Title:
OPTICAL PATH CONVERSION DEVICE AND OPTICAL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/111710
Kind Code:
A1
Abstract:
An optical path conversion device and an optical system. The optical path conversion device comprises: an objective lens assembly (300) and a conversion assembly (200). The objective lens assembly (300) comprises a first objective lens (321) and a second objective lens (322) to respectively form first emergent light (511) and second emergent light (520). The conversion assembly (200) comprises a first conversion mechanism (210) and a second conversion mechanism (220). The first conversion mechanism (210) receives the first emergent light (511) to form first reflected light (512). The second conversion mechanism (220) comprises a driving unit (228) and a reflecting unit (225). The driving unit (228) is connected to the reflecting unit (225) and drives the reflecting unit (225) to move to the optical path of the first reflected light (512), so as to form second reflected light (513) and make the optical path thereof coincide with the optical path of the second emergent light (520). The problem of poor precision caused by conventional structure conversion is solved by optical path conversion, and the reliability of the structure design of the optical path conversion is higher than that of the existing turntable structure, facilitating high-precision multiplicative conversion, facilitating control of the consistency of the optical paths, solving the difference in non parallelism between the objective lenses, and facilitating control of the degree to which the fields of view of the objective lenses coincide.
