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 method for cultivating a plurality of young plants of different species or variety to form a group of young plants which can be handled as a unit. The method includes providing a plurality of propagation pots, each containing a substrate, which allow roots that form in a propagation pot to grow out at the sides, loading at least one growing container with the plurality of propagation pots such that the propagation pots arranged in each growing container contact one another along a portion of their lateral peripheral surface, introducing at least one cutting or seed into each propagation pot, and allowing roots to form in the propagation pots of each growing container until roots emerging from the sides of the propagation pots have formed a network of roots binding the propagation pots together as a cluster of propagation pots.

The present invention relates to an image stabilization device which is particularly space-efficient and has a quick response time, and which is integrated into an image capture device for an image capture system of a surgical microscope, including a carrier substrate (101, 102) defining a sensor plane, a plurality of optoelectronic image capturing cells (110) arranged, in particular, in a matrix array; and at least one moving means (120) for moving the optoelectronic image capturing cells (110) relative to the carrier substrate (101, 102).
摘要:
Attachment module for a microscope, having an ophthalmoscopic lens (142; 242; 342) and an inverting device (140; 240; 340) for inverting an image of an object (143; 243; 343) that is to be observed generated by means of the ophthalmoscopic lens, wherein the inverter device comprises at least four deflection surfaces (146a, 146b, 146c; 246a, 246b, 246c; 346a, 346b, 346c, 346d) by means of which observation beam paths (102) which emanate from the object to be observed can be introduced into a main objective (110) of the microscope, at least two deflection surfaces being planar and at least two further deflection surfaces being non-planar, particularly spherical or in the shape of free-form surfaces.
摘要:
The present invention concerns a microscope with at least one optical element (21a, 21b) for optional deflection and/or splitting of a beam path passing through the microscope, wherein the at least one optical element (21a, 21b) is fashioned as a micro-mirror array (80) having a number of individually controllable and adjustable micro-mirrors (82).

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 present invention relates to a microscope device (15) having a stand (5) carrying a microscope (1), and having at least one detector (21, 22, 23, 24, 26) for determining the three-dimensional position of the microscope, at least one acceleration sensor (24) being provided on the microscope (5). This permits a drastic reduction in the sensors required. In addition, reliable position sensing can be accomplished irrespective of soiling.

The invention concerns a combined surgical microscope system having a surgical microscope and a retinal diagnostic device of modified configuration having transscleral pulsed illumination.
摘要:
A surgical microscope system (1, 2, 3, 4, 5, 6) having a display (7a-7e). Data essential for the surgical procedure, for example video images, are displayed in the observer's immediate field of view, thus making it unnecessary to turn one's head away from the surgical visual field. Because of its optical properties, the display (7a-7e) can also be attached, for example, on the curved exterior of the microscope body (2) or also on an X-Y coupling (6) that may be present. An rigid OLED display or a flexible OLED display is preferably used.
