Spherical lenses have at least one surface with a constant radius of curvature. There are two categories of spherical lenses: Convex (Converging) and Concave (Diverging).
The manufacturing process of spherical lenses begins with a quote created by a Manufacturing Engineer. The Manufacturing Engineer then designs and orders a near net shape optical glass blank. The optical glass blanks are then delivered to the production line once we receive the material. Once we process the order, the first step is to have diamond ring tools to generate the radius into the glass blank. A series of progressively smaller grit diamond wheels or loose abrasive material is then used to grind the lens blank finely. Finally, the polishing process uses pitch or polyurethane pads and a cerium oxide slurry to finish the spherical surface. The finished optical lenses are then either shipped to the customer or retained in the facilities for further treatment with processes such as custom coatings and truncations.
