Planapochromatically-corrected microscope objective

摘要

The invention relates to a planapochromatically-corrected immersion microscope objective for high-resolution microscopy applications with changing dispersive immersion conditions, having a plurality of lenses and/or subsystems (T1, T2, T3) comprising lens groups and a corrective function (LA2) for eliminating spherical aberrations. According to the invention, the microscope objective has an additional corrective function (LA1) for eliminating longitudinal chromatic aberrations caused by dispersive changes in the immersion by changing the air gaps between the lenses or gap combinations, wherein the influence on the longitudinal chromatic aberration corresponds to a rotation of the curve s(λ), which describes the color point (s) as a function of the wavelength (λ).

1. A planapochromatically-corrected microscope objective for high-resolution microscopy applications with changing dispersive immersion conditions, comprising:
a plurality of lenses and/or subsystems comprising lens groups, having a first corrective function (LA2) that minimizes spherical aberration by changing air gaps or air gap combinations between the lenses, and a second independent corrective function (LA1) that minimizes longitudinal chromatic aberration by changing air gaps or air gap combinations, wherein influence on the longitudinal chromatic aberration corresponds to a rotation of the curve s(λ) which describes color point(s) as a function of wavelength (λ).
