Thx
I forgot to tell that the system we intend to test is at f/6 ('cause i was
looking for a stock item and not prepare myself) , therefore detail size
should be approx 6u and not 0.5 u
Therefore, for a 20 mm plate i believe that the anfular accuracy should be
approx 5 arcsec.
I'll probably recommend my customer to computer generate a mask of random
b/w ponts, at 180 deg symmetry, take it at 0.1x mag on a photografic plate
and then bleach it
If and when we do it - i'll let u know
best
