I checked this against a version using B270.  Not much different...
The plano lenses (with slightly different radii) can still work.

However, with some consternation (Did you know that 1 N/mm^2 is
145 lb/in^2?;-), I was able to plug this design into Matt
Considine's vacpan calculator.  It comes up with an initial net
deflection of 0.01065" worked to a final sagitta of 0.00952",
using a force of 1.73 lb/in^2.

Are these reasonably doable numbers to work with?
