    515 nm Osram versus DPSS 532nm beam Quality ?

    People talk about DPSS having better beam quality than direct diode but I am comparing a 5mw DPSS with UV Filter to the Osram 515nm at 5mw . Both supposedly have a 1.1 mm beam so not a square elliptical etc on the Osram ? These are waterproof CR 123 Lasers with APC and glass lenses constant...

    Laserto and Hilasers 460 nm Lasers °○°○° ?

    Laserto and Hilasers... Both seem to sell 460nm Blues at 1 mw 5mw 20mw and 50mw. Unfortunately they are "Pen " Style Lasers. I asked Laserto if they will make a CR123 or Li- ion 16340 type Host with 460 nm. Is 460nm a big difference in brightness and Color from 450nm ? One Site says...

    Direct Diode Lasers in Various Colors in 2 different Power Levels

    I wonder if there is interest in getting Lasers in various Colors in the fairly inexpensive Wavelengths ? Nichia makes a lot of Blues and of course we have Osram 515nm and there is a Japanese 635nm which is fairly inexpensive. We may be able to set up a Group Buy where there is a number of...

    New SUPERBRIGHT Direct Diode Laser

    18650 Rechargeable Lasers Rated at 5 milliwatts(?)

    I am thinking of getting a 5 to 10 milliwatt Laser in Green to have visible beam and would like a 18650 because my regular LEDs use them. But it occurs to me that many Chinese Manufacturers are slapping the 5 milliwatt label on there ...but is it unlikely that a focus laser using 18650 would be...

    Green Power Safety Questions

    So if you want to play around without goggles reflecting off walls etc. with a green laser- do you want to use a 5 mw or maybe 10 ? Obviously, reflections could get dangerous at a certain point, provided there's no mirrors, what's the cutoff in milliwatts ? Some have remarked that looking at...

    Modding 30-40mw green DOWN to 10 or 15

    I want a low power Green 10- 15 milliwatt that uses torch or flashlight style and with rechargeable batteries and clicky switch and IR filter. It occurred to me that maybe I could get TWO cheap units and send BOTH to one of you MOD wizards and you could MOD one for me and install IR filter and...

    Questions about Laser Led/ Flashlight Combo

    Sold at NAPA Auto is a nice little LED/ Red Laser flashlight rated at less than 5 mw but a great little laser for playing with your cat. 7 dollars and in a very sturdy aluminum host. I wish it was a green Laser because at this power a green might be bright enough to see the beam itself- the...

    True 10 mw with IR filter safe without Goggles ?

    IF I had a verified NON overspec 10 mw green made with an IR filter, would this be safe for careful home use without goggles OR would it actually have to be 5 mw, then I might not see the beam. IF I have to wear goggles anyway, might as well get a more powerful one but don't think I could...

    Questions about cheap greenies

    Take a look at the links at the bottom of the page of two different units rated at 100 milliwatts and 200 milliwatts- one is supposedly available at abot 24$ and another about 45$.I wanted to get opinions on a few cheap green Lasers, a few of which are hybrids, with an LED Flashlight and a 5 mw...

    Cheap 100 and 150 MilliwattGreens @ Tmart

    New Guy on Forum-Are these for real at only 20 dollars or so I'm seeing 100milliwatt green lasers and at about 40- 60 dollars or so there are a few 150 mw units listed and even 200 mw for a few dollars more. Some of the "reviews " are misplaced so it appears someone is using a 100 or 150mw...

    Strength required to see green beam at night

    Was thinking of getting a green laser to play around with carefully and legally , of course, and noticed one on Ebay, claiming to be "military" grade uses the lithium battery, but says only 5 milliwatts. Guessing that since it says you can "see" the actual beam, it's really more powerful- it's...
