Abstract:
A method and a device for measuring the topography and/or the gradients and/or the curvature of an optically active surface of an object are disclosed. The device allows the object to be arranged in a receiving region with a contact surface for contact with the object. Inside the device, there is a plurality of point light sources that provide light that is reflected at the surface to be measured of an object arranged in the receiving region. The device includes at least one camera with an objective assembly and an image sensor for detecting a brightness distribution which is produced on a light sensor by the light of the point light sources reflected at the surface to be measured.

Claim (Index 43):
A method for calibrating an apparatus for measuring at least one of a topography, a gradient, or a curvature of an optically effective surface of an article, the method comprising:\n arranging the article with a holding device in a recording region with an abutment that is placed on the article; providing a multiplicity of light spots that emit light, the light being reflected at the optically effective surface of an article to be measured that is arranged in the recording region; capturing a brightness distribution with at least one camera having a lens assembly and an image sensor, which is caused on an image sensor by the light of the light spots that is reflected at the optically effective surface to be measured; determining the imaging scale and the distortion of the optical imaging system of the camera; arranging a lens element between the recording region and the lens assembly, the refractive power of the lens element being positive or negative, and determining reflections of the light spots on the lens element and suppressing the reflections of the light spots in a brightness distribution, captured in relation to a test object, on the image sensor.
