Abstract: A distance measuring device comprising an optical transmitter channel for transmitting laser light along a transmitter path and an optical reception channel for receiving laser light along a reception path. At least one optical element including a glass part with a coated surface is positioned in the optical transmitter channel or in the optical reception channel. The glass part includes a glass pane with a thickness below 0.3 mm, with a peripheral edge and with a coating on at least one of the two surfaces, and a ring element. The glass pane is adhesively connected to an end face of the ring element. This distance measuring device shows reduced measuring artefacts and/or reduced optical aberration effects and/or a reduced weight.
