Fused Silica Discs

noe-glass-discs-1013979736-1

Newcastle Optics supply UV Fused Silica Windows and substrates, either custom made or from our standard stock. UV Fused Silica has high transparency in the UV ultraviolet 180nm to the (IR) infrared over 2.3 microns. The material is fluorescent free with high OH centred @ 2.7 microns limiting transmission to 2.20 microns limiting its IR transmission.

For IR transmission an infrared grade of quartz is available for transmission to 3 microns and an OH value of typically 10ppm. Fused Silica is resistant to chemicals and high radiation. It had a higher purity to Fused Quartz withstanding temperatures over 1000°C and resistant to thermal shocks. We supply several grades of UV Fused Silica and specifications, low cost commercial applications, spectroscopic, instrument windows and general optical substrates to high precision pressure windows for demanding applications. Precision optical flats are stocked with options of multi-layer AR coatings.

For inquiries or to place an order, please reach out to our dedicated sales team.
