Abstract

A surface element of a holographic optical element (HOE) deflects two given rays into two given output rays. This advantage in comparison with a refracting surface element permits a simple solution for the attainment of aplanatism. The aplanatism ensures a good image quality in an image plane the coordinate axes of which are two spatial coordinates. If a HOE is used for spectroscopic purposes then the image plane is described by a spatial and a wavelength coordinate. For this case the usual aplanatism is generalized to colour aplanatism. A condition and examples are discussed.
