Product Description
Tellurium Dioxide Crystal (TeO2) is one of the best Acousto-Optic crystals even grown, and extensively used in AO modulators, deflectors, AO tunable filters (AOTFs), laser Q-switches, RF spectrum analyzers. We provides various laser-grade Tellurium Dioxide devices.
Application:
TeO2 crystals can be used to produce kinds of acousto-optic device, such as acousto-optic deflector, acousto-optic Q-switched and SAWD. Thus, these crystals are widely used in lidar, the scanning of TV and large screen's displayer, the optical memory of photon computer and laser communication.
We can provide 2inch, 3inch 4inch TeO2 ingots and all specs of wafers,bars, and blocks. Any of your questions and comments are warmly welcome.
