Te02 Visible Acousto-optic Tuneable Filters, Acceptance Angle 3.5-6.0°

Manufacturer's part number :


Manufacturer Isomet


Description :

The AOTF range of acousto-optic devices are solid state optical filters. The wavelength of the diffracted light is selected according to the frequency of the RF drive signal. Isomet-grown tellurium dioxide (Te02), which has been oriented for off-axis mode operation, is utilised as the interaction material. Fast access times and fine spectral bandwidths make these filters ideal for selecting discrete lines from a multi-line laser sources. The best diffraction efficiency is obtained with linearly polarised input light.
