摘要：The invention relates to n optoelectronic sensor having a transmitter () for thetransmission of a transmitted light beam () which is extended perpendicular to thedetection direction by means of an optical transmission system () and a receiver () for the
reception of received light () and for the provision of an electronic received signal, and anevaluation unit () for the recording of the received signal and for the outputting of anobject detection signal, wherein at least the transmitter () and the optical transmissionsystem () are arranged in a sensor housing () having a front screen (). To provide animproved sensor which is inexpensive and nevertheless generates a linear transmittedlight of high quality, it is proposed that the front screen () is overlaid with patterns () oflight absorbing material for light intensity homogenization in a region (S) through whichthe transmitted light () passes and/or in a region (E) through which the received light ()passes.
