Optical glass dome is widely used in high temperature resistant.
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).
