    摘要: A finite conjugate lens assembly with modular interchangeable components includes a zooming component that includes three independently movable lens groups that are disposed within the lens assembly between a pair of static lens groups. The lens assembly exhibits an etendue of between 0.95 and 4.65 mm2sr.

    摘要: A finite conjugate optical assembly including a core zoom module that includes five optical groups that are configured to provide a ratio of highest to lowest magnification between 5.5:1 and 16:1. A lens attachment module and rear adapter module may be disposed, respectively, on an object side and an image side of the optical assembly. The optical assembly may exhibit an approximate etendue between 0.95 and 4.65 mm2sr, and may have a magnification of 2× or more at one or more points of the zoom. The optical assembly may be configured in accordance with between 6.6 MP and 32 MP image sensors.
