Richmond Solarbeam Integrator Question

[jsheridan]

Does the light integrator itself have any other adjustments on it other than just that little small window with the dark glass behind it. sometimes there might be a small set screw or something you can turn that will focus the lense.

There's another hole on the front of the integrator, but nothing inside that looks like it can be adjusted.
