Achal,
How big is the size of the openings within the grids? As I remember from
years ago the size may be variable depending on the slot types of EM grids.
I imagine that you're using apertures of less than 500 nm. Or do I
misunderstand you and you use the whole circular grid as the pinhole lens?
Thanks
