Collimators and GM20’s

[Kirk]

Collimators and GM20’s still available. GM20’s have mounts and arms with mirrors. Collimators are 4:1 with gimbal mounted bounce mirror. See previous post for more info. $50 for collimators, $75 for GM20s or best offer.

Hello, this is my first reply as a new member. Well, I'm interested with some questions.

Would the collimators work perfectly with 450nm (3mrad and 4.4mm) and 635nm (2.5mrad and 4mm)? Could you possibly please advise the resulted beam mrad and diameter?

Looking forward... Thanks so much.....

The collimators have a fine-thread focus adjustment so you can adjust them as needed. They use plano singlet lenses so theoretically there will be a slight difference in focus for different wave lengths, but this is not visible in beams. The lenses are +100 and –25 which gives a collimating factor of 4, so the diameter will be 4 times greater and the divergence 1/4 of the input beam. Hope this helps.

There are 16 sets left. Anyone want to make an offer on all of them? $1500 OBO for all.

I'll give ya $100 shipped for one of each; collminator set up and GM20 set up. If that's cool, shoot me a PM.

I got my set yesterday; nicely packed and quick shipping. I really like the collminator set up; it has a big ass mirror on an older style MM1. Very good for the price.

Hey Aaron, Glad you liked them!
Looks like theirs 16 GM20's and 20 collimators left, if anyone else is interested.

[Kirk]

Still some left. How about 12 GM20s with collimators for $1000?
