In summary, the conversation discusses the placement of a sanded PMMA sheet in a closed box with fluorescent tubes in order to achieve maximum light scatter. It is debated whether placing the sheet closer to the light source or closer to the receiving plane would be more optimal for achieving this goal. The ultimate goal is to reduce the distance between the light source and receiving plane while still achieving sufficient scatter.

Hi,

I have 4 fluorescent tubes in plane A as a light source. Plane B is receives the light and is parallel to plane A. In between I'll put a sanded piece of PMMA in order to scatter the light. Each plane is approximately 250*300 mm. For a fixed distance between A and B, let's say 200 mm, what would be the optimum position of the sanded PMMA in order to achieve maximum light scatter at B? This is all in a closed box of 250*300*200 mm.

If you put the diffusive sheet very close to the light you can clearly make out the separate tubes which might mean that maximum scatter is not achieved. On the other hand if you place the diffusive sheet against plane B there will hardly be any scatter at all.

Would you say that placing the sheet as close as possible to A is optimal or is the optimum somewhat away from A?

The goal would be to reduce the distance between A and B as much as possible to get a small box while still achieving sufficient scatter.

Thanks in advance for any thoughts you have on this.

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?
 

1. What is the purpose of optimal spacing of a diffusive sheet between light and destination?

The purpose of optimal spacing is to maximize the efficiency of light diffusion and ensure that the light reaches its intended destination with minimal loss or distortion.

2. How is the optimal spacing determined?

The optimal spacing is determined through mathematical calculations and simulations, taking into account factors such as the intensity of the light source, the refractive index of the material, and the distance to the destination.

3. What are the benefits of using optimal spacing?

Using optimal spacing can result in increased light transmission and reduced light loss, leading to improved performance and cost savings in applications such as solar panels, optical fibers, and LED lighting.

4. Is there a universal optimal spacing for all materials and light sources?

No, the optimal spacing can vary depending on the specific materials and light sources being used. Factors such as the material's thickness, surface roughness, and absorption coefficient can also affect the optimal spacing.

5. What are some potential challenges in achieving optimal spacing?

Some challenges in achieving optimal spacing include manufacturing limitations, variations in material properties, and the need for precise and accurate measurements. It may also be difficult to determine the optimal spacing for new or novel materials.
