maybe start a new thread? :P i've been looking for fellow laser people near me but have had no luck :/

the one i tested was rather low but i'm not sure if mine was just defective. I picked up a cheap sanwu striker and it started out around 435nm and settled ~440nm doing the full 7.5w. this is the only nubm44-v2 i've had and tested so i'm not sure if this is standard. color looks identically to...

some steal wool does the trick :P

the spectrogard ones are lovely! i briefly had two pairs but it seems they are very rare.. i've only ever seen 4 in existence including the one in your archive... they are great for ion lasers :) did yours have some sort of crud on the back side of the filter? both the ones I got had the same...

pricey but perfect imo :P Voltex supplies are the best.

i gave one to a friend who was meaning to put a 6" orange HeNe into it but i don't think he's gotten around to it. i can ask if he still has it for you if you'd like.

if you find a big old lyte pointer they work great for 6" HeNe hosts. stick a 2 lithium cells in with an voltex A-14-00 and you're good to go.

just wondering if anyone has an omni 543 head with decent life left that they're willing to sell/trade?

how'd you manage to get 594? I've only been able to barely squeeze out 604 but not anything stable.. I believe the prism is only coated for 632.8 and 612 and my OC really only does 632.8.. i have to use a second krypton ion OC on the output to get anything else

one, you'd need an entirely different power supply if you were to do that. two, you'd need a precise gas ratio of about 7:1 HeNe, pure and expensive isotopes of both helium and neon and like said above, a ton of patience. you'd need to smash the outer envelope and water cooling jacket to install...

thats not the proper way to do it. first off, you'll ruin the goggles before your power meter has time to measure them, and the OD increases dramatically as they char.. even at low powers, you won't get an accurate reading. you need a proper spectrophotometer. and i'm guessing this guy doesn't...

well its better than being blind forever :)

they can do good but, theres been some recent tests where the OD below OD3 for OD6 rated goggles and the 15-4 IR goggles dont even reach OD 1 for the MAIN yag wavelength... they can do good but the inconsistency and lies about specs make them untrustworthy. its ultimitely up to you if you want...

survival lasers is kinda sketchy about ratings. some are straight up lies and theres a lot of inconsistency in the coverage. I wouldn't trust my eyes with SL for anything over half a watt never mind 7 watts of 450.. I'd go for OD7 190-532nm from Laserglow...

we appreciate that. now stop digging a hole for yourself. do you know how bad that alt makes you look? why would you bother doing that. it just ruins your reputation more. seriously dude just put down the shovel. the only thing you can really do now is admit you were wrong and take down all the...

also what are we in 2005? That's the worse excuse ever. You literally claimed to not have any connection with Gary in your other account. Even if this were to be true, they spoke exactly like you. You talk about freedom a lot. The way you punctuate and put things in parenthesis, The fact that...

you can't recall their products but you can recall the products YOU sold. its not like you're forced to sell them and you have no will of your own. you are the distributor. You have control of what gets DISTRIBUTED through you. you can recall everything you sold and stop selling them in the...

I honestly do wish he just owned up to it right away and took action. Gary, you are just digging yourself into a deeper hole than you need to be in. I once respected your business since you did sell cheap and apparently good goggles but now, the effort it took to get you to even consider...
