UV Fused Silica Windows
UV fused silica windows is a high performance optical windows made from UV-grade fused silica. Coligh manufactures diameter <1000mm high precision uv fused silica windows in various shape types also provide thin film coating service.
- Coligh can customize any shape according to customer requirements
- Size <1000mm
- Uncoated windows can be provided
- Coatings can include UV film, VIS film, NIR film, SWIR film
- Thin film coating can include AR film, high reflection film, spectroscopic film, etc.
Optical UV Fused Silica Windows Description
UV fused silica windows are often used as protective windows for electronic sensors or environmental detectors. Coligh produces a variety of uncoated and coated UV fused silica windows. We receive a variety of custom requests and can provide customers with any shape processing, as long as the size is less than 1000mm.
In addition to providing uncoated windows, we can also process coatings according to customer needs. Our current standard fused silica windows are processed with four anti-reflection coatings
- EUV thin film AR coating Ravg<0.5%@10–121 nm（Custom）
- UV thin film AR coating Ravg<0.5%@250-425nm
- VIS thin film AR coating Ravg<0.5%@350-700nm
- NIR thin film AR coating Ravg<0.5%@600-1100nm
- SWIR thin film AR coating Ravg<0.5%@900-1700nm.
The UV fused silica windows produced by Coligh have the following characteristics:
- High precision: The transmitted image will not be distorted, and the laser shape can remain unchanged
- The beam propagation angle remains unchanged
- The optical magnification factor through the window remains unchanged
- High transmittance and high anti-reflectivity

UV Fused Silica Applications
UV fused silica has been widely used in many high-tech fields due to its excellent optical properties and physical and chemical stability.
- Laser field：In laser processing equipment and molecular lasers, as an output window or protective lens, it can withstand high-intensity UV lasers and avoid thermal deformation
- Semiconductors and lithography ：In DUV lithography, UV fused silica windows can be used as protective windows for lenses
- Industrial applications：In UV curing systems and environmental testing, it can be used as a protective window to maintain optical properties
- Scientific research and aerospace：Ultraviolet detector windows for synchrotron beamlines or space telescopes to resist high-energy radiation and vacuum environments
