Abstract
An athermal chart, which plots chromatic dispersive power and thermal dispersive power on a Cartesian coordinate, is one of the graphical design methods for achromatized and athermalized optical systems. We expand the ideas of an athermal chart into a multilens system that is composed of thick lenses spaced apart by weighting the ratio of the paraxial ray heights at the lenses or the surfaces to the lens power, the chromatic dispersive power, and the thermal dispersive power of each lens or surface. We describe the methods for treating air space and lens thickness on the athermal chart with two-component optical systems. It is clarified that the proposed method is effective for athermalized optical system design through the evaluation of an IR optical system in the 8- to 11-?m wavelength band.
