depending upon the refractive index of the glass you are going to lose 6% off each surface, not a trivial amount!

Pat, I am aware of that..
but it is only one surface affected.. so 6% is not a big deal. I can absorb that.
This is equivalent to reduction in aperture from 140mm down to 135.7.. negligible.
I am pretty sure the loss due to current scattering on the damaged surface is worse.. not to mention the loss of contrast.
