摘要:
A microscope with an exchangeable intermediate tube that is inserted between the microscope objective and an ocular eyepiece instead of the tube lens and which is adjustable in a defined manner with respect to its height and has relay or transfer optics with an essentially constant intersection length, comprising, in the observation direction, a first lens group with a long focal length, preferably greater than 10 m, and a second lens group with a short focal length whose common focal length corresponds to the focal length of a standard tube lens, preferably approximately 164 mm, wherein the distance between the first and second lens group is adjustable.

The invention is directed to a temperature-controllable objective, particularly for microscopes and other optical equipment, which comprises a main barrel as the main component part of the objective. The main barrel contains at least one correction mount, cylinder sleeves, mounting rings, carrier rings and/or adjusting rings, and imaging optical elements. In order to control the temperature, at least one structural component part of the objective or an element arranged between structural component parts of the objective is constructed as a temperature-controllable element or as a temperature-controllable foil which is connected (not shown) by leads to a device for monitoring temperature. Further, a temperature gauge or temperature sensor is arranged in the objective and is likewise connected to the device for monitoring temperature.
摘要:
A controller for microscope lenses for correcting spherical aberration and for adjusting particularly difficult to access microscope lenses to an optimum of imaging quality, enabling automatic adjustment of the different actuators of a microscope lens, to effect a simple, cost-effective, user-friendly, and precise balance, particularly of cover slip deviations and different base thicknesses of Petri dishes for the purposes of increasing imaging quality. At least two movable elements of a microscope objective supporting lenses or lens groups, are provided in a movable manner in the axial direction along the optical axis of the microscope objective relative to the housing of the microscope lens in a motor-actuated manner by way of respective adjusting rings. A controller externally controlled and disposed in the microscope lens is provided for storing different characteristic curves for paths of motion of the movable elements.

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.

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.

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:
A microscope objective with high aperture, large object field and apochromatic correction in the wavelength range from ultraviolet to infrared. The microscope objective includes, starting from the object level: a first group of lenses with overall positive refraction power, including a cemented group with positive-negative refraction power effect, made out of one of two lenses, and of a further lens with positive refraction power, a second group of lenses with positive refraction power, including three cemented lenses, a third group of lenses with negative refraction power, including three cemented lenses, in which the side that faces the image plane is convex, a fourth group of lenses, consisting of a lens with positive refraction power and a cemented group of two lenses with positive-negative refraction power, and a fifth group of lenses, including two lenses in a cemented group with negative-positive refraction power.

The present disclosure relates to a family of microscopes, each with at least one lens group that includes at least one lens and a lens mount and moves along the optical axis via a drive system for The drive system includes a rotary motor and transmission elements to convert the rotary motion to linear motion to transmit the translational movement to the lens group, and, simultaneously, to prevent rotations of the lens group about the optical axis. In an embodiment, the rotating output shaft of the motor is connected with a screw spindle that engages with a threaded hole machined into the lens mount, so that the lens group is directly moved in a translational manner. The engagement of the screw spindle with the lens mount both effects the translational movement of the lens group and secures the lens group against rotation about the optical axis.
