Refractive indexformula

AGC has successfully developed glass substrates for AR/MR glasses and established a mass production system for them. AGC's high refractive index glass substrates feature high refractive index, high transmittance, high flatness and surface smoothness.

Recent advancement in wearable displays transforms everyday life, working environment, shopping experiences with augmented reality. AR glasses are emerging hardware for AR experiences with see-through display which overlays virtual images to mix real and digital world (aka mixed reality). As AR glasses give digital information to users as shown in the Figure above, the market is expected to grow like smartphone.

FLIR IR Windows add a barrier between you and energized equipment, protecting you from arc flash accidents. IR windows are easy to install, easy to use, and will help you work with greater confidence. You’ll perform inspections more efficiently and reduce the threat of arc flash injury, all while staying in compliance with NFPA 70E requirements. Choose the anodized aluminum frame, or opt for durable stainless steel to prevent mixed metal issues.

AGC's high refractive index glass substrates feature all the characteristics required for large Field of View and high image quality for glass substrates used in next-generation displays.

FLIR IR Windows' broadband crystal lenses transmit short, mid, and longwave IR while also allowing illumination to shine through.

Refractive index of glass

Appendix - By increasing refractive index of glass, light can propagate at larger critical angle by TIR (total internal reflection). This means image can be input at wider incident angle (i.e. large original image area) – see left Figure below. Also, by having a large output DOE area, it makes possible to have more tolerance against eye position movement – see right Figure below. For these reasons, high refractive index and large DOE area can support more natural visions for users providing real AR experiences.

Choose the standard anti-corrosion anodized aluminum frame, or if there are mixed-metal concerns, opt for durable stainless steel.

So far, AGC have provided various products in this market such as glass packaging substrates and optical components, and now we are ready for production of high refractive index glass substrates after years of R&D efforts.Because AR images propagate inside the glass by TIR, the glass material needs to have high refractive index (large FOV) and low propagation loss (see Appendix). Also equally important are glass processing technologies to enable very flat and smooth surface. Our newly developed high refractive index meets all these requirements. We will launch large volume manufacturing facilities in Japan, and plans to expand production to support emerging applications as well as AR glasses & head-up display markets.
