Two of my scopes just weren't as bright as I would like them to be. I replaced the thick diffusers with thinner material. The result was good diffusion and a much brighter experience. Do not do this with 6 volt 30 watt of 12volt 20 watt bulbs if you use plastic to do this as it will get too hot and cause a melt down. Otherwise it works very well.

Hi Greg Im interested in doing this to a polarizing unit I have, which material do you use?
Re: Greater Brightness
The front plastic diffuser on LED spotlight bulbs works well. Most are domed to some degree, but there are flat ones if you shop around.

There can be good diffusers made from drafting film, a trade name is "Denril." It's cheap and is cut just like paper.

I went to the hardware store and bought a translucent plastic cutting board sheet that was smooth on one side and rough on the other. I brought it home, allowed my 1.5 inch hole punch to visit and used it as the diffuser. It works fine. Cost about 5 dollars for two sheets .
