Te02 IR Acousto-optic Tuneable Filters, Acceptance Angle 5.0°

Manufacturer's part number :

AOTF1331

Manufacturer Isomet

Isomet

Description :

The AOTF1331 Acousto-Optic Tuneable Filter has been optimised for operation in the wavelength range of 2500 nm to 4000nm. The wavelength of the diffracted light is selected by application of a corresponding RF drive frequency. A thermal electric cooler (TEC) is fitted for applications requiring high temperature stability. Isomet grown Tellurium Dioxide (TeO2), is utilized as the interaction material.
