Abstract
The application relates to an ergonomic tube for a microscope. A binocular head is provided on the tube. A deflection element is provided in the tube and a deflection mirror is assigned to the element, the mirror being located behind the optical path of the lens, when viewed from the user's position. A single tube-lens system is positioned in the optical path of the tube. A modification to the inclination of the oclar optical path in relation to the horizontal (H) by a value αcauses the position of the deflection mirror to be modified by an angle α/2.
Claims16
A tube for a microscope with an objective defining an objective optical path, the tube defining a tube optical path, a binocular head provided at the tube defining an ocular optical path, a deflection element being provided in the tube optical path, wherein the objective optical axis is positioned between a deflection mirror and the binocular head, without intersecting the deflection mirror,
- wherein a one-piece, single tube-lens system is positioned in the tube optical path and a modification to the inclination of the ocular optical path in relation to the horizontal by a value α causes the position of the deflection mirror to be modified by an angle α/2.
The tube as claimed in claim l, wherein the binocular head has two eyepieces, an intermediate image is configured to be created in each of the eyepieces and the distance from a lens vertex of the single tube-lens system to the intermediate image is not greater than 1.25 times the focal distance of the tube-lens system.
