Nippon Electric Glass Co Ltd has developed a glass substrate that it calls “invisible glass” which allows about 99.5% of incoming light to pass through it, reflecting only about 0.5% of the light. Compare this to a normal glass substrate where about 92% of incoming light passes through it, and the rest 8% of the light is reflected off it. The result is that you cannot tell whether there is a glass in front of you or not since the reflection is so minimal.
Hopefully, we should soon see this being used in the LCD of cameras so that viewing it in bright light won’t be a problem anymore. Its use on doors would require warning stickers on the glass so people don’t walk right through them.
