aspherical lens / plastic / visible

Tamron continues to expand the horizons of process technologies from Hybrid (replica), glass molding and ultra-high-precision grinding to plastic injection methods. Coupled with the installation of sophisticated measurement equipment that can render readings down to nanometer order, designated form factors are controlled in the production environment. Throughout the whole development process, from the initial prototype sample to production, geometric shapes of the aspherical surfaces are perfected step by step.
