Just be sure your compressor has a good filter on it. If it's an oil lubricated compressor you can get some of that junk on your optics. It could also potentially blow metal (or other material) dust at your optics at high velocity.

As RedCowboy suggests, there are some towlettes that can be purchased from photo stores or online. Just note the ingredient list for things that are safe for optics. A clean, high quality microfiber cloth is also pretty good for this. I use Kimwipes in the lab for optical instruments. They don't...

I'd go for a 473nm DPSS. I don't have that wavelength in my collection anymore. The CR2 host isn't my favorite but I guess that's what's available. Of course, as others point out, that depends on disposable income and cost.

If you want something more powerful than 200 mW of green light, its probably not actually 200 mW or you want something that really is incredibly bright. 200 mW of green should be very visible even in direct sunlight at the ranges you're likely to be using your shotgun. I'd advise against blue...

Is this a new occurrence or has it been like this since you received it? The first thing to check is whether the lens is dirty. Any visible smudges or debris? I would check both surfaces of the lens. Next I would inspect the laser diode window. If that's dirty, it would affect the beam much...

You need to give us more than a crappy photo of a blue blob in the void if you want help. Maybe try telling us about what kind of laser it is, what lens is in it, etc.

Of course the fancy tools would make life easier... I could do a job that takes me 4 hours by hand in 1 with a mill. But thats 2k that I don't have laying around right now so it's the old-fashioned way for the time being. Hacksaws are definitely more... well, "hacksaw" than "scalpel." But they...

Nice work. Classic DIY. If charging the batteries is a PITA, consider installing a USB Li-Ion charger to the build. I put one in my latest project and I like it. You're right that fancy machines aren't needed for basic fabrication. I've got a drill press and recently added a belt sander to the...

Made some good progress this week. There is still a lot of work to do but it's functional and fits well. I designed a very simple mechanism to align the beam and it turned out great. The hex screw that secures the module in place is threaded into a blind hole. The aluminum heatsink has enough...

Cool idea. You could probably get more retraction if the battery compartment were larger, instead of the laser head. Or you could have a middle section that collapses into the battery compartment (so it would be thinner in the middle). Practical? Maybe not. But it would be interesting if it...

I guess everything is a controversy these days... Since everyone is so upset, ill share my top secret dangerous ideas: Recipe for highest power/gram handheld laser: 10W 808nm c-mount diode Minimal aluminum heatsink Basic current regulator High discharge lipo Skeleton host Its more fun when we...

Haha... No offense taken. Always good to hear an honest opinion. Most people that do custom work on here dont seem to use mills, and instead use a lathe for every operation. This is why everything anyone makes here either looks like a dildo or a lightsaber... Which is why I went to Trinh. I...

Haha so sad. Maybe the new one will be more interesting to you once it's finished though it won't be a simple rectangle. Or maybe you won't like it still. Is it the brass color that you don't like? I'm not sure what "discount cigarette store" means - maybe because I don't smoke cigarettes.

Hi. I have such a thing. I installed a 589 nm CNI module into a custom host made by a member here. See here for details: https://laserpointerforums.com/threads/589-nm-cu-ni-ti-host.106392/ I am also currently working on a hand-made host for a 561 nm module. See here for details...

Updates on the build: As of 2 weeks ago, the main parts of the housing are roughed out and honed to a flat, brushed finish for testing the fitment. Holes in the base plate are threaded by hand. I also replaced the wiring with some high-quality silicone insulated silver wire I thought I had...

I'm going to ignore the drama because that's boring. In response to the original post: I think this sounds like a fun challenge. I can think of a few ways it might be possible to beat that record but I think I'll keep those ideas to myself for now. Why not do a little research and come up with...

Nice laser! I've been working on some parts for a 561 nm module and find that the camera cannot properly record that wavelength. Others have noted that in the 570 nm range, the beams also come out green. After trying multiple cameras, I think it's just a weakness of CMOS sensor technology. I...

Very cool. That's a chunky pointer for such a simple-looking laser. This must be one of the oldest operational diode lasers among the collections on this forum. Some have some very old gas lasers as well.

FLIR will detect small differences in "heat." So if you have a sufficiently powerful, invisible to the naked eye laser, when you project it onto a target that can sufficiently absorb the light, the projected beam will have a recognizable heat signature. You won't see the beam, of course, but is...

The rule of thumb is to use the manufacturer's current ratings. Based on my analysis of the data compiled from many different laser diodes and laser diode types, the laser diode manufacturers' spec sheets rate a diode for the current that produces maximum efficiency in terms of energy in and...
