Abstract
Some embodiments of the invention may relate to an optical surveying device having a base for setting up the surveying device and a targeting unit, which is rotatable in relation to the base about two axes, and which defines a target axis or targeting a target object to be surveyed. In some embodiments, the targeting unit has a first beam path for emitting optical radiation in the direction of the target object to be surveyed and a second beam path for receiving a component of the optical radiation, which is reflected from the target object, by way of an optoelectronic receiving element. In some embodiments, at least one of the beam paths, has an optical element, which is implemented having an optically transparent, deformable volume body, and which has at least one interface toward a medium having an optical index of refraction deviating from the volume body.
