Abstract: An optical detection system for detecting a hostile optical component without exposing the surrounding to unnecessary hazards is disclosed. The system comprises a laser unit configured to provide an adjustable laser beam along an optical path to scan for the optic component or to act as jammer by providing a target spoofing; a single aperture for the optical path; a detector configured to detect through the single aperture retroreflections of the laser beam at the optical component; and a camera for detecting through the single aperture potential candidates for the hostile optical component.

Abstract: The present invention is directed to a controllable microscope illumination within a microscope system by which all essential contrasting methods in microscopy can be realized. The illumination device according to the invention comprises a plurality of individual light sources which can be regulated with respect to brightness, wherein these individual light sources are formed as unit cells and form a luminous surface by a periodic arrangement. In an advantageous arrangement, imaging optics are associated with each individual light source in order to magnify the image of the source surface of the individual light source so that the images of the source surfaces of adjacent individual light sources touch. Illumination variants for all of the essential contrasting methods in microscopy can be generated by way of the proposed solution. The proposed LED illumination is electronically switchable, can be regulated with respect to brightness, supplies all colors, is long-lasting and economical.

Abstract: In an automatic microscope, there is the task to satisfy the demand for an economical, compact structure, especially a miniaturization as an essential aspect. The automatic microscope contains an optical system having the following: an illumination field (1) which is at least approximately arranged in the aperture diaphragm plane (ABE) of a condenser (2) and is used for the illumination of the object; an imaging optic (4); and, an image-providing sensor (5) arranged in the image plane of the imaging optic.

Abstract: A method and a device are provided for the immersion and for the cleaning of the front lens of microscope objectives in fully automatic microscope systems, in particular inverted microscopes, for the examination of biological and/or chemical samples by which, besides an automatic immersion process, an automatic cleaning of the front lens of the microscope objective is achieved at the same time at the conclusion of the immersion process. In a method in which water is preferably used as immersion liquid, the immersion liquid is provided at the same time as a cleaning liquid for the automatic cleaning of a front lens of a microscope objective at the conclusion of the immersion process. The device according to the invention for implementing the method comprises a receiving vessel which can be placed on the front lens of the microscope objective.

Abstract: The object in an automatic microscope and a method for true-color image reproduction in automatic microscopes is to provide a monitor image which corresponds to the optical impression of an eyepiece image with respect to color and contrast. According to the invention, the spectral distribution of a light source which can be controlled with respect to brightness and/or color temperature is determined upon initial startup, and the intensity of spectral components is associated with control parameters for the light source. Measurements of the spectral distribution of the light source when operating the microscope and of the ratio of the intensity of spectral components to the control parameters which is determined upon initial startup are used for the regulated control of the light source.
