1. An optical measuring device, comprising:
a measuring head comprising imaging optics and an evaluation unit, the measuring head defining a recess,
wherein the measuring head is connected to the evaluation unit by two light-conducting fibers,
wherein the evaluation unit comprises a light source, the light of which is guided into the measuring head through a first light-conducting fiber of the two light-conducting fibers,
wherein light reflected from an object to be measured is guided back through the measuring head and into a second light-conducting fiber of the two light-conducting fibers by means of a beam splitter such that outgoing and return light are separated,
wherein the fiber ends are located in conjugate positions with respect to each other,
wherein the beam splitter and the fiber ends are arranged together in a connector that is separably connected to the measuring head, the connector being positioned within the recess, and
wherein the connector is configured to be detached from the measuring head and then, in the same condition, reattached to the measuring head.
