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
