  • An Introduction to the Optics Manufacturing Process

     · Before the lens undergoes further grinding the lens must be blocked or mounted to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax. A lens can be blocked individually (Figure 3a) but more often many lenses with the same radii are mounted on one surface
