Hi All , I have an ASC 20"x24" exposure unit which is basically 6 x UV flouro tubes and a sheet of glass in a box. The tubes are mounted approx 4"-6" from the glass and on larger screens I am getting a falloff of exposure towards the ends of the tubes. The question is - If I put a layer of some kind of diffusion material ( I am thinking of Lee filters 216 diffusion used in film lighting) will this even out the exposure? Obviously there will be an overall drop in light intensity and I will have to lengthen the exposure but has anyone tried this out?

Don't know about actually diffusing but I've seen a honeycomb patterned layer used to reflect the light in a more vertical, steeper angle at the outer edges. It doesn't increase the intensity though as much as reducing underutting.

You might want to use a smaller scoop coater, (or coat shorter,) and an extra strip of tape to make up the emulsion difference.

I wouldn't try to make a fluo unit's light more diffused...
