Alignment question.

[buffo]

To allow the dichros to be moved on the baseplate, all you need to do is enlarge the hole that the mounting screw passes through. I suggest carving a narrow slot, in fact, so that you can move the dichro back and fourth. (This is the way my dichros are mounted.) Use a large, flat washer on top so the screw will hold the mount firmly in place on the baseplate.

You've got plenty of elevation adjustment on your lasers, judging by the picture you posted, so you shouldn't have any trouble there.

From the picture, it appears you'll want to raise the green laser some, and drop the blue laser a bit. As for the problem of getting the red and green beams to overlap perfectly while still getting them on the scanner block, that's where having some lateral motion on the dichro mount (from the slot I mentioned above) will help you out a lot.

i am sure youre already aware of this-

but, in my opinion, DO NOT even worry about your far field alignment or your alignment onto the scanners yet.

adjust your lasers FIRST so that each laser is PERFECTLY aligned onto your dichro faces. (Near Field alignment). once you have your lasers perfectly overlapped in near field. adjusting them for far field and onto your scanners is a piece of cake. this is where you adjust your dichros.

the height adusts of your lasers and the physical placement of your dichros should be your MAIN concern! get your near field first. then your far field.

(a wise man named obi-wan-buffo trained me this way!)
