C.5THE ART OF BLOCKING WECO The Vision of Progress

WECO preparation C.5 Best in job To ensure a good quality in glazing, a perfect centering and blocking device is needed. Because of its long tradition in edging spectacle lenses, WECO knows the importance of job preparation. This is why the WECO C.5 offers more than just fully automatic centering and blocking of lenses in order to dramatically reduce the risk of manual interference. One of the additional processes offered by the Weco C.5 is the optical tracing. Faster than mechanical tracing, it also enables a reduction in shape deformations.

Multiple performance Automatic Centering and Blocking Centering of a single vision lens is achieved automatically by built in power measurement. When processing a single vision lens WECO C.5 performs an optical analysis to detect the optical centre as well as the cylinder with its corresponding axis position. With bifocal lenses, the lens image analysis is performed by determining the near vision segment, Progressive lenses are processed by identification of the markings. The layout and lens type detection take place automatically. Most lenses will require no further preparation. Sd...
