B270 Optical Glass Plano Convex Aspheric Lens

B270 Optical Glass Plano Convex  Aspheric Lens An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens. Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations. While in principle aspheric surfaces can take a wide variety of forms, aspheric lenses are often designed with surfaces of the form Aspheric Lenses are used to eliminate spherical aberration in a range of applications, including bar code scanners, laser diode collimation, or OEM or R&D integration. Our aspheric lenses are ground and polished on the plano side and precision molded on the aspheric side Technical Specifications: Material BK7…
