Class Information
Number: 359/733
Name: Optical: systems and elements > Lens > With reflecting element > Multiple component lenses
Description: Subject matter wherein the lens comprises multiple 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.
