TooMuchAbstraction posted:Fun fact: glass is also largely UV-opaque, so you shouldn't sunburn if there's glass in the way! I thought this was true too but apparently not entirely, only blocks the bit that makes you burn, not the bit that gives you cancer. Makes sense otherwise houseplants would die. Metal Geir Skogul posted:Glass is actually IR opaque. However, visible light will still get through, and heat the objects inside. This I did not know. I've done some digging and based on this https://edavies.me.uk/2014/08/ir-myth/ it looks like maybe proper IR what where most of the heat is doesn't get through glass but "near IR" which is what most remote controls use gets through better. So the stuff heating the room is part visible part invisible but what I thought of as IR is indeed blocked. Thanks for updating my knowledge, everyone. SoundMonkey posted:also the "IR doesn't pass through" thing is not reliably true when you're talking about optical glass. i mean most of my lenses even have an IR focus mark in case you're shooting IR. I'm glad I bought optical glass for my projector window then, or my remote wouldn't work so well. Though it seems like there's a big difference between the IR you're talking about for regular cameras vs FLIR cameras. But I'm out of my depth on that, my knowledge is from the geohydrology side rather than the physics.

SoundMonkey posted:the non-smartass answer is "probably ruby or some poo poo" It's not even reliably true for window panes. In the 70's they started treating the glass to reduce the amount of UV and IR light that would pass through them. This improves the insulating qualities of the window but messes with things using IR. A common example is people buying security cameras with built in IR illuminators. They put the camera inside and aim it at the window. Only to look at the video and learn they have a big massive bright spot from the treatments in the glass.

Dark glasses! Twenty miles away, you couldn’t see a drat thing through dark glasses. So I figured the only thing that could really hurt your eyes (bright light can never hurt your eyes) is ultraviolet light. I got behind a truck windshield, because the ultraviolet can’t go through glass, so that would be safe, and so I could see the drat thing.

High end IR lenses in the near and far IR are generally germanium or Zinc Selenide, but holy gently caress are optical purity germanium crystals loving expensive. Near IR and visible can get away we certain kinds of borosilicate glass, or fused quartz, lots of options there. The crappy 'night vision' lenses for security cameras use borosilicate, it's the same poo poo they make pyrex dishes out of.

babyeatingpsychopath posted:Crappy construction for sure: Pyrex labware is still borosilicate, but the dishes are now tempered soda-lime glass after pyrex sold the name to someone. No longer freezer-to-oven safe. Of course, in places that aren't so brand conscious, pyrex is still borosilicate. I got home drunk and hungy one night and instead of cooking pasta in my brownish glass pot I made it in a brownish glass bowl instead and surprisingly enough everything wen't perfectly fine until I poured the finished macaroni out of the bowl into a colander and the bowl shattered into a million loving fragments. The upside is I can't make the same mistake twice no matter how drunk I am because it was my only brown glass bowl big enough to cook pasta in. If I'd poured slower, the macaroni would probably have been a lot less crunchy.

Jerry Cotton posted:Why not just use earthenware (or is it stoneware?) instead? the surface texture of old pyrex is smooth, so its not abrasive to say glasstop ranges or anything as well as the insides so its much easier to clean and totally dishwasher with a steam clean setting safe. it handles rapid cooling and heating really really well and wont do the whole exploding thing.

The old Pyrex was less sensitive to rapid temperature shifts but more sensitive to knocks though iirc, which is why they changed it. But even the old ones definitely couldn't be used on the stovetop, not a surprise that didn't end well!

Blue Footed Booby posted:What are lenses for night vision goggles made of? You're thinking of thermal cameras. The lenses are typically made out of germanium, which is opaque to visible light but transparent to IR. There are a few other materials they use as well, but the principle is the same. Edit: beaten.

I was in a rental house last week, which had a hanging light fixture whose top was somewhere around 5'10" above the floor, positioned in front of a couch such that when you were sitting on the couch, you wouldn't really see it, but you'd absolutely hit your head on the damned thing when you stood up. It got me three times over the course of a week. Bonus: the fixture was loving broken!
