Optoelektronische Vorrichtung

摘要

. The appliance (1) has at least one light beam (2), transmitter (3) and/or receiver (5) integrated into a housing. Over a part of its periphery the housing (7) is spherical in shape, and over this section can rotate in a holder (8) and can be locked in a predetermined position. . A lens can be fitted in the front of the housing through which both incoming and outgoing light beams pass. The beams can be directed coaxially through the lens. Behind the lens a prism can be provided which directs the light beam emitted vertically from the transmitter in the direction of the lens.
