mm and a frequency at 57KHz. Hinds application scientists are available to consult on the optimal material and model for your particular experimental setup.
