Optoelectronic sensor for detecting precipitation on a vehicle screen, has arrangement for adjusting distance between beam incidence and emission surfaces and inner screen surface on beam guiding body or mounting socket

摘要

The device has a beam transmitter (2) and receiver (3) and a beam guiding body (6) with beam inlet and outlet surfaces (4,5). The inner screen surface (1') is profiled (7') with input and output coupling regions perpendicular to beam incidence and emission angles. An arrangement for adjusting the distance between the beam incidence and emission surfaces and the inner screen surface is mounted on the guiding body or mounting socket.
