An optical sensor for determining a coordinate of a measurement object is provided which includes a stop element and an illumination apparatus configured to generate an illumination light beam and to illuminate the measurement object through the stop element, a sensor element configured to detect a portion of a detection light beam emanating from the measurement object and to determine an intensity distribution, and an optical element configured to focus a portion of the illumination light beam at one focal point along an optical axis. The optical sensor includes an apparatus configured to vary and set a relative lateral position of the optical axis to the measurement object to determine, for each of first and second focal points, first and second intensity distributions at first and second relative lateral positions and to determine therefrom a distance coordinate and/or a lateral coordinate of the measurement object.
