Felix Glass Co., Limited manufactures custom sapphire optical windows for teams that need controlled geometry, optical surface quality, durable exposed surfaces and documented inspection requirements. Projects are reviewed against the working wavelength, crystal orientation, sealing design, environment and purchasing specification before quotation. We fabricate sapphire windows strictly following customer CAD drawings and dimension drawings. From simple round blanks to complex contoured outlines, each component goes through grinding, fine polishing, cleaning and metrology inspection before shipment. Suitable for scenarios where off‑the‑shelf optical parts cannot match assembly or environmental constraints. Take a quick tour inside Felix Glass optical production workshop, covering CNC machining, polishing, coating and precision inspection procedures. Felix Glass supplies custom subsea sapphire viewports to North American marine robotics manufacturers for ROV underwater inspection cameras. Our sapphire windows successfully passed continuous salt fog and high‑pressure cycling tests, significantly extending the service life of subsea imaging equipment. Submit your drawing, wavelength requirement, crystal orientation and operating‑environment details. Our optical engineers will review your custom sapphire window specification and return formal quotation.Drawing‑Based Sapphire Windows for Demanding Optical Systems
