A mirror box integrating chamber is often used for this application. Four mirrors are mounted together at the edges to form a box or tube. The light is directed into this chamber, it reverberates about. In the process it arrives at the negative / slide totally diffused.

I was looking of a upgrade for my Source4 fixture to LED. The OEM unit are backorders and twice as much as this unit. The first two I purchased shipped from the US quickly. After using them on a project I ordered 2 more that drop shipped from China and took about 30 days to get.

I would intermix LEDs of the different wavelengths, but should I put sources on the side walls of a white light box which has diffusing walls and back surface? should the box be square or circular? circular may benefit from the 1/r rule and result in a more homogeneous light on the back wall/diffuser. Or should I put them not on the sides but on the back side, behind one or two diffusers? or maybe on the walls but directed to the back?

As a special static lighting and different power and sizes. Ellipsoidal light can be used as various scenarios include but not limited to theatre, tv studio, museum.

The best design for dust suppression is a lamphouse that delivers a uniform light that is highly diffused. This will be an integrating chamber. This can be a box, or a sphere painted flat white. Light is allowed to enter the integrating chamber via holes in its walls. The light reverberates about and arrives at the negative / slide with no apparent direction.

Based on the answers to my question Can I use a LCD as backlight for acquiring film using a DSLR? and the link provided about optimal light sources for negative film I would like to build a light source which emits no orange at all, so that the orange of the film won't be recorded by the camera.

Such integrating chambers cannot eliminate dust spots, but they totally diffused light acts to suppress the visibility of dust on photo materials. Let me add that the end of the mirror tunnel, next to the negative / slide is covered with milk glass or milk plastic (white translucent diffuser).

I have no experience on the topic and the goal is to obtain a uniform light field. It will be diffused light, not collimated. Collimated may be much more difficult so I can skip it for now.

Uniformlight meaning

Likely the best lamphouse design would be collimated light. Meaning the light rays from the light source arrive at the negative / slide as parallel rays that uniformly illuminate. The design of such a lamphouse mimics the condenser enlarger. These utilize two plano convex “condenser lenses”.

Ovation's products have brought a new level of professionalism to our events. The clarity, brightness, and versatility of the lights have greatly impressed our audience.

Such a lamphouse has the undesirable trait of showing every speck of settled dust. Best is a lamphouse that suppresses dust spots.
