1. An apparatus for inserting a measurement light beam which can be projected onto a target object, the apparatus comprising:
a measuring telescope;
a light-refracting component having an optical axis, whereby the light-refracting component is used as an objective lens of the measuring telescope;
at least two mirrors for deflecting the measurement light beam; and
an optical overall body comprising at least one optical material,
wherein the optical overall body is configured in such a way that the at least two mirrors are fitted inside or at the edge of the optical overall body, such that the measurement light beam entering the optical overall body is offset parallel to the incident measurement light beam when emerging from the optical overall body, such that the emerging measurement light beam lies on the optical axis of the light-refracting component of the apparatus and is projected in this form onto the target object,
wherein the apparatus is configured as a coordinate measuring device for measuring range and direction or angel to a point of the target object.
