摘要:
The present invention relates to a microscope (100) having an illumination unit (4) for generating an illumination beam path (4b, 4a), the microscope (100) comprising a main objective (2) that defines an observation beam path (17a) and comprising at least one deflection element (5, 6, 7) for deflecting the observation beam path (17a), at least one of the deflection elements (5, 6, 7) being embodied as a micromirror array (5′) having individually controllable and adjustable micromirrors (50), the micromirrors of the micromirror array (5′) being adjustable in such a way that in addition to the observation beam path (17a, 17b), the illumination beam path (4a, 4b) also proceeds via this micromirror array (5′).

The invention concerns a surgical microscope (2, 3, 5) having a novel laser illumination system (11) and, in a preferred embodiment, an arrangement in which a diffractive element (7) produces an additional illuminating beam and a measurement beam.
摘要:
An optical magnification device for varying the distance between an observer's eye (1) and an object (7), e.g., for a binocular magnifier or a microscope, in which focusing onto the object (7) is accomplished by means of progressive lenses (3) displaceable perpendicular to the observation beam(s) (2).
摘要:
The invention relates to an apparatus for illuminating a viewing field, for example a specimen (10) under a microscope (7), by means of at least two light sources (1a, 1b). The illumination apparatus comprises an apparatus for measuring the brightness of the light sources (1a, 1b). The result of this measurement can be transmitted to the observer (9), either acoustically or visually, via a computer (4) that compares the signal with a definable threshold value. The beam paths (103, 104) of the two light sources (1a, 1b) are guided via a combining light-guide coupler (109), a common light guide (2), and a separating light-guide coupler (111) having two light-guide arms (112, 15), one of the two light-guide arms (112) being delivered to the microscope (7) as a main light source, and the other light-guide arm (15) to a handpiece (16) as a second light source of the microscope (7). At least one of the two light sources (1a, 1b) is configured as a changeable unit (illumination changer), and at least one of the input light-guide arms (107, 108) is configured as a changeable unit (light-guide changer).

The invention concerns an illumination apparatus for an optical observation device (10), in particular a stereomicroscope or a stereo surgical microscope. A multi-armed light guide with coupler (2) mixes colored light emitted by light-emitting diodes (1a–c) to yield white mixed light (15).

The invention relates to an optical device (500) with a device (600) for increasing the depth of field having at least one optical element (3) with different focal lengths (f1, f2).
摘要:
The invention concerns a zoom system, having various materials (glass types) and variable air spaces, for example for a surgical (stereo)microscope, constructed from four symmetrically arranged lens groups (2 through 5), each two lens groups (2, 5; 3, 4) being arranged identically and in mirror-image fashion with respect to one another. As a result of the special selection of glass types having anomalous partial dispersion, and the specific design features, a high zoom factor is achieved with a short overall length, as well as good correction of the secondary spectrum, astigmatism, and field curvature.
摘要:
A microscope, which may be a stereomicroscope, includes: at least one objective; at least one eyepiece; at least one optical component configured to form a beam path from the objective to the eyepiece, where each optical component includes a lens, mirror, or deflection prism; and a tube configured to enclose a portion of the beam path, including at least one region of modifiable length configured to connect to at least one optical correction element and configured so that the optical correction element may be inserted into or removed from the portion of the beam path. The microscope may include a linkage between the tube and the correction lens configured to pivot or slide the correction lens as a function of a length of the region of modifiable length.
摘要:
For optimizing the perception of the red reflex in eye operations, deflecting elements are arranged in the illuminating beam path in the illuminating device of an operation microscope with optically-mechanically coupled observer and co-observer tubes. The deflected illuminating beam pencils overlap, at least partially, the main observer observation beam paths and at least one of the co-observer observation beam paths.
摘要:
The invention relates to a high-precision autofocusing arrangement for a stereomicroscope wherein a bar-shaped marking is projected via a cylinder optic on an object. The imaged bar-shaped marking is at least in one dimension less or equal to the resolution of the viewing beam path. A region of the objective not used optically is selected for projection as the pass-through pupil.
