Abstract

The invention relates to a geodetic instrument, in particular a geodetic telescope, for example for a theodolite, or geodetic overview, photogrammetry or axial camera, comprising an imaging optical system which defines an optical axis and comprises an observation beam path for imaging a target object by an eyepiece and/or on a camera sensor, for registering and/or providing an image of the sighted target object. According to the invention, the imaging optical system comprises at least two diffractive optical elements in the observation beam path.
