Spherical lenses have at least one surface with a constant radius of curvature. There are two categories of spherical lenses: Convex (Converging) lens and Concave (Diverging) lens.
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.
