Product Description

High Purity Square Quartz Window Made In China


Fused quartz plates and discs are widely used throughout a variety of industrial applications.

Due to the unique properties of quartz it is ideally suited to applications that require a combination of chemical resistance, high temperature stability and high thermal shock resistance paired with low thermal expansion.

When used for window applications fused silica has a wide transmission spectrum from UV to IR.

Special properties of Quartz Glass:

Extreme wide spectral transmission range from deep UV to middle IR (wider than all other glasses).
Extreme high optical transmission and low optical absorption.
Low variation and disturbance of the refractive index in one solid piece and optical homogeneity from one melt to the next (reproducibility).
High resistance to high intensity laser radiation, which also applies to the UV spectral range (e.g. excimer laser).
High application temperature 1200 degrees C— almost four times higher than ordinary glass.
Low thermal expansion coefficient resulting in an extremely high temperature shock resistance allowing rapid heating & cooling.
