Dear Frans,

Regarding the circular structure in the MTF Mapper chart, will the analysis still be successful even without this structure?
To evaluate lens performance at 1x magnification using an MTF Mapper chart, I'm planning to print the chart using a metal stencil (the kind used for soldering).
Due to the limitations of the metal stencil, I can't reproduce the hollow circular structure. Will this cause any problems with the analysis?
I would appreciate your opinion.

Regards,
