Hi,
I need to make large size outdoor projections in walls and buildings (30-50m) I was wondering if from the optical point of view, it would be very difficult to make a 35mm slide projector with a very powerful light beam? (HMI lamp/2500w/240.000 lumens)
-It is possible to block the 100% of UV/IR radiation and heat? (for a cooler light beam) With a cold & hot mirror and UV filter?
-It would be complicated to find the condensers system? (for a sharp, bright and with high contrast image)
Any advice is appreciated,
Thanks
