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, providing diffraction-limited spot sizes. 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.
