Dear Paul,

I have a chart which specifies relative expansion over temperature for 0 to
600 degrees Celsius. Please contact me directly and I can send it by e-mail.

Best regards,

P.S.: Plan Optik produces glass wafers (from Pyrex or other materials) for
MEMS and semiconductor applications.

Does anyone have the Coefficient of Linear Thermal Expansion for Corning
Pyrex 7740 at 500 degrees C?

Current data is 3.25 through 300 degrees C.

Thanks for your help,

Paul
