Optical diffraction arrangement for use in e.g. optical spectral apparatus, has mirror whose reflection plane is aligned parallel to and in symmetry plane of optical diffraction structure, where rays

The arrangement has a mirror (2) whose reflection plane is aligned parallel to and in a symmetry plane of an optical diffraction structure (1). Rays (4.1) that are incident in a defined area outside of an aperture are reflected on the diffraction structure, where the size of the diffraction structure is increased upto a factor two. Outside radius of the defined area outside of the aperture of the diffraction structure corresponds to the double radius of the aperture of the diffraction structure.
