Paper Abstract

Achromatic doublet theory is recast for the 1-2.5μm short-wavelength infrared band, suggesting the desirability of combining barium fluoride with specific high index optical glasses having large differences in primary SWIR dispersion and small differences in partial SWIR dispersion. Candidate combinations of materials are screened empirically using the performance of optimized f/3 airspaced achromatic doublets employing barium fluoride as the positive element. Polychromatic RMS geometric image spot sizes appear to increase quadratically with difference in partial SWIR dispersion between barium fluoride and the complementary glasses. Examples of complex (fast, wide field) systems demonstrate the utility of the most promising combinations.
