I’m surprised diamonds aren’t used more for lenses. Given its high index of refraction, it seems like an ideal material.
minus-squareBlackmistlinkfedilinkEnglisharrow-up2·2 days agoYeah, the optical quality seems to be the main point. I assume there’s few fields where that level of precision is worth it though. I doubt we’re about to see it on an iPhone any time soon.
