Near-diffraction-limited F-3.1 apochromat singlet lens design enabled by spherical gradient index
A refractive singlet lens design that is near-diffraction-limited across the F, d, C wavelengths, hence across most of the visible spectrum, is presented. The lens is a reasonably fast F/3.1. An offset spherical gradient index (GRIN) and careful choice of GRIN materials enables this performance.
