Abstract
Some embodiments of the invention relate to a rotation unit for a surveying device, in particular a laser scanner for optically scanning an environment and such a surveying device. The surveying device has a rotation unit having a rotation mirror, for deflecting an emission light beam and a reception light beam, and a rotation body implemented as a cylinder having a on a beveled, free end. The rotation body is implemented as a hollow cylinder having a cylinder bottom and a beveled cylinder wall on its free end. The hollow cylinder is connected coaxially with respect to its cylinder axis in a rotationally-fixed manner to a motor-driven shaft via the cylinder bottom. The rotation mirror is fastened in the region of its free end to the cylinder wall of the hollow cylinder so it is supported thereby.
