title: Simple designs to correct all third- and fifth-order aberrations.
abstract: There have been a handful of optical designs published that correct all of the third- and fifth-order ray aberrations without aspherical elements. These published designs have a minimum of six elements. Presented here are designs with only four and five elements. The performance of the designs and their practical utility are discussed.
