Optical Lens: A lens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the beam. A simple lens is a lens consisting of a single optical element. A compound lens is an array of simple lenses (elements) with a common axis; the use of multiple elements allows more optical aberrations to be corrected than is possible with a single element. We provide various kinds of coating on optical lens according to your requirements.Shape: Biconvex, Plano, Plano-convex, Positive Meniscus, Negative Meniscus, Plano-concave, Biconcave Material: Optical Glass Diameter: within 1.5 meters Effective aperture: >90% Color: customized Surface quality: 40/20 Coating: anti-reflection, high reflection , broadband pass, IR-cut, UV-cut
