Catadioptric virtual-zoom optical system |
摘要 |
A zoom optical system utilizes a virtual object relay system in order to obtain compact size in a large aperture instrument while minimizing chromatic aberration. The size may further be reduced by employing limited amounts of special optical materials for some of the lens elements.
