20100315706 | TUBE UNIT FOR MICROSCOPES - A tube unit for microscopes which has a tube lens, including two components with an intermediate, large air separation and an overall positive refractive power. The air separation is at least half the size of the focal length f of the tube lens. A roof edge mirror or another suitable deflection element is arranged between the two components of the tube lens. The roof edge mirror includes two mirrors which can be tilted with respect to one another, and which is able to be tilted around its roof edge. The tilting movement or the tilting angle of the tiltable mirror or deflection element corresponds to half the tilt or half the tilting angle of the tube or eyepiece viewing system. | 12-16-2010 |
20130003187 | HIGH-APERTURE IMMERSION OBJECTIVE - A high-aperture immersion objective, in particular for confocal applications in fluorescence microscopy and for TIRF applications, having three subsystems of lenses and/or lens groups. The design of the subsystems has made it possible for a relatively large object field of 0.25 mm to be present in the case of a high-resolution numerical aperture of 1.49. Furthermore, improved transparency is possible up to a wavelength of 340 nm. | 01-03-2013 |
20130250069 | DEVICE AND METHOD FOR THE THREE-DIMENSIONAL MEASUREMENT OF AN OBJECT - A device for three-dimensional measurement of an object, with a stereomicroscope of the telescope type, which has a common objective and a first and a second tube lens, a first image sensor, which is assigned to the first tube lens, a second image sensor ( | 09-26-2013 |
20130308201 | OPTICAL INSPECTION SYSTEM WITH A VARIATION SYSTEM CONSISTING OF FIVE LENS GROUPS FOR IMAGING AN OBJECT INTO INFINITY - The invention relates to an optical inspecting system designed to image an object to be inspected with a variable imaging scale, comprising a variation system for imaging the object into infinity, a lens group downstream of the variation system for imaging the object from infinity into the image plane of the whole system, and a light source for generating light in order to illuminate the object, means for imaging the illuminating light into the exit pupil of the variation system being provided in the airspace between the fifth lens group and the subsequent lens group. Of the five lens groups of the variation system, the first, second, and fourth lens groups, when seen in the imaging direction, are arranged in a movable manner in the direction of the optical axis, whereas the third and fifth lens groups are not movable. | 11-21-2013 |
20150219886 | OPTICAL SYSTEM FOR DIGITAL MICROSCOPY - An optical system for digital microscopy having at least one lens, at least one telescope of the Kepler type and tube optics, wherein an aperture is arranged between the telescope and the tube optics, which aperture is imaged by means of the telescope at the rear focal point of the lens and the following conditions are met simultaneously:

20150219887 | HIGH APERTURE IMMERSION OBJECTIVE - The invention relates to a high aperture immersion objective particularly for uses in confocal microscopes where oil is the immersion fluid, which objective is composed of three lenses and/or subsystems comprising lens groups. An apochromatic correction in a range from 365 to 900 nm is achieved at high resolving numeric apertures of 1.3 to 1.4 and an object field from 0.4 to 0.625 mm by the specification of the optical components. Additionally, the immersion objective has sufficiently good transparency up to a wavelength of 340 nm. | 08-06-2015 |
20150248001 | APOCHROMATIC MICROSCOPE OBJECTIVE - An apochromatic microscope objective, including three optical sub-systems, wherein starting from the object plane, the first sub-system includes a meniscus and a convergent lens, wherein the meniscus is curved towards the object plane, the second sub-system is made up of three elements, wherein a first element includes a meniscus or a cemented element, a second element is configured as a collecting cemented element and a third element is a cemented element, and wherein either the first element or the third element is strongly scattering and the third sub-system has at least one cemented element with a collecting lens. | 09-03-2015 |
