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

The invention relates to an electronic distance measuring apparatus for surveying, e.g. for measuring the distance from the apparatus to an object. The apparatus comprises: a) an objective lens (), defining an optical axis (OA), b) at least two sources () of structured light for transmitting beams (&#x3bb;, &#x3bb;) of separate wavelengths towards said object, said beams on reflection from said object received by the objective lens (), (c) at least two receivers () arranged outside a beam path () as defined by the objective lens (), and adapted to receive said received beams (&#x3bb;, &#x3bb;) of structured light. Optical means comprising at least two dichroic surfaces () are each arranged at a tilt angle (&#x3b1;, &#x3b1;) with respect to said axis (OA), said optical axis (OA) passing through said surfaces, at least one of said dichroic surfaces arranged on a plate (), said at least two dichroic surfaces () adapted to reflect at least one of said received structured light beams (&#x3bb;, &#x3bb;), respectivly, towards said receivers ().
