Abstract

The invention relates to an electro-optical measuring device, in particular a hand-held device (10) for contactless distance measurement, comprising an optical transmission path (28), which has a first optical axis (72) and which has at least one optical transmitter (20) for emitting a measurement signal, and also comprising a reception path (29) having a second optical axis (74), which is spaced apart from the first optical axis (72), with at least one reception optic (32) for focusing a measurement signal in the direction of a receiver (26), and also comprising an optical near range element (60) for parallax compensation. It is proposed that the near range element (60) be embodied rotationally symmetrically with respect to the second optical axis (74).
