[RASMB] window glass suppliers

[Virgil Schirf]

Dear Mircea,

Try Meller Optics at melleroptics.com for more reasonable prices for 
quartz and sapphire windows. With regards to breaking quartz windows 
with the use of titanium centerpieces, you might want to try to torquing 
the cell to 110 - 115 inch-pounds rather than 120 inch-pounds and make 
sure the gaskets are new. I'm assuming you are doing high speed runs so 
you might also want to try using regular epon-charcoal, 2-sector 
centerpieces making sure that the menisci are closely matched and the 
sectors are almost full so that there is no pressure difference between 
sectors. Tom Laue's group at CAMIS also manufacture an epon centerpiece 
rated to 60,000 rpm as well.

Sincerely,

Virgil
