[RASMB] Affordable Quartz window update!

[John Philo]

Chris,
 
Thanks for the info, but are you saying that this is a US supplier for the
same low-cost quartz windows mentioned by Olwyn Byron back in '99 from a
company called TSL group? And why not tell us all the actual 'reasonable'
price from Saint-Gobain Quartz?
 
Further, it may be important to note that the quartz windows supplied by
Beckman (made by Meller Optics) are listed by Meller as single-crystal
quartz, while these ones from Saint-Gobain are, I believe, probably fused
quartz. 
 
I've never been entirely clear exactly why Beckman specifies single-crystal
quartz, but I'm guessing there is a difference in strength or durability.
Can someone else on RASMB or perhaps one of the Beckman folks enlighten us
on this? 
 
I believe Neil Errington noted back in '99 that the low-cost quartz windows
from TSL gave higher noise and developed cracks with extended use above 50K
rpm.

Affordable Quartz window update

 

Dear RASMBers,

 

Just want to share this information with you that Saint-Gobain Quartz USA
sells windows that we can use with an affordable price.  I have done some
test (enclosed) on these products and feel it is comparable to the product I
got from Meller Optic.  I believe this company is the same company mentioned
in 1999 rasmb_archives. 

For those who are interested you can contact;

By the way, does any body know if we can purchase some reasonable priced
"cell Housing Plug"?

 

 

All the best.
