20110037947 | Illumination device as well as observation device - Disclosed are an illumination device for an observation device comprising one, two or more observation beam paths with one respective beam of observation rays, especially for an ophthalmologic surgical microscope, and a corresponding observation device. Said illumination device is provided with at least one light source for generating at least one beam of observation rays in order to illuminate an object that is to be observed. According to one embodiment of the invention, at least two partial bundles of illumination rays are provided, each of which extends coaxial to a corresponding beam of observation rays, while the partial beams of illumination rays are embodied so as to form two or several illumination spots on the fundus of an object that is to be observed, e.g. an eye, said illumination spots having variable sizes, thus allowing the illumination beam to cooperate in a precisely defined manner with the observation beam paths, which makes it possible to meet especially the practical requirements regarding homogeneity of the red reflex. | 02-17-2011 |
20120147460 | SYSTEM FOR WAVEFRONT ANALYSIS AND OPTICAL SYSTEM HAVING A MICROSCOPE AND A SYSTEM FOR WAVEFRONT ANALYSIS - An optical system, comprising a microscope housing having a coupling opening for a detachable coupling of an objective lens of the optical system such that the objective lens is arranged in a microscope beam path of the optical system for imaging an object region of the objective lens. The optical system further comprises an assembly. The assembly comprises an assembly housing having a coupling element for the detachable coupling of the coupling element and the coupling opening of the microscope housing; a wavefront analysis system, which provides a wavefront beam path; and a beam splitter, which is arranged in the wavefront beam path. The objective lens, the beam splitter and the wavefront analysis system are arranged such that during the coupling of the coupling opening and the coupling element, the objective lens is arranged in the microscope beam path and the object region is arranged in the wavefront beam path. | 06-14-2012 |
20150370059 | STEREOMICROSCOPE HAVING A MAIN OBSERVER BEAM PATH AND A CO-OBSERVER BEAM PATH - A stereomicroscope including a stereoscopic main observer beam path having a main observer zoom system, a stereoscopic co-observer beam path having a co-observer zoom system, and a main objective common to the main observer beam path and the co-observer beam path. The co-observer beam path is coupled out from the main observer beam path via a geometrical beam splitter arranged between the main objective and the main observer zoom system, wherein in the co-observer beam path the co-observer zoom system succeeds the geometrical beam splitter and is constructed from lenses having dimensions such that both a first and a second stereoscopic partial beam of the co-observer beam path in each case pass through the lenses. | 12-24-2015 |
20150374235 | ILLUMINATION DEVICE FOR AN OPTICAL VIEWING APPARATUS - An illumination device for an optical viewing apparatus defines an illumination beam path and includes an illumination light source having mutually independently controllable individual light sources arranged in a first plane in a two-dimensional array. The illumination device defines an illumination beam path and includes illumination optics defining an optical axis. The illumination optics form a second plane conjugated with respect to the first plane. A diaphragm unit is arranged in the second plane. The diaphragm unit has a plurality of apertures and the apertures are assigned to corresponding ones of the individual light sources. | 12-31-2015 |
20150378142 | ILLUMINATION DEVICE FOR AN OPTICAL VIEWING APPARATUS - An illumination device for an optical viewing apparatus has a light source including a first individual light source and a second individual light source arranged in a plane. The first individual light source has a first midpoint and the second individual light source has a second midpoint. An axial direction is defined by a vector from the second midpoint to the first midpoint. An illumination optical unit defines an optical axis which is arranged perpendicularly to the plane and intersects the plane at an intersection point. The light source is imaged toward infinity by the illumination optical unit. The first individual light source has an extent along the axial direction. The midpoint is offset by an amount (Δ) in a positive direction along the axial direction relative to the intersection. The relationship 0.1*L | 12-31-2015 |
