OBJECTIVE LENS ASSEMBLY HAVING CATADIOPTRIC GROUP

摘要

Provided is an objective lens assembly and, more specifically, relates to a high-resolution objective lens assembly which efficiently compensates color aberrations and monochromatic aberrations, comprising: a catadioptric group; a first refractive lens axially aligned with the catadioptric group; and a focusing lens axially aligned and between the catadioptric group and the first refractive lens. The focusing lens is an aspheric lens.
