Abstract:
1. A measuring assembly for optically measuring an inside of a lens frame of a spectacle frame, said lens frame at least partially delimiting an inscribed surface area F that corresponds to a lens shape, comprising a holding device for mounting the spectacle frame, at least one light source for generating a light beam to be projected on a region of the lens frame to be evaluated, and at least one sensor that can be coupled with an evaluation unit for detecting the reflected light beam, wherein the holding device and the light source can be rotated relative to one another about a rotational axis r and moved in the direction of a movement axis x, and the movement axis x comprises at least one movement component in a direction perpendicular to the rotational axis r, wherein the holding device comprises at least two clamping element for fixating the lens frame, said clamping elements being movable in a direction of a movement axis y comprising a movement component at right angles to the movement axis x and comprising a movement component at right angle to the rotational axis r, and said clamping elements being pretensionable against the spectacle frame.
