Title:
COMMON OPTICAL-PATH RANGE FINDER SCOPE PERFORMING LASER SEPARATION AT FRONT END OF IMAGING LENS
Document Type and Number:
WIPO Patent Application WO/2019/200560
Kind Code:
A1
Abstract:
A common optical-path range finder scope performing laser separation at the front end of an imaging lens, comprising a shell (10), a control module (20), a laser emitter (31), a laser receiver (32), a data display (33), a laser reflection and natural light transmission mirror (41), a concave imaging lens (42), and a red light reflection and natural light transmission mirror (43); an object image hole of the shell (10), the laser reflection and natural light transmission mirror (41), the concave imaging lens (42), the red light reflection and natural light transmission mirror (43), and an observation hole of and the shell (10) are arranged sequentially in a straight line to form a natural light observation optical path; laser light emitted by the laser emitter (31) is reflected by the laser reflection and natural light transmission mirror (41) and then irradiated on a scene to be detected; the reflected laser light is reflected by the laser reflection and natural light transmission mirror (41) and is received by the laser receiver (32); a red light emitted by the data display (33) is reflected by the red light reflection and natural light transmission mirror (43) and imaged on the concave imaging lens (42); and a laser optical path of the laser light emitted by the laser emitter (31) after being reflected by the laser reflection and natural light transmission mirror (41) is coaxial with a natural light observation optical path. Said range finder scope achieves that the range finder scope imaging observation optical path, the laser emitting optical path and the laser reception optical path are a common optical path, and also solves the problems of an existing imaging objective lens rear-end common optical-path range finder scope that the nearest measuring distance is far away and the blind area is large due to the refraction and reflection of an inner optical path after the laser emitting optical path passes through the imaging objective lens.
