Re: I need a simple red module
Thanks, yeah I've done filtering with a red laser before in a cheap pointer i broke. On my webcam the dot appears as a whitish spot with slight pinkish red hues on the edges, and becomes redder the farther away it gets.
I think I will end up gettin a cheap 5mw red again
Are you using it for point recognition or something like that? A red would probably work fine, though webcams will still "see" green better than other colors because of their Bayer filter. Often, though, the laser dot can be bright enough that it won't even look like "color"--just an overly bright spot on the wall, so you might want to do some filtering before-hand. That does, however, depend on how far away it is, etc.
I'd grab a cheapo red (even 5mW) and then work up from there. You can get a dirt-cheap module for $4 from Hightechdealz, free shipping too. Greens can be power-hungry and need to be in a sufficient heatsink. They're also quite a bit larger than a simple low-power red.
