Fused Silica Optical Windows
Custom Made
Global Optics supplies custom fused silica optical windows manufactured exactly to customer drawings and specifications.
With no minimum order quantity and full UK inspection, we support everything from one-off prototypes to production supply.
Fused silica is widely used in precision optical systems due to its excellent optical clarity, low thermal expansion and strong performance in UV and laser applications
Typical response time: within 24–48 hours depending on specification.
All components are inspected in the UK prior to dispatch to ensure they meet specification.
