Abstract:
1. A measuring device for contactless distance measurement, in particular a handheld device, having an optical transmission path ( 12 ), which has an optical axis ( 121 ) and as one component has an optical transmitter ( 22 ), having an optical reception path ( 13 ), which has an optical axis ( 131 ) and as components has a receiving optical element ( 29 ) and an optical receiver ( 30 ), and having an equipment module ( 11 ) that receives the components of the transmission and reception paths ( 12 , 13 ), characterized by a placement of the components of the transmission path ( 12 ) and reception path ( 13 ) such that upon a temperature-caused curvature of the equipment module ( 11 ) in the direction of the optical axes ( 121 , 131 ) of the transmission and reception paths ( 12 , 13 ), the optical axes ( 121 , 131 ) are deflected by the same amount in the same direction.
