Abstract
A measuring apparatus (1) for contactless detection of a distance between a surface (7) of a measurement object (8) and the measuring apparatus (1), and for simultaneous contactless visual detection of the surface (7), has a measuring head (2) holding a distance measuring device (4), a camera apparatus (5) and an illumination device (6), the illumination device (6) illuminating an operating point (9) on the surface (7) of the measurement object (8) that is simultaneously focused by the camera apparatus (5) and the distance measuring device (4). On an optical axis (10), between the illumination device (6) and the operating point (9), a mirror and filter device (11), that has at least one dichroic mirror (12) that transmits or reflects light beams as a function of wavelength, and thereby splits light reflected by the operating point (9) between the distance measuring device (4) and the camera apparatus (5), is provided.
