Abstract
An optical component is arranged in the beam path of a scanning microscope. The optical component has a plane entrance surface through which a light beam bundle can be incoupled at an entrance angle, and a plane exit surface through which the light beam bundle can be outcoupled at an exit angle, which is different from the entrance angle. The optical component contains at least two elements that exhibit at least two different refractive indices.
Claims18
A scanning microscope that defines a beam path, comprising an optical component, arranged in the beam path, that comprises a plane entrance surface through which a light beam bundle can be incoupled at an entrance angle, and a plane exit surface through which the light beam bundle can be outcoupled at an exit angle, whereby the optical component contains at least two elements that exhibit at least two different refractive indices;
- and the entrance angle and exit angle are different;
- wherein the light beam bundle contains light of at least two wavelengths and wherein the exit angle is identical for the light of at least two wavelengths.
An optical component comprising at least two elements that exhibit at least two different refractive indices and that define a plane entrance surface through which a light beam bundle can be incoupled at an entrance angle, and a plane exit surface through which the light beam bundle can be outcoupled at an exit angle, whereby the entrance angle and the exit angle are different and whereby partial beam bundles divided from the light beam bundle by the optical component are sufficiently spatially separated from the light beam bundle that they do not interfere with the light beam bundle;
- wherein the light beam bundle contains light of at least two wavelengths and wherein the exit angle is identical for the light of at least two wavelengths.
