Lens Blocking Method for Opticam

Not Accessible

Your library or personal account may give you access


A uv-curing 'cold' blocking adhesive has been developed by Loctite Corporation for use with the Opticam SM. The adhesive is a significant advance in the lens blocking process, as it eliminates heat-induced blocking strain; the most significant problem encountered with current hot pitch blocking methods. The new cold blocking adhesive is complemented by a new Kennametal lens blocking adapter tool and chucking system. The tooling offers substantially improved lens adapter to machine alignment and transfer, at considerably lower cost. The lenses are deblocked in a heated water and detergent solution, eliminating the environmental concerns of the current method.
