    • A universal folding condenser (1) with a support plate (4), which is fastened on the microscope and has an arm (4') angled off through 90.degree., is described. Arranged in the support plate (4) is a fixed lens (5). Above the support plate (4) there is provided a first, rectangularly shaped swivel arm (7) with a condenser head and a lens element (2) for optional introduction into the path of the illuminating beam (11). Arranged underneath the support (4) is a second, rectangularly shaped swivel arm (8) with a second lens element (3). The two swivel arms (7, 8) are forcibly coupled by means of a shifting linkage (6) in such a way that, for objectives with low magnification, the two lens elements (2, 3) are introduced into the path of the illuminating beam (11) and, for objectives with high magnification, only the condenser head is introduced into the path of the illuminating beam (11).

    • A microscope (1) is described which has an adjustment knob (2) arranged on the microscope (1) and an encoder (6) assigned to the adjustment knob (2). The encoder (6) is connected to a control device (3). The control device (3) is assigned positioning motors (4, 14, 18, 23, 24) for motorized setting of different microscope functions. The preselected function which can be controlled by motor is preselected via switches (7, 11, 15, 19, 21) arranged on the microscope (1) and triggered via the control device (3) as a function of the encoder pulses generated by the adjustment knob (2). The motor drives are assigned sensors (8) which detect the operating position of the activated microscope function. When the maximum operating position is reached, a braking motor (9) connected to the adjustment knob (2) is activated via the control device (3) and renders the rotation of the adjustment knob (2) more difficult up to complete blockage.

    • A positioning control for linearly displacing an object (31) has a direct current motor (1) and a gear (2,21) for converting rotary into linear motion, a current supply (4) of current pulses having given frequency, amplitude and duration; a pole reverser; a rotatable operating element (51) coupled to an angular step generator (5) and a sensor of the sense of rotation. The pulse frequency of the current supply (4) is determined by the angular step generator (5) and the polarity of the pole changer is determined by the sensor of the sense of rotation. The characteristic curve of the speed of displacement of the object (31) as a function of the pulse frequency is kinked, in that for low pulse frequencies the speed increases proportionally slowly, and up from the level of a pulse frequency threshold, the speed increases markedly quicker. The invention is useful for microscope focussing drives.

    • A description is given of an illuminating device for a microscope (1), having a light source (2), an illuminating optical system (3) and an LCD (5) arranged in the illuminating beam path (4). The illuminating light is directed onto the object (6) from the light source (2) via the LCD (5), a transparent/opaque pattern being generated on the LCD (5) by means of a control and calculating device (7). The LCD (5) is arranged in a plane (AP′) which is conjugate with respect to the field diaphragm plane or aperture diaphragm plane (AP) and has a planar matrix composed of individual pixels arranged next to one another and of the same dimensions, the pixels each being constructed such that they can be driven individually to generate an arbitrary transparent/opaque pattern. The control and calculating device (7) is constructed as a computer with a graphics card. The graphics card generates the image signal for driving the LCD (5), it being possible for the image generated on the LCD (5) to be represented simultaneously on a separate monitor (8).
