Thank you Paul for the warning, there's a chance I would not notice that without your heads-up. :bowdown:

Yeah I forgot to mention that the batts in 532nm were not fresh but on the 505nm they were. that 532nm eats AAAs in minutes, got to get some rechargeable ones. :thanks:

Hope your mom gets better, I'll pray too.

Nice pics :)

Nice, glad you finally got yours. :) I am thinking of making a slideshow out of 488nm pics, what do you think?

Cheap 589nm will be a big game changer in laser community.

Someone from these forums found them and made a post was it Paul? I don't remember. Here is the link for them: https://www.ebay.com/itm/Adjustable-Desktop-Desk-Table-Top-Tripod-Microphone-Mic-Stand-Holder-With-Clip/272564869129?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 Pretty...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Thank you. :)

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Oh nice catch, I did not notice it. ""375nm and 405nm are key wavelengths in many bio-instrumentation applications..."" Would be awesome if it was actually 375nm.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Can someone explain what this is: https://www.ebay.com/itm/Lasiris-Stocker-Yale-Laser-Magnum-SP-lllb-Wavelenght-400-700nm-Power-500mW-TBX/183135214233?hash=item2aa3b59a99:g:VDAAAOSwH1Var1Ya

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please The sellers often do that, to bait people into bidding more.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Are you getting the one with the housing? The other one seems to remain the same, I'm thinking of snatching it. Oh you meant the 480nm diode, nvm.

Thank you for the offer Paul I'll think about it. :)

Awe nice of you to mention my pics. ^_^ Great review, 60mW is pretty awesome, mine peaked at 55mW.

Glad I did something positive for once. :D Mine is 500 lines/mm, got it from here...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Oooh nice find, I am really tempted to buy it, but I never had modular lasers like that before so I'm not sure how to really work these things. Total in US $ would be around $175, I never bought anything...

Thanks for the feedback guys, I see most of you have already tried this method. :eek:

Not long ago I came across an interesting youtube video about measuring wavelengths of lasers, its fairly recent and I haven't seen a post about it here, so I'm guessing most people don't know about the video or the method the youtuber proposes in it. Here it is...

Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele Yeah its a beautiful host indeed, very heavy for its size and the 488nm color suits it well, mine is stainless steel, I measured it and got 54mW. Thank you for the code. :)
