Abstract
The invention relates to an ergonomic tube (30) for a microscope (1). A binocular head (20) is provided on the tube (30). A deflection element (15) is provided in the tube (30) and a deflection mirror (18) is assigned to said element, the mirror (18) being located behind the optical path (5) of the lens, when viewed from the user's (17) position. A single tube-lens system (11) is positioned in the optical path (16) of the tube. A modification to the inclination of the ocular optical path (21) in relation to the horizontal (H) by a value αcauses the position of the deflection mirror (18) to be modified by an angle α/2.
Claims17
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, whereby a deflection mirror is provided behind the objective optical path, when viewed from the user's position,
- wherein a single tube-lens system is positioned in the tube optical path and in that 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 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.
