Re: Source for thin glass?
I use old glass plates, I keep them for the odd cameras that won't accept 2mm. The problem is that here in Europe 2 mm is the thinnest glass that can be sold in a regular glass supplier, you have to go to specialists to get thinner.

Glass shops, windows...., should be able to order it for you. Otherwise, there is Focal Point in Florida.
Re: Source for thin glass?
Shucks. I overlooked this. Schott, 1.2mm thick. Search for more perhaps under optical windows.

$38.00 for 20 pieces, but surplus shed sometimes accepts offers.
Re: Source for thin glass?
Great idea - I'll keep an eye out for some plates. Jac, the SurplusShed glass is perfect - just need to figure out if I want to buy 20 12x12" sheets, I'm sure I'd never need to buy any more after that!
Re: Source for thin glass?
Nathan, not sure if it would fit but the Chinese TLR fresnel screens on ebay are good, a big increase in brightness and ease of focusing. I bought one about 5 years ago meaning to use it in my Yashicamat 124 but in the end used it in my Microcorrd (essentially a British Rolleicord).

Re: Source for thin glass?
I also bought a screen (actually a pair I think) from ebay a few years ago. They were sold as 6x7 for a mamiya, but one of them now lives in a Flexaret giving a huge increase in brightness - largely due to the built-in fresnel lens. Re-purposing a cheap commercial screen gives a better performance than plain glass. In the Flexaret, the focussing surface was the one next to the fixed surface of the mounting frame, so no re-shimming or adjustment was required.
Re: Source for thin glass?
Look for suppliers of scientific float glass. That was where we found cover glasses for the Super Screens.
Re: Source for thin glass?
Howard Glass in Philly has a variety of glass, and thickness. I have bought glass from them for my enlarger and Condit system. They also have Schott glass.

Re: Source for thin glass?
You might try taking the glass from a flatbed scanner. I salvaged the glass from a throwaway, a few years back, but I did no measure for thickness.
