Precision Polished Aspheric LensesThorlabs offers CNC precision-polished large-diameter aspherical lenses, with and without anti-reflection (AR) coatings. These lenses are available in larger sizes, provide better surface quality, and maintain the M squared values of the input beam better than their molded aspheric lens counterparts. The surface of an aspheric lens is designed to eliminate spherical aberration. They are often employed to collimate light exiting a fiber or laser diode. We also offer acylindrical lenses, which provides the advantages of aspheres in one-dimensional focusing applications.
