16x + DX30 - combining the cheap and hard way!

[Switch]

Well here's my shot at combining green and red.I consider it a semi success considering the "precision equipment" I used. It took a lot of time and was very frustrating.Everything was wobbly, the DX30 batteries started to drain, i had to watch duty cycles, the room was hot and smeled really bad from all the smoke.Well anyway, here are some pics of the yellow beam and my "setup".











My dichro is the brewster window salvadged from a DVD burner. And yea, I realise there's a LOT of mess in my room

nice

Didja use ciggy smoke to visualise the beams? ;D

Lol.I actually don't smoke.Those cigarette packs aren't mine. I actually used toilet paper and plastic in an ashtray for smoke And the dichro mount is a "modded" q-tip ;D

That's probably worse than flat-out smoking

But cheaper. And I don't think it's worse since I only do it once in a very long while.

I found if you spray deoderant, from a deoderant can that as a fine particlizer thingy, you can see the beam pretty well, i could see the beam from a <1mW laser with no trouble at all, and It stays in the air for a while too, plus it also smells nice ;D

But anyhoo back on topic, nice work, now you need to build it into a handheld pointer ;D Or is that a job for wannaburn ?

Not enough green to make a good yellow.

It wouldn't really work as a pointer because of the huge difference in beam diameter.I just focused the red so it converges to match the green better, but a few feet away the red was huge. I would need to open the DX laser up and play with the last 2 lenses.

Not enough green to make a good yellow.

I know, there's too much red.The batteries in the DX30 were a little above 1.1V so it was dimming out by the time I got to the camera.

almost looks like a neon color, very dark orange

I guess the green/red ratio is off, but that is of little concern as its easily adjusted...

But what was wondering about: does that 'dichro' actually do a good job in terms of reflecting red and passing green, or is it only so-so? From the picture it seems like an awful lot of red is passing, and hitting something (paper?) on the right of the picture.

Yea , it's hitting a dx envelope.But at the right angle of 45 degrees it reflects more than 90% red.I set it at that angle to lose some red and also to minimize green reflection.

I'll have to try it again with good batteries ,but I also have to get a better setup, I'm not going through that all over again. :

Here's another green + red pic Not really beam combining but didn't know where else to post it
