Hey everyone,
I'm looking for a little advice about adjusting the collimator attached to my Melles Griot DPSS.
Here's a picture of it:
(wow, that looks dirty..)
It has two tiny hex screws on it. I'm not sure how these are used and I feel I should get some more info before I go messing with them.
Here are two images for illustration. They are both from an event I did a while back. The first one is from about 50 feet away. (notice the difference between the beam and the beam on the other lasers coming from behind the camera and hitting the scrim.)
The second is the termination point at about 60 feet from the laser on the opposite wall. (you can see the oval shape of the beam here)
