Dynamic focus and zoom system for use with wide field of view, confocal and multiphoton microscopes

摘要

A dynamic focus and zoom system is disclosed in which three MEMS mirrors, three prisms, three beamsplitters, three fixed lenses, and an optical relay are all in the housing. The second prism, the first and second fixed lenses, and the first beamsplitter are linearly aligned along the longitudinal axis of the optical relay. The first and second MEMS mirrors are linearly aligned with each other at a 90 degree angle to such a longitudinal axis. The third MEMS mirror, the third fixed lens, the third wave plate, the third beamsplitter and the third prism are linearly aligned with each other at a 90 degree angle to the same longitudinal axis. The third prism abuts the center of the optical relay between the first fixed lens and the second fixed lens, and aligns linearly with the first prism such that the linear alignment of the first prism and the third prism is parallel to the longitudinal axis of the optical relay. do.
