Description

It is used as an acousto-optic material and a conditional glass former. The glasses of tellurium oxide have high refractive indices. Owing to the transmission into mid-infrared part of the electromagnetic spectrum, tellurium oxide is of technological interest for optical waveguides. It is also employed in optical fibre amplification.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
