Abstract: The invention relates to an autofocusable microscope objective having an optical system of a plurality of optical components each formed by a lens or lens group. Here, one of the plurality of optical components is a liquid lens to effect autofocusing of the microscope objective, and the optical system is formed as a stationary system.

Abstract: A Miniature zoom lens, in particular for use in mobile telephones, in which the zoom lens, as viewed from the object plane, has the following in the stated sequence: at least one negative first optical lens group, at least one negative second optical lens group, at least one positive third optical lens group, and at least one positive fourth optical lens group. The second, third, and fourth optical lens groups are configured in such a way that focusing is achieved solely by displacement of the fourth optical lens group, and during the focusing the positions of the second and third lens groups remain unchanged.

Abstract: A description is given of a macro objective (M) with a corrective compensation of aberrations (Continuous Aberration Suppression; CAS). The macro objective has a first positive optical subassembly (A), a second nearly afocal optical subassembly (B), a stop (APE), a third nearly afocal optical subassembly (B?) and a fourth positive optical subassembly (A?). The third optical subassembly (B?) and the fourth positive optical subassembly (A?) are designed with mirror symmetry relative to the optical subassemblies (A, B) upstream of the stop (APE). The nearly afocal optical subassemblies (B, B?) are displaced jointly inside the macro objective (M) along the optical axis (OA) with the aid of mechanical means in conjunction with linear magnifications of ????1. As a result, the macro objective (M) achieves outstanding imaging properties both over a wide range of linear magnifications (??=?2.0 to ?0.5) and over a wide wavelength spectrum.
