Re: 1-1.2 watt 445nm lasers CHEAP $180 Ahem. Smells like FDA/CDRH. :whistle:

Contrary to what Trevor's said, DHOM (the only optics manufacturer in Suzhou that uses that design of driver/head, is a very respectable, if not-so-well-known company. This is their website: ?????????????? Click the English button. This is their (very small) eBay store (even Viasho has one...

Now, I know many of you have been looking for them, seeing as AixiZ and O-Like only carry the half-threaded versions. I was going through the Rayfoss site today, and found these: 2pcs 405nm/445nm Collimation Optical Lens www.rayfoss.com It's a three-element lens, like the AixZ glass for...

Re: NJG-18, 3 mode driver for 445nm with single cell Nice build, but just a quick question about the heatsinking- why is the inductor heatsinked, but the semiconductors not? In the driver, the semiconductors are responsible for the majority of the heat generated. The coil shouldn't be getting...

As enigmahack stated earlier, it really needs to be tested before you can determine whether it really is worth $880. However, for a lab/lightshow unit, other factors are important as well. It's not simply all about output power: -Output power (the most obvious) -Output stability (whether the...

The half-threaded O-Like lenses are perhaps the best choice at the moment for a balance of power and beam specs. Yes, the splash might not be bad when compared to the 405-G-1 (which, being a SFL single-element lens, picks up anything and everything), but it's still a pretty trashy beam profile...

This is by no means settled and by no means passable either. If there's that much artifacting around the beam, then there's clearly either a diode or lens defect. In all of the 445s I've seen (One using an AixiZ full threaded glass, one using an AixZ half-threaded, one using an AixiZ acrylic...

John, In reference to your signature and the $885 1W laser 'pointer'- I don't know if anyone else has told you, or whether I'm the first to mention it. That isn't a laser pointer, it's a 'lab' laser, commonly found in either a lab (unlikely, considering the model and power supply), or in laser...

Anyway, thanks for the feedback. This project is now in the dustbin since I ran over the whole contraption with a chair. Oops, it won't be missed. :scowl: Also, using speakers with more travel (and using a MUCH bigger amp) would be a good idea. I ended up using boiling water to de-stick the...

LOL. My hot glue gun drools as well, and it makes a mess. Some of the spider-web thingys got sucked into the labby driver's fan. I'm surprised it ran for four full minutes without a fan without overheating. On a side note, I need to work out how to get hot glue out of carpet.

So, I got bored, and that's never, ever, ever a good thing. :can: I went out and bought a set of $1.50 headphones, and attacked them with a hot glue gun and screwdriver, and glued a few FSRs to them. To top it all off I pointed a 150mW labby at the whole mess (because that was the only laser I...

Do you want a banner advertising everything CNI makes, or do you want it for the GLP-589 only?

Going by the articles I've seen, RTP is a Q-Switch crystal, not a doubling medium. Also, there's still the wavelength issue. Although it might only be off by a a single nanometer, it means you're losing massive amounts of efficiency. By some black magic (as seen on the Laser FAQ), KTP will...

The labbies are here: 473 nm Blue Laser, DPSS, B&W Tek BWB-10-OEM - eBay (item 220660063507 end time Jan-22-11 14:47:07 PST) Also, I'd just like to point out that aligning the 808 is the least of your concerns here. Because 473nm uses Nd:YAG instead of Nd:YVO4, pump wavelength is even more...

OK, there's no stopping the reanimation of this zombie thread now :san: Anyway, the PHR has a very (short of buying a commercial dichro) efficient beam combiner. It's the largest optic in the sled, and it's the one responsible for bouncing the red and violet beams into the objective lens. It's...

Actually, it's meant to be like that. These diodes are case negative, meaning that the negative contact of the diode goes straight to the case of the diode. Any damage would be to the die itself, and not visible without a microscope.

Somewhat correct on both counts. Antistatic foam is the black stuff. This foam is conductive, and actively protects against ESD damage. Silvered or specially-marked black plastic is also conductive and protects against ESD. Pink foam and pink plastic is non-conductive, however, it is not...

Prototype, you'd be correct on that one. If it's actually a Gen III nightvision system it shouldn't have any infrared LEDs. These aren't your CoDMW2 'nightvision goggle' appendages. These nightvision systems don't work by illuminating with IR, instead, they pick up existing light and intensify...

So, this question's been asked one too many times, and most of the time the forum search function doesn't work properly either, and these answers get lost. I'm going to try and get a sticky for this thread too, if that isn't too much to ask for. Why is my green laser only putting out red...
