TeO2
 
Tellurium Dioxide (TeO2 or Paratellurite) is an excellent piezo-optical material. It is extensively used because of it's high acousto-optical figure of merit in making acousto-optical modulators, imaging devices, splitters,deflectors, tunable polarisation filters, radio frequency spectral analysers and other acousto-optoelectronic equipment for laser radiation control.¡¡¡¡ Single acousto-optical crystal Tellurium Dioxide (TeO2) is applicable in areas of research, development, education & production: photonics, optic, laser technology, dosimetry, telecommunications, electronic. Hangzhou Lambda Tech.can provide the TeO2crystals in boules, rods, slabs or wafers.
