Abstract
A system for holding and aligning spectacles such that mapping measurements of the optical properties of a lens can be performed with the lens held such that its optical axis is parallel to the incident measurement beam. This may be implemented using three points which define a plane with which a surface of the lens can be aligned. The frame gripper is constructed such that the lens to be measured is free to rotate in space around any axis until clamped by the three alignment pin support arrangement, with the exception of rotation around the optical axis of the lens. This freedom of rotation allows the lens to be positioned on the alignment pin support automatically without the need for operator intervention. The spectacle frame is clamped using a spring loaded caliper device, configured to sequentially align the mechanical center of each lens with the measuring beam.
