Sapphire Optical Windows
Custom Made
Global Optics supplies custom sapphire 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 repeat production.
Sapphire is used where standard optical glass is not suitable, particularly in high-pressure, abrasive and thermal environments.
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.
