TeO2
TeO2 is an acousto-optical material with high-quality factors, such as good birefringence and optical performance, slow sound propagation in the [110] direction, and the optical devices can improve by orders of magnitude, fast response speed, low driving power, high diffraction efficiency, and stable and reliable performance.
It is the ideal single crystal material for making various acoustic and optical devices, such as acoustic and optical detect, modulators, resonators, and adjustable filters.CasCrysTech (CCT) provides high quality Tellurium Dioxide (TeO2) crystals upon request from customers.
