Hi all,

 

During tolerancing of some lenses (using the mtf as criteria) I get the “Lens cannot be traced, tolerances may be too loose!”

However, opening one of this the monte carlo files it seems like the mtf is bad but larger than zero.

 

What can be the reason for this?

 

Thanks,

Nadav

Edit:

geom mtf makes problem while diff mtf doesn’t.
