Embodiment Construction

[0075] figure 1 Exemplary profiles of lens L are shown at the beginning and end of the surfacing process. Figure 2A and Figure 2B Known challenges in connecting the lens L with a support block B100 known from the prior art are shown and described in more detail above. image 3 and Figure 4 Different aspects of different embodiments of the invention are shown.

[0076] For example, the first aspect of the present invention relates to the lens support member 100 according to the present invention. Embodiments of the lens support member 100 are image 3 and Figure 4 shown in. The lens support member 100 is suitable for supporting the lens L in the surface processing process. For example, the lens support member 100 may be a jig, chuck, workpiece holder and / or adapter suitable for use during lens surface machining.

[0077] The lens L includes two opposing side surfaces L1, L2. This is shown by way of example in all figures. In the surface machining process, one side...

Abstract

The invention relates to a lens support part and a system and a method for lens surface processing, wherein one side surface (L1) of two opposite side surfaces (L1, L2) of a lens (L) is processed. The lens support component (100) comprises a plurality of support elements (110) movable relative to each other and collectively forming a lens mount (120) having a curvature for supporting the lens on the other side surface (L2) thereof against forces generated in the surface processing process. The lens support component includes an adjustment mechanism (130) for moving at least some of the plurality of support elements relative to each other during processing to adjust the curvature of the lens mount to a defined curvature independently of the lens located on the support elements. The invention also relates to a system (500) and a method for surface-machining at least one of the side surfaces (L1, L2) of a lens using a lens support part according to the invention, respectively.

Description

technical field [0001] The present invention relates to a lens support member for supporting a lens against forces generated in a surface machining process in which one of two opposite side surfaces of the lens is machined. The present invention also relates to a system and method for a lens surface machining process in which the lens support members are used, respectively. Background technique [0002] The current manufacturing of custom spectacle prescription lenses requires a personalized machining process in which lenses can be tailored not only to a single prescription formulation, but also to the customer's skull morphology and the specific geometric features of the customer's chosen frame. [0003] Typically, lens blanks with different front curvatures are used in the manufacture of lenses. Among them, there are lens blanks for diverging and converging lenses. Typically, the front surface of the lens blank is finished so that no curvature adjustment or polishing of ...
