Lens grinding

self adhesive film designed for various production steps in the optical industry

This step gives the lens its corrective effect by "carving" the concave side with a diamond head. The lens is either "organic" (plastic) 75 % of the total market, or "mineral" (glass) 25 % of the market.

The single sided tapes of the Optical Film Range OF 2428, OF 2429, OF 2430, OF 2475  have been especially designed for the fastening and protection of lenses during the forming stages
