Free Space Acousto-Optic Tunable Filters
The Brimrose Acousto-Optic Tunable Filter (AOTF) is a solid state acousto-optic device with no moving parts. It functions as a tunable transmissive filter. It is able to precisely and rapidly adjust the wavelength, and intensity of the diffracted/filtered light by varying the RF power.
Brimrose offers both standard and custom AOTFs. AOTFs are used widely in numerous optical systems and applications, especially in industrial or process control near-infrared (NIR) spectroscopy applications.

* Available in low or standard resolution.
Brimrose's AOTF technology uses a Tellurium Dioxide (TeO2) crystal. The AOTF operates in the NIR region in a so-called non-collinear configuration. The acoustic and optical waves propagate at quite different angles through the crystal.
Material: TE – Tellerium Dioxide (350-5000 nm) QZ – Quartz (SiO2)
Options:
S – Standard Resolution
H – High Resolution
EH – Extra high Resolution
UH – Ultra high Resolution
