HOYA established optical glass melting and production in 1941 and has evolved into a renowned global manufacturer of custom optical materials and components. HOYA’s material portfolio includes optical glasses, coloured glasses, and anodic bonding glasses, in addition to polarisers and specialty materials.
Production capabilities and processes support the manufacture of coloured glass filters, coated filters, machined, pressed, and moulded blanks, finished lenses, flats, and optical elements, aspheres, and other components utilising HOYA’s material portfolio.
Through our vast and experienced global supply chain, HOYA is able to support aerospace, biomedical, consumer electronics, semiconductor, telecommunications, automotive, LiDAR, and other optics and photonics applications in Asia, the Americas, and Europe.
We provide coloured glass filters for a wide range of applications such as cameras, optical instruments, physics and chemistry, educational materials, industrial and medical instruments, with spectral characteristics and size according to your requirements. The coloured glass filters can be supplied either polished at 50x50x2.5 mm³ dimensions, unpolished at 165x165x(3…9) mm³ dimensions or according to our customers’ requirements with a thickness as low as 0.3 mm.
HOYA also offers a wide range of different coatings:
New infrared transmission optical filters can be used with a 1550 nm light source instead of a conventional 900 nm one. The 1550 nm light source is not subject to the output limits of IEC recommendations for eye protection because it is outside the apparent light range. You can get a better S/N performance even under sunlight because the intensity of solar radiation around 1550 nm is very weak.
