Design, Fabrication, and Testing of Aspheric surfaces
Design, Fabrication, and Testing of Aspheric surfaces Introduction Aspheric lenses have become synonymous with high-performance optics. They are used in an optical design to correct aperture dependent aberrations (spherical aberration), to correct field dependent aberrations (distortion and field curvature), to reduce weight, to make optical systems more compact, and in some cases to reduce cost.
