Thanks guys, but I already have a 2x and two 3x from OPT lasers. What is left for me to try is a 12x combination so I can rest my wandering brain and crank the power finally to max :-) thanks

Hi, Are these still available? looking for a set to continue testing combinations for best NUBM44 beam. Let me know if anyone has one for sale. Thanks

interesting, But measuring the line length is tricky, and varies depending on the glow of the dot, and what you actually decide to measure. What power are you set to output when doing these tests? Do you know the difference between G1 and G2 lens when it comes to NUBM44, or in general. Is...

Hi guys, I bought some great lenses from Mateusz from OPT Lasers. They are all 12x12mm so very easy to build assembly for. Results are great!! I have been finally doing some more tests with these cylindric lenses and NUBM44 diode. I have one 2x, two 3x lenses which I'm using together in...

nice build and a fine review!!

Thanks I'm getting solid 1.0 mrad beam after some more tweaking of the two 3x lenses and the plano-convex. I remember my RPL425 had 1.0 mrad beam :-) This is not bad at all for a multimode 6W+ diode. But does it get even better though? :-) I might be crazy though, but I'm thinking that...

Thanks Alaskan. I didn't manage to post images before you replied, but they are above now. I got the lenses a while ago. Actually, mine are also 12mmx12mm from OPT Lasers company. Mitsubishi Oclaro laser cylinder anamorphic. I started with a single anamprphic 3x and a corrective plano...

I've been battling the "stripe" of the NUMB44 diode out of the G2 lens as well as the standard three element glass lens. I think i will end up setting up corrective lenses for both focusing lenses so I can make a final choice once the full power is on. I'm working at the reduced power of about...

The fan noise is very low and "warm" sounding. Kind of like a laptop at its lowest. It is only engaged when switch is in "constant ON " position. The air flow is a breeze enough to push a small feather around the table in front of the laser's exhaust holes. I choose lowest noise fan. Holes are...

Re: 6.5W -> 4.5W 450nm Cypreus IIIb reloaded with adapted 355nm Linos Beam Expander Cool setup, and quite a successful one! Congrats. Have you measured the beam diameter at the output of the beam expander, or the beam divergence? Any pics of the projected dot at range would be nice to see...

Very interesting. Nice job man. I can totally relate to building laser projects during lunch hour at work :-)!!

thanks a lot crazyspaz. I've been thinking of how best to implement those cylindric lenses for some time now. It was time for action :-) pic coming very soon. I'm expecting anywhere between 5x to 8x power per area at distance x over the previous M140 setup. HAPPY NEW YEAR!!

Time for a long awaited major upgrade guys! Stingray 3.1 coming very soon. new NUBM44 diode + new lens assembly for much improved beam quality and range. So far tests are showing under 1.14mrad beam with G1 lens and showing definite potential for better than 1.0 millirad!! will post some...

Re: Pocket LPM Coherent LaserCheck - $170! - Great Condition ! sold!

Re: Pocket LPM Coherent LaserCheck - $170! - Great Condition ! I know they sell them on eBay for $180 and up. Many of them are not calibrated well across the visible range at all though, specially older units. I had two, and the first one was only good in 650nm range - thats it. Coherent...

Re: Pocket LPM Coherent LaserCheck - Half Price ! - Great Condition ! Still available. Let me know guys if you have any questions about it. Its a good price and a nice pocket size laser power meter for quick checks. I can lower the price if you have reasonable offer.

Re: Coherent LaserCheck - Half Price ! - Great Condition ! If you are interested, contact me, I may adjust the price.

never contacted admin first before. Since when is this a rule?

whats up with Buy,sale, trade? How long is it normal to wait after you post a new thread nowdays? 24h? It took few days last time i did it and i thought it was not happening so i made new post and that second one showed up within 12h before the first one?

I'm selling my Prtable LaserCheck by Coherent. Its served me plenty, and its a nice unit to have if you own few lasers 1W and below. The only bad thing about it is that it is not calibrated for blue and violet lasers well, so for 445nm laser you need to use 421 setting. It is not good for...
