collimating my laser collimator
Hi Guys,
I have been trying to collimate my laser collimator as it was out by quite a bit when I bought it. It is a cheap(ish) Bintel collimator (by GSO).
I made a cradle, adjusted the screws until the beam was as central as I could get it - but here is the problem: It doesn't project a "dot", rather a line on the wall.
There is quite a bit of red glow around the brightest part of the line as well, and this glow is not symmetrical.
Is this caused by the beam hitting the edges of the collimator on its way out? Is there a way to fix this?
There is also a larger allen key screw towards the front of the collimator, directly opposite the angled plate - does this have something to do with it??
Any help is greatly appreciated,
Cheers,
Steve.
