I'm looking for two things. First an inexpensive, high powered green laser. I bought mine a few years ago, and I expect that you can get a lot more power for $50 worth of laser now than you could back then. Has anyone done any shopping for them lately?
Secondly, I'll want a way to mount one axially behind a k-mount lens. M42 would be sort of easy, just drill two holes on the same axis, one the size of the laser, one 42mm, and then thread the hole for m42 lenses. I sort of did this with my current setup which uses an old 50mm Argus C3 lens. This spreads the beam nicely, but I'd like to be able to change focal lengths to change the spread of the beam, and I have a much wider range of K-mount than m42 lenses. If there is some sort of a screw mount that I can get adapters for k-mount to screw mount, that may work. I could also probably get minolta to this screw mount, or nikon to this screw mount adapters too. I could, in theory, also have a friend with a machine shop fab me up something that is the right dimensions to mount a K-mount lens. Or, possibly, drill a hole, mount a quality back cap in it, and use that to mount a k-mount lens. Anyways, I thought I'd throw the idea out to see if anyone happens to know of something that would do this well, for not much money. A couple of my previous laser calligraphy experiments. Note that my calligraphy skills are quite lacking.
