Standard Accuracy Precision Polished Aspherical Lenses, D=50.00mm, F=50.00mm, AR@1000-1650nm, United Optical Technology Co., Ltd (CAT#: STEM-OP-1313-YJL)

Standard Accuracy Precision Polished Aspherical Lenses, D=50.00mm, F=50.00mm, AR@1000-1650nm, model 140626, is manufactured by United Optical Technology Co., Ltd.
Standard precision precision polished aspherical lenses are different from molded aspherical lenses. They are lenses made using precision polishing processing methods. They can produce large diameter (≥ 10 mm) aspherical lenses with smaller aspherical surface errors. The surface of an aspherical lens is optimized to use a more complex outer surface, and the curvature gradually changes from the center of the lens to the outside of the lens edge to reduce spherical aberration. When focusing the collimated beam, it should be incident on the aspherical side of the lens, and when collimating the light emitted by the point source, it should be incident on the lens plane to achieve minimal spherical aberration.
