SPHERICAL VS. ASPHERIC LENSES

HOW THEY’RE USED IN IMAGING APPLICATIONS

Optical Lenses are often categorized by their shape. Two common surface shapes are spherical and aspherical. Each offers unique characteristics that make it suitable for different use cases.


An optical defect resulting from design or fabrication error, e.g., coma, distortion, curvature of field that prevents the lens from achieving precise focus.
