Light Leakage

Hi everyone,

I did some more "testing" last night on my OHP/LCD system. It is working well. Still not perfect, but I am very happy with it. In an attempt to maximize my results, I was thinking about the light leakage from various areas of the system. These are the primary spots where the light is leaking:
1. fan opening
2. above the stage after the light leaves the LCD panel

Does anyone know if there would be significant improvement if one was to contain these leaks?

Has anyone ever tried to build a shroud or cover to contain this light leakage? I have been thinking about it and realize it may trap in some additional heat if not vented properly.

Does anyone have any pictures of their solutions?

Thanks, Happy New years to everyone....
