    摘要： An optical system includes a first deformable lens having a membrane with a deformable portion. A sensor is configured to receive the light focused by the first deformable lens. An optical path extends through the first deformable lens and to the sensor. The first deformable lens is tuned according to an applied electrical signal in order to directly focus light traversing the optical path onto the sensor. A first volume of a first optical media and a second volume of a second optical media are defined at least in part by the deformable portion of the membrane. The first volume and the second volume are completely enclosed by the housing. The first volume and the second volume remain substantially constant for all configurations of the first deformable lens.

    摘要： A tunable, achromatizing optical system for use with a broadband imaging modality system for imaging objects having a range of longitudinal chromatic aberration (LCA) values. The optical system includes an achromatizing component and a parfocal component, for example, a zoom system. A method for tuning the wavefront curvature of different chromatic components of objects having a range of longitudinal chromatic aberration (LCA) values when imaged by a broadband imaging modality system includes the steps of providing a broadband imaging modality system having an entrance pupil, for imaging an object having longitudinal chromatic aberration; providing a tunable, achromatizing optical system; and varying the focal length of the parfocal component while maintaining a conjugate relationship between the achromatizing component and the entrance pupil of the broadband imaging modality system.

    摘要： An optically corrective microprobe for white light interferometry is disclosed. In white light interferometry which uses different spectral ranges, the dispersion-induced dependency of optical path differences on the wavelength between measurement light bundle and reference light bundle is compensated by an efficient, easily miniaturized arrangement. A reference beamsplitter with partially reflecting filters in at least two different spectral ranges for generating at least two transmitted measurement light bundles and associated reflected reference light bundles of nonoverlapping spectral ranges is arranged between the light output surface of the light-conducting fiber and the focusing optics. An axial distance between two partially reflecting filters is adjusted in such a way that a spectrally induced optical path difference to which the respective measurement light bundles are subjected when passing through dispersive elements in the light path to the object surface and back is present to the same magnitude between the respective reference light bundles.

    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).

    摘要： The imaging lens consists of, in order from an object side: a first lens group that has a positive refractive power; a stop; a second lens group that has a refractive power; a third lens group that has a negative refractive power; and a fourth lens group that has a positive refractive power. The first lens group has, successively in order from a position closest to the object side, a negative meniscus lens that is convex toward the object side, a lens that is convex toward the object side, and a lens that is concave toward the object side. The third lens group consists of a negative lens. During focusing from an object at infinity to an object at a shortest distance, only the third lens group moves to an image side along an optical axis. The imaging lens satisfies a predetermined conditional expression relating to a focal length of the first lens group and a radius of curvature of an image side surface of a lens closest to the image side in the first lens group.

    摘要： A lens unit (120) shows longitudinal chromatic aberration and focuses an imaged scene into a first image for the infrared range in a first focal plane and into a second image for the visible range in a second focal plane. An optical element (150) manipulates the modulation transfer function assigned to the first and second images to extend the depth of field. An image processing unit (200) may amplify a modulation transfer function contrast in the first and second images. A focal shift between the focal planes may be compensated for. While in conventional approaches for RGBIR sensors contemporaneously providing both a conventional and an infrared image of the same scene the infrared image is severely out of focus, the present approach provides extended depth of field imaging to rectify the problem of out-of-focus blur for infrared radiation. An imaging system can be realized without any apochromatic lens.
