Re: scanner glass replacement

[Arthur Entlich <artistic-1@xxxxxxx>]

Great, give us more knowledge, then...  (I'm always hungry)...

I do understand the desire for optically flat glass
for this application.  And although window glass that I've seen tends 
toward slow ripples and distortion, most of the framer's glass I have 
worked with has been fairly optically "pure" (although not always).

However, that being said, perhaps you can answer these question, which 
will be more valuable to anyone needing to replace their scanner glass, 
since you have a greater knowledge base about such matters:

Where are there good sources for such glass?  Do most glass suppliers 
carry it, or is it only available from certain facilities?  Is it made 
to order for scanner companies, or is it a generic glass they simply 
order? About how much is it a square foot, or is it only sold in set 
sizes?  Does it vary in thickness?  Is there a standard thickness used 
for most letter and legal sized scanners?

Inquiring minds want to know.
