Extensive assortment and quick turn-around time
Master Test Plates
A pair of Test Plates constitutes the master standard for curvature and/or perfect flatness. Spherical Test Plates consist of a concave and convex pair, while Flat Test Plates are comprised of three flat plate units.
Production Test Plates
A set of Test Plates is used for inspection of lens elements at the production line. It is replicated from the master. As the pertinent surface sustains wear and tear and/or damage after a period of use, a precisely replicated replacement is produced from the very same master.
