    Hey guys,

    I was given a few plates of optically corrected glass. This is the glass used as a coverplate on fotocopy machines - the piece you put the paper over and it scans the image through.

    Does anyone know anything about this stuff? Will it cut out a lot less light than normal glass? I'm planning a DIY light hood and want to use this as the "baseplate" below the unit to protect from splash/creep.

    Thanks much.

    Mmmmm..... no.....

    AFAIK it is just glass that is made to very high stds, its thickness would be extremely critical, in other words the surfaces are parallel, this would prevent any distortion.

    I think the glass might be hardened?

    Thanks guys,

    Yeah from what i've read they glass is pretty pricey. Mostly because of extremely stringent controls on heating and cooling process (very slow). The idea is to get as little distortion as possible, and best transmission of colours, i was particularly wondering if this extends to all the spectrum we use in our lighting, and if this is good stuff for a baseplate beneath my lights....

    Well, I'm actually using it right now and have been since I've moved my "larger" 70L nano. :razz: So cant be that bad. Just wondering if its "ideal".

    I'm sure its better than any other. I think it probably is toughened as light glass needs to be (otherwise it breaks from the heat.)
