A spherical elastic body with abrasive grains forms parallel grooves on curved lens surfaces for uniform polarizing dye deposition.
A disc restoration device uses rotating pads and a water supply to clean abrasive compound automatically between cycles.
Reference contours transfer defined poses to curved spectacle lenses, eliminating time-consuming tactile sensing during laser engraving.
A carrier device protects lens surfaces and edges during machining using a releasable connecting member.
