AOTF1331
AO Tuneable Filter
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.
