15 April 1993 Color and spatial aplanatism for corrected holographic gratings

Image plane in devices with dispersion contains a spatial coordinate and a wavelength coordinate. For the wavelength coordinate we define chromatic aplanatism in analogy with usual aplanatism. The feasibility of this definition is tested by ray tracing. A condition for color aplanatism is derived which can be used for the construction of color aplanatic surfaces. In the neighborhood of a color aplanatic point we find a very high spectral resolution in combination with a high aperture. In some cases of color aplanatism spatial aplanatism occurs along the spatial coordinate of imaging. This additional aplanatism can be a starting point for a combination of spatial with spectral resolution. This new task is interesting for remote sensing from satellites. We give variants of gratings with spectral aplanatism and with spatial resolution.
