Fused Silica Optical Substrate & Blank for UV / Laser Optics Felix Glass supplies high-purity UV grade fused silica optical glass blanks and finished optical components. Fused silica (amorphous SiO₂) delivers outstanding deep UV transmission, ultra-low thermal expansion coefficient, excellent thermal shock resistance and stable chemical performance. We fabricate custom fused silica windows, plates, domes, lenses and laser substrates with precision polishing and anti-reflection coating options. UV Grade Fused Silica Optical Glass | Low OH Fused silica optical glass is synthetic amorphous silicon dioxide SiO₂, different from common soda-lime glass. UV grade fused silica features controlled low OH content for superior deep UV performance. Typical grades include JGS1, JGS2, JGS3 for different wavelength bands. Material substrate does not equal final performance grade. OH content, bubble & inclusion specification, surface finish and coating determine final optical performance. Interferometer Inspection Precision Polishing Fused Silica Blank All fused silica optical glass is screened for OH content, bubbles, inclusions and transmission. Low-scatter polishing is available for LiDAR and UV laser applications. UV AR coating maximizes transmission for deep UV wavelengths. BBAR broadband coating works for multi-spectrum UV-VIS-NIR systems. Coating must be matched to fused silica substrate and target wavelength range. Learn more about optical coating technology. To generate an accurate quotation within 24 hours, please prepare below information: JGS1: low OH, deep UV; JGS2: standard UV; JGS3: near IR. Select grade based on your operating wavelength. Fused silica has better deep UV transmission and lower cost. Sapphire is harder, better for high pressure and abrasion, but limited UV cut-off. We supply both raw fused silica blanks and fully polished, AR-coated finished components as per your drawing.
