摘要:
A calibration device for managing a variety of performance tests and/or calibration tasks in a laser scanning microscope. The calibration device, which has focusing optics and a test structure arranged in the focal plane of the focusing optics, with structural elements detectable in reflected and/or transmitted light aligned to each other in a common mounting, can be switched into the microscope beam path in a laser scanning microscope, so that the pupil of the focusing optics coincides with the objective pupil of the laser scanning microscope or lies in a plane conjugated to it.

The invention is directed to a darkfield illumination system and is applicable in transmitted light microscopy and in incident light microscopy. A combination with a first, segmented mirror and a second, aspherical mirror is proposed for the purpose of uniform illumination of the large object fields occurring at low magnifications.

A device for attaching a first optical microscope component part to a second part includes an annular receptacle attached to the second part and an annual insertion part. The annular insertion part includes outside-conical retaining projections. The receptacle includes a base ring having a retaining collar with an inside cone tapering away from the base ring and in which a lateral opening is formed, through which the insertion part can be inserted in the receptacle such that it is located on a pre-locking position in which the annular openings overlap. The insertion part and the receptacle can be moved by reciprocal rotation from the pre-locking position into a locking position in which the outside-conical retaining projections of the insertion part are seated against the inside cone of the retaining collar and press the insertion part on the base ring, whereby the insertion part is locked to the receptacle.
摘要:
An arrangement for equalizing binocular visual fields for microscopes and other optical instruments, with an eyepiece arranged in each beam path, and with diaphragms serving the purpose of visual field adjustment. The diaphragms are fixed or movable in or in immediate proximity to an intermediate image plane in the optical output to the left eye and/or to the right eye. One diaphragm is arranged eccentrically or concentrically in the installation space of at least one eyepiece or in at least one eyepiece support of the corresponding optical instrument provided therefor. Adjusters are present for positioning and/or adjusting the diaphragms.
摘要:
An immersion microscope objective includes a system of several optical lenses or lens groups between which air spaces are provided and an adjusting device for adapting the immersion microscope objective to different immersion mediums for correcting imaging errors when utilizing the immersion microscope objective in connection with a cover glass, which closes off a specimen holder, and/or for correcting longitudinal chromatic aberrations. The adjusting device is configured to change two air spaces and especially the air spaces (A1, A2) are linearly changeable.

The invention relates to a slider for introduction into an optical path of a light microscope. Such a slider has a housing for arrangement on the light microscope, a holder which can be displaced in the housing in a displacement direction over a displacement length, an optical element which is held by the holder oriented with respect to an optical axis extending perpendicular to the displacement direction, and movement means for displacing the holder. The slider is characterised according to the invention in that at least the portion of the movement means which lies in the displacement direction within the displacement length lies, in a direction perpendicular to a plane fixed by the optical axis and the displacement direction, completely within a coverage area which is covered by the holder upon displacement thereof, wherein the coverage area is fixed by the optical axis as normal.
摘要:
An objective lens assembly is provided, with a sleeve, a first positioning member arranged in the sleeve, which is housed displaceable in longitudinal direction of the sleeve and holds at least one lens, a first adjustment unit which brings the first positioning member into abutment on the inside of the sleeve such that the first positioning member rests against the inside of the sleeve in a first linear contact area and at the same time the displaceability of the first positioning member is maintained. More than one positioning member can be utilized along with multiple lenses and can utilize simple mechanical structures (e.g., blind- and through-holes and pins or shanks) and/or magnetic or magnetizable materials to maintain a desired position of the sleeve.
