Frequently Asked Questions
Fused silica material has good UV and IR transmission, stability and resistance to thermal shock over large temperature excursions, low thermal expansion, wider thermal operating range, and high laser damage threshold.
The diameter tolerance is +0.0/-0.2mm for general and +0.0/-0.02mm for high precision, while the thickness tolerance is ±0.2mm for general and ±0.005mm for high precision.
The fused silica windows can be uncoated or coated with anti-reflective (AR), high-reflective (HR), partial-reflective (PR) coating, or other coatings upon request.
Fused silica is an optical material formed by the chemical combination of silicon and oxygen. It possesses excellent optical, chemical, and physical properties.
The typical diameters range from 8.0mm to 50.8mm, and the typical thicknesses range from 1.0mm to 6.35mm.
