Patent ID: 7545492

Claim:
An apparatus comprising: a sighting device for the production of an optically perceptible target marking on an object, said sighting device comprising: one or more light sources for providing at least two sighting rays; and at least two optical components that each split a respective one of said sighting rays into a respective illumination plane such that at least two illumination planes are provided; wherein the at least two illumination planes intersect at an angle and form a target marking; and a measuring device, which interacts with an object of any type at a predefined target location which is set by means of the sighting device, and wherein said measuring device is used with or without contacting the object; wherein said measuring device comprises a detector onto which electromagnetic radiation emitted from a measured spot on the object is imaged by means of imaging optics; and wherein each of said optical components splits a respective sighting ray into a respective fan ray having a lateral edge, wherein the lateral edges are configured such that the fan rays visualize said measured spot diameter.
