Josh, maybe you can send a picture of that lense to Gordon. The lense picture you sent me looks like the standard Hilux. The ones I had were the gigantic ones. I think I already gave them away, but if not and I find them, I'll give them to you to play with. The pink one Gordon talks about is the style I scanned a picture of and sent to you. Grumpy

I remember, some people saying, those are NOLUX devices. The art of how all the light stays within the lens, and nothing comes out of them. I liked the art of making theese large quality prisms, and to a certain extent the "Nolux" with large and thick glass structures is true, but theoriticly prismatic squeeze is superior to cylindrical lens types, at least when theese were manufactured. I still have the pink types somewhere, and I liked them. The lens in front must be a convex lens with the desired projection distance as focal length, as the prismatic trick works only in indefinite distasnce. They do look like ordinary protective glasses but are lenses, actually. The focal length is engraved in the front glass. Most of them were specific to the theatres of the 1950's, so a minimum of 60 - 80 ft generally applies. To get closer, you could actually use 2 lenses infront of the prisms.
