Ophthalmic & Precision Optic Industry
Anti-reflective coating (also called “AR coating” or “anti-glare coating”), is a coating that is applied in vacuum equipment to the surface of a lens by combining materials, generally alternating conductive oxides of different optical refractive indexes. It reduces reflection from the front and back of the lens following the physics laws of Snell, Bragg or reflection and interference (Michelson). The objective of AR coating is to enhance vision, lessen eye strain and improves aesthetics of eyeglasses and eye view.
The latest progress in electron beam technology has allowed the ophthalmic industry to mass produce anti-reflective coated lenses by using new vacuum coating systems to process the typical lenses materials such as mineral glass, allyl glycol carbonate (CR 39), polycarbonate (PC), or other plastics with different refraction indexes. The latest AR coatings used on ophthalmic optics can significantly reduce reflectivity due to the multiple micro layers applied and new materials composition used.
With our broad experience in thin-film technology, at PhotonotExport we offer superior evaporation materials that can be used to achieve the anti-reflective surface and all possible vacuum coating to transform traditional optical lenses into every-day exceptional eyewear.
It is our priority to provide the best quality materials for the world wide Ophthalmic industry ranging anywhere from small independent labs who need a very personal and technical assistance to large lens manufacturing facilities of precision optics or ophthalmic lens with special care in supply chain.
