Composite prism for multi-functional telescope, and binocular telescopic optical system for same

摘要

A composite prism for a multi-functional telescope, and binocular telescopic optical system for same. The composite prism comprises a first half-penta prism (2), a roof prism (3), and a second half-penta prism (4). Elongated right-angled surfaces of the first half-penta prism (2) and second half-penta prism (4) are adhered to a base surface of the roof prism (3). A light incoming surface of the roof prism (3) is the same as a light emitting surface thereof, and is parallel to the roof of the roof prism (3), such that an incoming light axis and an outgoing light axis of the composite prism are parallel. A binocular telescopic optical path system comprises an object lens (1), the composite prism, a reticle lens (5), and an ocular lens (6), and has functions of viewing, aiming, laser emitting and receiving, and display.
