Andy,
I do not have any optics experience but the lab I work in is equipped with a Nd:YAG laser so my PI and other co-workers do have some experience in optics. The lamp we are using has an ellipsoidal reflector and at the focal point we measure ~18 W of broadband power. Of course to get...
Also, how do you burn through the irises? From the heat? You don't have water-cooled irises, or at least have the light from the lamp pass through a condenser first to absorb most of the IR?

Where can I find a water cooled iris? A Google search doesn't provide much help. Thanks.

We have adjusted the back reflector to obtain a good image. And we have a good image. The problem is now collimating the light without losing a good bit of power. If we use several irises with 1-2 mm apertures we can collimate nicely but we go from >10 W to less than 0.5 W. And that is total...
Hi,
I am trying to collimate light from a mercury arc lamp. I know this question has been asked before here https://www.physicsforums.com/showthread.php?t=413437&highlight=collimation but it was first posted last year and since my situation is a bit different it didn't quite answer all of my...
