Attachment of optical microscope components

A device for attaching a first optical microscope part to a second part and permitting transmission of at least one of data and electricity supply, the device comprising:

• an annular receptacle attached to the second part;
• a corresponding annular insertion part comprising a lower side, wherein the insertion part is attachable to the first part oriented such that the lower side of the insertion part faces away from the receptacle and wherein the annular insertion part comprises retaining projections, the retaining projections including outwardly sloping retaining surfaces on the lower side of the insertion part,
• wherein the receptacle includes a base ring with a retaining collar, the retaining collar having an inner slanting face tapering away from the base ring and in which a lateral opening is formed, through which the insertion part can be inserted into the receptacle such that it is in a pre-locked position in which the annular openings overlap,
• wherein the insertion part and the receptacle are movable by reciprocal rotation from the pre-locked position into a locked position in which the retaining surfaces of the retaining projections of the insertion part are seated against the inner slanting face of the retaining collar to press the insertion part onto the base ring, whereby the insertion part is locked to the receptacle, and
• wherein the upper side of the insertion part facing the base ring includes planar elements forming a three-point bearing.
