Arrangement for tilting an illumination carrier on an inverse light microscope
View Patent ↗An arrangement tilts the illumination carrier on light microscopes of the inverse type which include a microscope stand on which an illumination carrier having a light source is attached. The arrangement for tilting the illumination carrier ( 2 ) having a light source ( 3 ) includes an electric motor ( 10 ) with which the tilt movement of the illumination carrier ( 2 ) can be controlled in such a manner that the motor-controlled tilting of the illumination carrier ( 2 ) takes place manually utilizing an actuating element or can be triggered automatically and is stepwise adjustable. A device for damping the tilt movement is provided.
1. An arrangement for tilting an illumination carrier on a light microscope of the inverse type, the light microscope further including a microscope stand having a microscope stage defining an aperture; said microscope stand incorporating integrated optical components for guiding and deflecting a light beam along a beam path; said illumination carrier having a light source mounted thereon for transilluminating an object placed on said stage over said aperture so that said object can be examined, the arrangement comprising:
a motor for tilting said illumination carrier with said light source relative to said microscope stand;
an operator-controlled element for manually or automatically triggering the tilting movement of said illumination carrier;
control means for controlling said motor to effect a controlled tilting of said illumination carrier so as to stepwise adjust said tilt movement in response to an input from said operator-controlled element; and,
damping means for damping said tilt movement of said illumination carrier.
2. The arrangement of claim 1 , wherein said microscope stand has a rearward base body; and, said motor is mounted on said rearward base body.
3. The arrangement of claim 1 , wherein said illumination carrier has a carrier arm supporting said light source; and, said motor is mounted directly in said carrier arm.
4. The arrangement of claim 1 , wherein said microscope stand has a forward portion easily accessible to an operator; and, said operator-controlled element is mounted on said forward portion to facilitate access by the operator.
5. The arrangement of claim 1 , wherein said operator-controlled element is an operator-controlled knob.
6. The arrangement of claim 1 , wherein said triggering of said tilt movement is computer supported.
7. The arrangement of claim 1 , wherein said damping means is a shock absorber.
8. The arrangement of claim 7 , wherein said shock absorber is a gas pressure shock absorber.
9. The arrangement of claim 7 , wherein said shock absorber is a spring element.
