English Top > Product Information > Optical Devices & Components Top > Aspherical Elements 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. Hybrid Aspherical Elements Contour Convex, Concave Accuracy of Aspherical Layer 1.5 - 2.0μm (with an element of ø40 - ø60mm) Diameter Range ø8 - ø60mm Ground Aspherical Element Contour Convex, Concave & Bi-Aspherical Accuracy of Aspherical Layer < ø1.0μm Curvature >10R Diameter <ø100mm Aspherical Mirror Contour Concave Accuracy of Aspherical Layer <±1.0μm Curvature >30R Diameter <ø35mm Reflectance >92% (silver coated)
