Abstract:
An arrangement for generating a defined longitudinal chromatic aberration in a beam path of a confocal microscope, said arrangement comprising:a confocal microscope including a lens which generates an intermediate image and a microscope objective which images an object to infinity; andsupplementary optics arranged in an imaging beam path between said lens and said microscope objective, said supplementary optics having a longitudinal chromatic aberration and a plurality of dual lens optical elements,each of said dual lens optical elements having a converging lens and a diverging lens of different materials, said converging lens of a first of said dual lens optical elements having a glass type that corresponds to a glass type of said diverging lens of a second of said dual lens optical elements, and said converging lens of said second of said dual lens optical elements having a glass type that corresponds to a glass type of said diverging lens of said first of said dual lens optical elements, the first and second dual lens optical elements having the same focal length with different mathematical signs with a deviation of +/-5%.
