Product Description

Quartz/Optical Glass: Quartz glass sheets are usually colorless and transparent, with a visible light transmittance of more than 85%. Key features include exceptional heat resistance, acid and alkali resistance, high light transmittance, electrical insulation, and chemical stability.

In terms of optical properties, it transmits far ultraviolet light (the best among UV transparent materials), visible light, and the near-infrared spectrum. Due to its resistance to high temperatures and very small thermal expansion coefficient, it maintains high stability in harsh environments, making it an essential material for precision optical instruments.
