Abstract (en)
[origin: WO03046604A2] Disclosed is a measuring device for contactless distance measurement, comprising an optical transmission path (12) with an optical transmitter (22) and an optical reception path (13) with a receiver lens system (29) and an optical receiver (30), in addition to a device module (11) receiving components from the transmission and reception paths (12, 13). In order to maintain high measurement accuracy for the entire temperature range, the components of the transmission and reception path .(12, 13) are placed in such a way that when the temperature causes the device module (11) to curve in the direction of the optical axes (121, 131) of the transmission and reception path (12, 13), the optical axes (121, 131) are shifted by an equal amount in the same direction. Preferably, the transmission and reception paths (12, 13) are folded in such a way that the transmitter (22) and receiver (30) are jointly disposed on a planar fixing surface, preferably a printed circuit board (15) for receiving electronic components, which is secured in the device module (11).
