Abstract

Improvements in the devices for securing contact lenses or the like for the measurement of their radii of curvature with the aid of a current optical instrument for measurement of curvature, which are characterized in that they can be arranged fixed with respect to the curvature measuring instrument that in the area of the path of the pi rays from the curvature measuring instrument has a downwardly adjustable mirror and in which in the area of the optical axis of this path of rays directed downwards there is provided an adhesive attachment of the contact lens to measuring, characterized in that the adhesive fastener rotates around a horizontal orientable axis preferably parallel to the axis of the curvature measuring instrument in the area of the central points of the curvature of the surfaces to be measured and which is arranged in an adjustable manner in the direction of this axis.
