I have a tangerine orange HeNe (612nm) but again they are very rare and IF you can find one, it will cost in excess of $500. it will be less than 5mw though. :) For a HeNe talk to Sam Goldwasser of Sam's Laser Bible https://www.repairfaq.org/sam/lasersam.htm

thanks for the pics looks like a load of fun. ;)

This is just an opinion, but if you are having trouble with finding info, Going to a LEM would be super helpful for you. You would get to see many projectors from the home built to professional, firsthand (Once Covid-19 dies down) At last years SELEM, Mariomaster had a homebrew laser projector...

Ran across these a few years ago, only problem with most of these is the rechargeable battery, IMO I finally found a plasma lighter that uses a removable standard replaceable 14500. It has a double arc, very nice and now it can last forever as I can just swap in another battery Can't find a...

Yes but the average firearm isn't kept loaded and then fired repeatedly in a living room while being waved around by a 14 year old

Principle regarding Group Buys Matt 5:37

I have a 3x Beam Expander from them No issues on getting it. Plus lots of people here have purchased from them and I haven't heard any major issues, although they are a newer company.

thanks It'll take at least a couple months to get back to normal PAID and Address sent

In any case, somebody is spending tons of money to fill the gap. That is good new either way. Medical seems to be the push and there is money in it. So IMHO, it will happen when enough money and "ambition" get directed that way. Yellow or Orange diodes - either way I'd be happy.

Will the 10x BE screw on a standard aixis head like the Sanwu 3x does? Didn't look like it from the pics

You are also not stuck on a 18650, they are common but if you really want you can fit two 18350 or 16340 in almost the same space to get the higher voltage, if that helps at all. Works in most portables (65 mm vs 70 or 68mm) Last three digets are the length - ie: 650 is 65 mm etc

Confirmed - just got back on Missed this as I was in hosptial for 3 weeks. What about payment - please send info,

Another possible option is that several members, including me, bought Kenometers a few years ago. They have the same Ophir head on them and most were priced less than the head is going for now. You might find someone willing to part with theirs (but not me) At the time, the heads were available...

Thanks, nothing listed on forums regarding them. But Meredith Instruments has a laser Penta Prism for sale on ebay. I wondered why you would use one and obviously if no one has ever posted anything about them on here or PL then they aren't very common in laser systems. Apparently they are...

Can anyone explain, in simple terms, what a penta prism is and how it is used? I read the specs but I'm apparently still not sure of the way it works.

I like my Kvant Clubmax. Kvant sells modules also but they are pricey. I just had someone build me a projector for my house, only one watt, but Saturn scanners, single mode, PBS cubed on all three colors, perfect alignment. Best you can get without going to gas and super professional. He is on...

I have bought a couple similar ones to play with. One was 1/2 watt other was slightly more. My biggest issue with them was the size of the beams in relation to each other. Alignment was decent for short distances, Nothing great. On the ones I have, some of the beams where MUCH larger so you...

Nice, but out of my range :(

Thank to all of you for the hard work.

I wondered what you meant by "proper lens" These things are always bad IMO.
