ABSTRACT:
A multiple laser beam scanning optical system for correcting monochromatic and polychromatic aberrations comprising a doublet cylindrical lens for receiving the multiple beams and directing them to a rotating polygonal mirror. Scanning lens means are located to receive the beams from the mirror and direct them to the image plane. The scanning lens is comprised of at least one doublet wherein both elements have approximately the same index of refraction but different dispersion factors at a nominal wavelength
