Achromatic Schmidt corrector plates.
Abstract
Two types of achromatic Schmidt corrector plate are described; both give an on-axis Strehl number S ⪆ 0.8 over an extended wavelength region. It is found that this specification can only be achieved by combining a positive and a negative plate and by restricting the speed ratio D/N3 of the system. The theory is illustrated by numerical examples.
