+1 Burninglaserguy, for helping a noob instead of berating them for not asking a question the way you wanted to read it. luckycharms, if someone rubs you the wrong way, the proper way to handle it on the internet is to ignore them. The specifications on that laser seem fine. Main concern is...

Quick and dirty of it is that laser diodes are just more sensitive, due to the fact that not only do they have an active material turning electrons into light, but unlike LEDs, they are also a precision optical device that has optical faces aligned a certain way. These mirrors aren't anything...

Those dotted things are part of the plant, or is it a bug? https://gobotany.newenglandwild.org/full/ < this was a neat resource, but I think it only applies to major species in new england. Still, neat what it can find by asking the right questions.

lower wavelength photon have higher energy, thus Vf of device is higher.

https://www.google.com/search?tbm=isch&q=*.gif+site%3Alaserpointerforums.com&tbs=itp:animated might help :whistle: It is STILL a lot of work weeding out what is a member av and what is just some random gif posted in some thread somewhere, though!

I know I applied for the job and they just laughed at me :mad: Joke's on them. I just shipped them a zombie cat in a box. It was dead, but I closed the box and it came back to life. I assume.

regulation basically means it keeps spikes, noise, and overall current below a certain threshold. If the supply can't supply more than what it requires, the battery just gives it all it's got. So, it goes from taking an input that is too much, bucking what isn't needed, and giving what's...

I have a pal who maintains the quantum mail sort machine at USPS. Turns out, one of the new techs peeked inside the machine, and that instant of observation ruined the entire mailflow, so now they are back to sorting by automatic machine instead of quantum parcel entanglement :can:

I like the focus adapter idea! Added benefit of making it harder for debris to get to the lens threads. An o-ring groove might even make it water resistant, and a glass slide in front of the lens would make it close to impossible for dust to contaminate your lens. Very cool host, and I like...

Hey Teej! Welcome to the monochromatic, coherent side of lights :-) There is something for everyone here, and even a flashlight section! Whether you want the best of the best, learn to DIY, or even just want to keep up with the exciting times in the laser hobby world, this is a great place to...

Your post did not contain the usual 3 pictures. Are you the real madmacro? I didn't realize uranium glass was so emissive! I know that there's a lot in that beaker, but still!

If that is a fancy, high quality, single aspheric glass, superduper G5000xt lens, chances are that the lens element is supposed to go closest to the diode. Have you tried turning the lens around and screwing it in that way? It shouldn't hurt, since the lens barrel is hollow and the LD is flush...

It appears to be meant to flush-mount into a flat panel, with only that knurled portion on one end, the rest on the other side of the panel. Is it some sort of electronic socket for mounting onto a control panel?

Pshhh, all you would need to do is google-translate it, and then translate the google translate :p Carry a mandarin-english dictionary for backup. Grapefruit-English or orange-English won't work.

I've seen folks light a match and put it in a clear glass bottle and put tape over the mouth of the bottle for a quick smoke chamber. But then you have to take a picture through a bottle.

I'm not allowed to not pick Detroit in some fashion :-/ I watched a few minutes of det vs. stl., thought that the blues looked like a HS hockey team in comparison to the wings. Also think that the blues didn't care much about that game anyways, though.

detroit and stl, stl to win in 7 after det lead series 3-0 Or pens and ducks, pens will win it because ducks are warm weather fowl.

cameras do funny things to pulsing light.

I salute you for impressively economical utilization of shelf space! You would probably be great at tetris! I was going to guess a light socket from an HID headlamp, but the tab and spring threw me for a loop.

Another way to think, is like a laser. If you see a "waist" in your beam, that's like the focal spot. To bring it closer, unscrew outwards the lens/optic/reflector. Yeah, people sometimes forget about HIDs midst all the LEDs. I've got a few old D2S from my headlights, reckon I might try to...
