Name: Factory Custom Corning 7980 UV Grade Fused Silica Plano Concave Lens
Brand: Henan UM Optics Ltd
Availability: InStock

Description

UV Grade Fused Silica is a high-purity synthetic amorphous silica (SiO₂) manufactured via flame hydrolysis, delivering exceptional optical performance across the deep ultraviolet (DUV) to near-infrared (NIR) spectrum. Engineered for precision applications, it offers ultra-low thermal expansion, minimal fluorescence, and high laser damage resistance—outperforming crystalline quartz in stability and transmission consistency. Ideal for demanding UV laser, semiconductor, and precision optical systems, it is available in custom sizes, grades, and coatings to meet strict project requirements.

Frequently Asked Questions

What is the key difference between UV Grade Fused Silica and natural fused quartz?

UV Grade Fused Silica is synthetic (flame hydrolysis) with ultra-high purity and DUV transmission; natural fused quartz has higher impurities and poorer UV transmittance, making it unsuitable for deep UV applications.

What are the thermal operating limits of UV Grade Fused Silica?

It maintains stability from cryogenic temperatures to continuous use at 1000°C, with ultra-low thermal expansion to prevent thermal shock.

Can you provide custom-sized UV Grade Fused Silica components?

Yes. We offer custom windows, lenses, prisms, and substrates in round/rectangular geometries with tight tolerances.
