The present invention relates to a surveying apparatus for surveying an object as well as a surveying system comprising the surveying apparatus having a simple and compact optical setup. The surveying apparatus comprises a lens arrangement including at least one movably arranged focus lens element for focusing to sight an object; an imaging unit configured to obtain an image of at least a part of the object; a distance measuring unit configured to measure a distance to the object along the optical axis of the distance measuring unit; and a beam splitter/combiner configured to combine a part of the optical imaging path of the imaging unit and a part of the optical distance measuring path of the distance measuring unit so that the optical axis of the imaging unit and the optical axis of the distance measuring unit are at least coaxially arranged with the optical axis of the lens arrangement between the lens arrangement and the beam splitter/combiner.

Surveying apparatus for surveying an object

Optical system for tracking and visually examining a target, comprising an image sensor and a lens arrangement having a variable position relative to the image sensor to project an image of the target onto the image sensor, a light source for emitting light in a predetermined wavelength range in the direction of the target and a filter switch for switching an optical filter for selectively allowing the light in the predetermined wavelength range to pass through to the image sensor into and out of the optical path to optionally perform a visual examination and monitoring of the tracking. A tracking device is provided to perform the tracking of the target using the reflected light in the predetermined wavelength range in a sequence of images held by the image sensor when the first optical filter is switched into the optical path.
