Abstract

Bi-AGRIN cemented doublets, super corrected for zero axial color, spherical aberration and sphero-chromatism can show polychromatic performance in the range of 0.004 waves PV or better at the red and blue wavelengths for speeds up to F/2. These doublets are comprised of two elements of axial gradient index glass. The crown and flint elements are each designed with separate and distinct gradient glass lines, giving each element an axial gradient in refractive index and dispersion. This paper examines one design and its performance sensitivity to dispersion modeling via the Buchdahl and Sellmeier dispersion equations.
