| description | A mobile device for close-up -photography or -video-recording is so designed that it is easily useable for the investigation of surface details of an object which is particularly large and soft, for example human skin. When placed in contact with the surface of the object, then without further adjustments a sharp and greatly enlarged image is obtained. The device includes a distance-enforcing structure between the optical system and the object which in the object-side focal area ends with a vaulted surface. The vaulted surface is mechanically stiff and is shaped to compensate the image-plane curvature of the optical system by establishing a corresponding object-plane curvature. This compensation enhances the sharpness of the image obtained for an object surface which is pressed against the vaulted surface and thus is positioned in the true object-side focal area of the optical system. |
