Abstract

Lateral chromatic aberration or lateral color refers to the change in image position with wavelength, and so to the change in magnification, at the image plane of an optical system. In an imaging spectrometer, this introduces a slop and/or curvature in the spectral image line of an object point, a feature that is known as keystone. The variation in keystone when the spectrometer is illuminated with and without the optical system under test allows measuring the lateral chromatic aberration in a wide spectral band.
