High-Precision Fused Silica Discs for Specialised Applications

noe-glass-discs-1013979736-1

Our UV Fused silica discs have no flourescence and high transmission in the DUV, UV and IR ranges from 180nm to 2000nm. Our optical grade fused silica is virtually bubble free and resistant to chemical and thermal shock. Manufactured to tight tolerances, they are ideal for a variety of specialised fields, including precision optics, laser components and more. Their low thermal expansion and excellent transparency, make it perfect for both routine and advanced technical applications. Our fused silica discs are available in a range of standard sizes to support a wide range of requirements as well as custom made to your specification.

Due to its low co-efficient of thermal expansion, low refractive index and high transmission, fused silica is well suited use in precision optical flat discs. Also being chlorine-free results in outstanding resistance to laser damage. We can offer custom optical coatings to all products.

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