Stage drive for microscopes
View Patent ↗A stage drive for moving a microscope stage designed as a mechanical stage including a first drive element linked to a first output element, and a second drive element, which is linked to a second output element. Through first and second transmission elements, the first output element is linked to a first stage element and the second output element is linked to a second stage element of the mechanical stage supported by the first stage element. The stage elements are supported so as to be displaceable relative to a fixed base element in orthogonal directions X, Y in a plane extending normal to the optical axis of the microscope beam path. The at least one stage drive includes at least one drive element and at least one output element and is arranged in the base element so as to be displaceable in X direction and/or Y direction within an adjustment range and lockable.
1. A mechanical microscope stage, comprising
a fixed base element;
a first stage element;
a second stage element supported by the first stage element; and
a stage drive;
wherein the first and second stage elements are supported to be displaceable relative to the fixed base element in orthogonal directions X and Y in a plane extending normal to an optical axis of a microscope beam path;
the stage drive comprising:
a first drive element linked to a first output element;
a second drive element linked to a second output element;
wherein the first output element is linked to the first stage element by a first transmission element and the second output element is linked to the second stage element by a second transmission element; and
wherein the stage drive is coupled to the fixed base element to be adjustable in location relative to the base element in the orthogonal directions X and/or Y within an ergonomic adjustment range; and
wherein the stage drive is lockable in the fixed base element in a selected ergonomically favorable adjustment position.
2. The mechanical microscope stage as claimed in claim 1 , wherein the stage drive further comprises a first slide supported in first guideways in the base element so as to be displaceable in a first direction; and
a second slide supported in second guideways located in the first slide so as to be displaceable in a second direction orthogonal to the first direction; and
wherein the stage drive is supported by the second slide.
3. The mechanical microscope stage as claimed in claim 1 wherein the stage drive further comprises:
a first lever coupled to the base element so as to be rotatable about a vertical first axis of rotation, the first lever having a first end and a second end, the first end being proximate the vertical first axis of rotation, and
a second lever supported in a pivot joint proximate the second end of the first lever away from the first axis of rotation, so as to be rotatable about the pivot joint and lockable relative to the pivot joint, with the stage drive being arranged at an end of the second lever that is opposite the pivot joint.
4. The mechanical microscope stage as claimed in claim 1 wherein the stage drive further comprises flexible drives, pinion drives, friction gear drives and/or drives that are combinations of the foregoing transmitting forces or torques from at least one of the first and second output elements to the first and second stage elements.
