Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to a laser rangefinder with a coaxial emitting optical axis and a receiving optical axis. Background technique [0002] A laser distance meter is a measuring device for a laser distance measuring system, comprising an electro-optical component designed as a beam source, a further electro-optical component designed as a detector, a transmitting optics and a receiving optics. The beam source and transmitting optics are called the transmitting device; while the detector and receiving optics are called the receiving device. The beam source emits a laser beam along an optical axis. The laser beam is focused by the transmission optics and directed at the target object. The reception beam reflected and / or scattered by the target object is shaped by the reception optics and directed along an optical axis to the detector. The measuring devices are divided into paraxial configura...
