An objective lens mount and a connection device are releasably connected. The connection device is part of an objective lens or an adapter. The objective lens mount has at least one abutment surface that cooperates with at least one counter abutment surface at the connection device. At least two V-shaped first positioning bodies with at least one positioning surface are arranged such that the positioning surfaces face the longitudinal axis. At least one counter positioning surface at the connection device abuts the positioning surfaces of the objective lens mount. The relative position in the circumferential direction is defined via a rotation stop of the objective lens mount that cooperates with a counter rotation stop of the connection device. A locking device retains the connection device at the objective lens mount and effects a force component in the axial direction and preferably a force component in circumferential direction.

Objective lens mount and connection device for replaceable mounting of an objective lens

The invention relates to a holding apparatus for an optical measurement device. The holding apparatus has two holding units for two preferably telecentric optics units of the measurement device. Each holding unit has a first bearing device and a second bearing device. The two bearing devices are arranged at a distance from one another in the direction of an optical axis of the optics unit. A three-point bearing by three bearing elements for the associated optics unit is provided on each bearing device. At least two of the bearing elements can be positioned along a relevant adjustment axis. The adjustment axes extend substantially at right angles to the relevant optical axis. The optics unit can thus be displaced in a plane spanned by the adjustment axes and can be inclined or tilted on account of the two bearing devices distanced from one another.
