Product Description

Detailed Description:

TeO₂ is a kind of acousto-optic material with high quality factor. It has good properties of birefringence and optical rotation with low velocity of propagation along (110) axis.Under the same clear aperture, the acousto-optic device produced by TeO₂ crystals has the advantages of the orders of magnitude improvement in resolution, fast response speed, small driving power, high diffraction efficiency, as well as stable and reliable performance.

TeO₂ crystals are ideal single crystal material used to produce different kinds of acousto-optic device, such as acousto-optic deflector, modulator, resonator and tunable filter.
