Abstract

The invention relates to a device for optically measuring distance, in particular a hand-held device, comprising an transmitter unit (12) which is provided with a light source (17, 18) for transmitting optical measuring radiation (13, 20, 22) to a target object (15), and a capturing unit (14) which is arranged at a distance on the optical axis (38) of the transmitter unit (14). Said capturing unit (14) comprises at least one optical detector (54) comprising a detection surface (66) for capturing optical radiation (16, 49, 50) reflected by the target object (15). According to the invention, the detection surface (66) of the detector (54) comprises an optical near range element (68), whose optically active surface (72, 74) is elongated in the direction (61) of the radiation shift for receding target object separations (48) and expands or has at least one essentially constant extension.
