I used to work as a researcher at various different unis and one always takes it for granted (well almost) that one doesn't pay personally for all of the research gear. Now I work for myself and being able to know where to get ones hands onto "cheap scientific gear" is a must LOL!

I cooked the green coating off of my 1-inch optic glass "X CUBE" with a 1000 MW ( 1 WATT ) 450 nm class IV LASER, it has burn marks only on the green coated side

So, I have a 25 mm cube from an NEC projector. Mounted in an aluminum frame. Need advise on how to remove the aluminum without hurting the cube. Plan to facet the cube.

Facet the cube? Is there any particular reason? Sounds like an interesting project… But keep in mind Most of the coatings are on the exterior. Technically it’s 4 triangular prisms glued together. I guess that’s why they call it a “X-cube”… because when you look down from the top you can clearly see the separate pieces of glass. Some of the coatings go through the interior of the cube… But they won’t really be visible once you cut away the face. Just a tiny little cross-section of coating a few microns wide. Sounds like a fun project regardless. I’d Be interested to hear if you have any updates on this project? I’ve done quite a bit of faceting myself, but that’s been years ago. Last machine I had was a facetron… When they first came out with the really fancy version… So that shows you how long ago it’s been since I’ve cut anything, Except the line in the grocery store.😂 I also enjoy restoring faceting machines. vintage and modern machines… Like the graves Mark four and Mark five XL, old ultra tec, lee, and others… My skillset is best suited for things like that. Equipment restoration and calibration. I’m not very good at being creative, or spontaneous. And that’s important when cutting gens. Although at first it’s important to follow the math and the long established designs… After you’ve cut a few hundred or thousand stones… Do you want to start playing a bit… And coming up with your own designs. And that’s not something I’m good at. I’m good at working to a design… Following a complex blueprint no matter how long it takes. I could probably build a working nuclear reactor in my lab… If I had the plans. (not bragging because A regular 12 year old can do the same thing😂) But I’m not smart enough to design and innovate. I just have to trust the engineers who made the blueprints… And let the folks with the higher IQs have fun with innovation and creativity. But I still enjoy being part of the craft…… But instead of doing the cutting…I’m buying high-quality machines from the 60s, 70s, 80s, and even some modern machines……Completely tearing them down and sand blasting them to the bare castings. Then restoring and calibrating them to perfection. To a much higher tolerance and accuracy than when they left the factory. (which really is overkill… because the manufacturers did an incredible job…But it’s something I enjoy.)i use more modern materials and coatings…so that things won’t wear out and will last forever. I’m a machinist by trade, but do woodworking and electronics for a living. Two separate businesses. I have an electronics lab, and my main business is component level circuit board repair….. for a wide range of industrial and government clients. Also a bit of metrology and optical test equipment calibration. (spectrometry and such) and that’s how I became interested in lasers and optics. It’s a golden age of equipment! If you know where to look you can get an entire professional optics laboratory complete with lasers, an optical breadboard, and all of the equipment. For pennies on the dollar! government auctions, auctions at colleges and elsewhere in academia, and Ebay are your friend! I’ve spent a very small amount of money… To amass the type of equipment I have. Buying decommissioned laser equipment and optical lots from government and industrial auctions. At least $50,000 worth of optical equipment if I had to buy it new. And I paid less than 10% of that. Way less! Some pieces were bought individually… But a lot of it was purchased in several lots that would be auctioned off all at once. Pallets full of stuff… For pennies on the dollar. And you know how the government in large corporations work… They buy stuff they don’t even use. So a lot of the stuff was either brand new or like new! Sorry didn’t mean to ramble on. Would love to hear any updates about your faceting adventures.

I have one of those X-cubes that just today I pulled off all this metal that was stuck to the cube and oh boy it was really stuck on there!! like the first thing to come off with this plastic bit with a little prying and then I pried in between two of the metal parts and one came off with left two on ether side, now I tried prying it off from the top but it just split in half and I later found out that there was glass in the metal bits so I had to be carful other wise I would get broken glass everywhere, finally I used some broken flat head which was really small to get into the little holes on the side and that finally pried off the two remaining metal bits off the cube and oh boy... was it worth it? I don't really even know anymore :/

1mw or 1w ? The 1w green lasers I have purchased are usually around 80 -200 mw and the 1-5 mw lasers are actually around 20mw. Have you seen one in my videos ? I will be happy to put it into a new video.

Go on eBay and type in “projector”…. And then filter the results by, lowest price, buy it now listings only, and used items instead of new. You can pick up plenty of projectors between $10 and $30 including shipping… The one he took apart in this video was an LCD projector. That used a bulb/lamp as it’s light source… They’re very common. And you will see written on the top of the projector a little emblem that it says something like “3 lcd” or “LCD 3 technology“. It can either be bulb, LED, or laser illuminated. It will still have optical components like he showed in this video. Or it may vary a bit. Before you purchase it, get the model number and type it in on Google to try and find a photograph of the inside optics. That way you can see if it’s got what you want before you buy. But most all of them will have an Xcube inside. But be careful. If you get a working projector, it can blind you in seconds. Don’t look into the light source. Doesn’t matter if it’s a bulb, LED, or LASER!! Yes…some of them are even lasers… All of them will damage your eyes but obviously the laser projectors are the most dangerous. Casio made several types… that you can usually find in working condition for under $50. I’ve purchased untested units as cheaply as $20. Even if the lasers are all fried… You still get a shit load of incredible optic parts! Which were designed to be used with lasers. So they’re more practical for laser experiments sometimes. They have a big array of individual laser diode’s inside. Blue diode‘s… you can find videos on KZitem and plenty of pictures on Google. Just be really careful… and don’t mess with them until you’ve researched how to properly power up the lasers. Laser diode‘s are the most sensitive electronic component you’ve ever messed with! Even a bit of static electricity from your body can blow them and ruin them completely without you knowing it. Even if it’s a small amount of static, and you don’t even notice it A single low power diode could blind you faster than the human eye can blink. Even from a simple reflection off of a shiny object in the room. Or one of the optical components inside. A small reflection is all it takes. It might not totally blind you… But you’ll start to notice a blind spot in your eye over the next few weeks. And it will never go away. A little spot on the back of your eye, and no matter what you’re looking at in light or dark they’ll always be a missing segment of it. Like a television with missing or blown pixels. Got to laserpointerforum.com for more laser information. Plenty of great optics information on there as well!! Also “Sams laser faq” is a great website. On KZitem, subscribe to zenodilodon, And watch some of his videos before messing with any type of laser or experiment. He approaches it with a real scientific method… It is a genuinely cool and nice guy who is super smart. Styro-Pyro makes laser videos also… And talks a lot about safety. Listen to him when he emphasizes how easy it is to damage your eyes permanently. don’t get me wrong…He’s a really smart and funny dude. I’m just not a huge fan of The types of videos he puts on KZitem. There’s nothing wrong with them… I just prefer more scientific content instead of burning shit… that’s just my preference is all. He’s SUPER smart and knows what he’s doing and is well respected in the laser community. There are plenty of other great KZitemrs with laser content as well. Just be careful, and take the time to order a pair of laser safety glasses from Amazon. The cheap ones are better than nothing… But you still have to be careful. Watch KZitemrs who have tested the safety of cheap laser glasses. There are several videos. if you buy a $5-10 pair of cheapos… look at reviews or test them yourself to Be sure they will actually keep you safe… but even if you have $100 pair… You still obviously want to avoid the beam shining in your eyes no matter what. Hope this helps someone
