It's a very long way from putting a 1500mm lens in a pocket camera, but it looks promising. Of course, it could end up being the fusion reactor of optics: always a half decade out.
- dwaltrip 9y agoI've recently gotten into amateur astronomy. The modern high-end telescope eyepieces, usually low-power with a really wide FOV, often now have 7 or more lenses and can weigh 2 pounds. This research looks amazing. It could change the game once again, enabling even higher quality and wider FOVs in a broad range of focal lengths (from what I've read, there has been a lot of improvement in the past few decades already). Probably won't be cheap though.
