[Halld-pid-upgrade] DIRC Meeting: Friday June 3 @ 11 am

[Jochen Schwiening]

Dear all,

a quick check of the purchase order from 2011 suggests that we used 
Borofloat 33 borosilicate glass for that window.
The optical properties are better that the usual float glass (I think 
that the iron content was reduced, improving the transmission for 
shorter wavelengths) but not anywhere near fused silica. You can see 
some of the data at

or http://www.us.schott.com/borofloat/english/

Cheers,
	Joe
