    Sanwu RGB review

    Work of art. Thanks, I thought it was a one off in that steel. Hell no, I'm not buying the cheaper one either. I want my money more.

    But this one uses Damascus steel.

    DPSS Nonlinear Crystal Types+ my general optics questions.........

    OK, another optics question regarding spinning mirrors, has anyone seen a spinning mirror similar to a polygon with a lot more angles that has slightly differently angled mirrors as it rotates? Starlight Phonics on ebay has one, but I want a lot more facet angles than a polygon has.

    Sharp violet laser diode 1100-1600mw for sale

    Thought I'd add this power testing data to the thread, its resolution is very high, you might need to save it as a file and then resize on your monitor to see the curves on its chart, it overflows my notebook screen by a huge amount...

    90W 905nm Laser Diode for $23

    It's not of much interest to members here, this diode keeps coming up ever now and then, one member even went to the trouble of getting one fired up to discover it didn't even warm anything, much less burn. Average power is a whisper, won't do that, not even warm enough to feel.

    Green laser recommendation?

    If you use a 520 nm laser diode set to 100 milliwatts or less and then expanded to five inches, that might not blind them, you would need to determine the power density when expanded that far at distances, but with that big of a lens, there wouldn't be much divergence so it would go a long way...

    WTB yellow dpss handheld or lab

    I didn't know about the 575 nm failures until recently, why for?

    Videos you wish to share part two.

    Well, I tend to agree on that myself, but he obviously either doesn't care, or just wants more hits to his YT channel, probably both. Y_9vd4HWlVA

    Best Burning laser

    All I need to do is scan down their offerings, and having known what the normal prices are for the same thing.

    I don't agree.

    DPSS Nonlinear Crystal Types+ my general optics questions.........

    Guys, Could someone kindly give me some input on what Type 0, I and II means in practical terms for DPSS crystals. I've attached a PDF of a web page I found online. Can you convert this precise detailed information provided in the attached document into rules of thumb general understanding for...

    Best Burning laser

    Laser pointer pro charges FAR more for the same thing than anyone else with very few exceptions that's what is wrong with them, a rip off. Seems this Thor H 2 isn't very far out of line though, that is the one exception I've seen where they only charge 20% more for that than other sellers on...

    Guy points green laser pointer at guy with camera

    I wouldn't like having someone come in and harass me with a camera, legal or not.

    Best Burning laser

    The NUBM44 450 nm blue laser diode is probably the most bang for the buck you can get for quick burning. Having something made custom with one of those using a pair of cylinder lenses to correct the beam shape makes this diode burn far better than without it, but I'd also use a much larger...

    That guy pointing the laser was also being one.

    I had the same impression, that guy recording people there was being a major dick.

    My new TI-V2 host with Tritium

    Be careful what you wish for, I could do that, he made five of them for me.

    My new TI-V2 host with Tritium

    3 each 36650 batteries, and instead of 70 mm diameter head like this one, 100 mm OD and 30 mm longer inside chamber.

    Oh, sorry, I wanted it free. What I really would like is a larger version of this one you built for me:
