CaF₂ Optical Windows
Custom Made
Global Optics supplies custom calcium fluoride (CaF₂) 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.
CaF₂ is widely used in optical systems due to its excellent transmission from UV through to infrared, making it particularly suitable for thermal imaging and analysis 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.
