    Source for optically flat glass.

    Does anyone have a source for optically flat glass in 5X7" to 10X14" sheets about 1mm-1.5mm thick? I checked at Edmund and found nothing.

    Sandy about the only place I could think of would be Optio Sigma, last time I checked they were carrying some, but that has been a couple of years ago,

    www.optiosigma.com

    Last I checked, they didn't have much on their website, and you had to order a catalog.

    If you fail to find any there, you might check with Stonemills in Canada. They have had optically flat glass for the Durst neg carriers.

    What specifications are you looking for, in other words how flat is flat?

    Dave,

    I would settle for any good quality float glass. The main requirment for in my application is thickness, which needs to be 1mm-1.5mm.

    Okay,

    I will do some checking, the glass I have made for my screens is very flat, but we are at about 2mm on thickness...

    I will call the guy who pours my glass for me and see what he says about going thinner.

    S. I. HOWARD GLASS Co. has a very wide selection: http://www.howardglass.com/.

    I have no experience with them.

    Sandy,

    try Precision Glass and Optics (PG&O). I can get a contact name when I am at work tomorrow if you need it.

    We use them for glass substrates all the time. Typically, we use 1" glass (0.7mm thick), but I have obtained 5" and 6" (1mm thick) rounds from them.

    Perhaps Melles Griot. They have many cool things for optics and photonics research applications. You might contact http://www.photonicsspectra.com/ magazine. My father used to have a subscription and I remember it as being full of ads for optical research paraphenalia. Check the ad index, this, for example might be promising. Good luck.
    Celac.
