Abstract
A distance measuring device comprises a measuring head, the measuring head having an optical measuring system for carrying out an optical measurement process on a measurement object by means of at least one measuring light beam formed from a broad-band measuring light. The measuring head further has a liquid guide with a liquid inlet and a liquid outlet for producing a jet of liquid directed at the measurement object, the liquid guide being designed such that in certain sections at least the measuring light beam runs essentially along the jet of liquid. The measuring head further has a flow element with a laminar flow channel, the flow element being designed such that the at least one measuring light beam is able to reach the measurement object by passing through the laminar flow channel.
