    445nm Firefly

    Get an AIXIZ module on eBay and use it. I do not know about the machining of this module you are using. There is a front and back focal length.. Unsure of what lens was used and it's characteristics. I do not know if anyone else has had these problems. AIXIZ is cheap and made relatively well.

    Yup, I agree. Still unless a small cylinder lens is used right over the laser facet (with can opened, patented btw), it is hard to get a square beam which when focused will look KIND OF ROUND.. Company I had done some work with. See information on their "uLens" Blue Sky Research - Products...

    445nm Firefly

    OK, fair enough...Call / e-mail the seller and ask him if this is the beam profile he would expect from the module/heat sink/lens combo you purchased. Most people on this forum are using Aixiz parts with little or no problem, or th ey are making them themselves. It sounds like a big enough heat...

    It looks like th beam is being clipped by the lens aperture. Most of the 445nm lasers I have, the fast axis is longer than the one in your photo. Where did you get that housing? Doesn't look like enough heat dissipation for this type diode...

    445nm Firefly

    Laser diodes project an odd "tire track" shaped beam when they are damaged. It would look like a stripe along the fast axis of the laser diodes pattern on a wall with or without the lens at 10-20', less without lens. I'm not sure where you obtained that housing. I also not sure how the laser...

    This may be the wrong focal length lens in housing, the diode may be dying or being optically clipped by the small aperture.

    445nm Firefly

    This laser has a very fast axis and slow axis. It will always emit a "stripe" rather than a DOT or Gaussian type beam. 2 ways to correct this, anamorphic prism pair, or perfect cylinder lens mounted below focusing lens to slow down fast axis (LONG PART OF BEAM) This is a problem for bar lasers...

    It looks to me after an exhaustive search of off-the-shelf units, I may have to go to China or Taiwan to get what we need. Jay, could you fit it into a pill? Still thermal sheets and thermal epoxy may be better in some hosts. I will keep looking. The smallest I found was 10mm x 10mm...

    I have used the arctic alumina epoxy for years, was a distributor. Here are some photos of the heat sinks... before the thermal epoxy. Just need to get it to fit right into a particular host

    Re: FS: 600mW, 445nm DORSY Host w/ 2x 16340 batts / charger It is a DORSY host, laser into Dave's heatsink, with Flex V5 driver & Aixiz New lens. SO the diode actually press fits into daves heatsink, it does not use an Aixiz module

    SOLD, thanks FS: a 600mW, 445nm DORSY Host w/ 2x 16340 batts / charger. Asking $175 (REDUCED PRICE) Nice unit. I guess if you wish you could jack the power up to 900-1000mA. The battery life is better with it at 600mW. It uses Aixiz newer lens, Dave's Build heat sink and Flex V5. Nice unit...
