WAVE ABERRATION OF THE POINT SOURCE IMAGE AT THE CENTRAL SHIELDING OF ENTRANCE PUPIL
Annotation
Conditions are defined under which wave aberration for both extreme rays at an entrance pupil of optical system and rays at the beam shielded part border equal zero. The conditions fulfillment is shown to reduce considerably residual wave aberration of the point source image.
