Optical system with compensated spatial dispersion
The optical system has a first optical element ( 11, 17, 19, 26 ) and a second optical element ( 12, 18, 20, 27 ) arranged along an optic axis ( 10 ). The optical elements are preferably made from crystalline material with a cubic crystal structure. The first and second optical elements have first a...

| Zusammenfassung: | The optical system has a first optical element (
11, 17, 19, 26
) and a second optical element (
12, 18, 20, 27
) arranged along an optic axis (
10
). The optical elements are preferably made from crystalline material with a cubic crystal structure. The first and second optical elements have first and second orientations in relation to the optic axis, which are preferably rotated with respect to each other according to the rotational symmetry of the material. At least one of the first optical element and second optical element is pre-stressed by applying a compressive stress ( , 1, 2) thereto. The compressive stress is applied radially symmetrically relative to the optic axis (
10
) and compensates for spatial dispersion. |
