Number: 359/714
Name: Optical: systems and elements > Lens > Including a nonspherical surface > Having five components
Description: Subject matter wherein the lens comprises five sections (i.e., components), each containing two refractive surfaces arranged in series along the optical axis of the lens with their optical centers in alignment thereon, their planes perpendicular to such axis, and their axially extreme refracting surfaces so spaced along the optical axis that parallel light rays upon entering and passing through all of such components are refracted to a focus no more than one time.
