Embodiment 1

[0038] Embodiment 1: as figure 1 , 2 Shown is a basic embodiment of the monocular and quasi-binocular conversion observation optical device of the present invention, which includes monocular and quasi-binocular systems; the quasi-binocular system includes a left-eye system and a right-eye system; the monocular The eye system includes the space optical axis O-O, optical axis O-O1, and optical axis O1-O1, respectively installed on the optical axis O-O, optical axis O-O1, and optical axis O1-O1. The arrangement is as follows: objective lens group, compensation square glass 6, right-angle reflector 1 7, right-angle reflector 2 8, lens 9, right eyepiece group; the left eyepiece system includes respectively installed in the space optical axis O-O2, optical axis O2 On -O3, optical axis O3-O4, optical axis O4-O5, and optical axis O5-O6, the end of the objective lens group where the light enters is the front end, and the end of the eyepiece group is the rear end. The spatial arrangeme...

Embodiment 2

[0039] Embodiment 2: it is a further technical scheme on the basis of embodiment 1. The objective lens group is a positive refractive power group, and the end of the lens that enters with light is the front end, and the third end of the lens is the rear end, from front to back The order is: lens one, lens two, lens three, lens one and lens two are glued together to form a doublet lens, the focal length is 350mm, and the maximum aperture is 50mm; the beam splitting prism group is formed by gluing two identical right-angle prisms with inclined surfaces The slope of one of them is coated with a splitting film with a splitting ratio of 1:1, and the slope of the other piece is not coated; the slope of the right-angle mirror 7 is a reflective surface, coated with an external reflective film, and the slope is parallel to the splitting surface. Relative to the splitting surface staggered 22 ° angle installation, such as figure 2 -The relative positions shown in serial number 5 and se...

Abstract

The invention relates to a monocular and quasibinocular transformation observing optical device which comprises an objective group, a beam splitter prism group and a corner cube mirror 7 which are installed on the same optical axis O-O, corner cube mirrors 7 and 8 which are installed on the same optical axis O-O1, a corner cube mirror 8 and a right ocular lens group which are installed on the same optical axis O1-O1, a rectangular prism 4, a rhombic prism 15 and a left reflector 16 which are installed on two optical axis O2-O3 and O4-O5 parallel to each other, the left reflector 16 and a left ocular lens group which are installed on the same optical axis O5-O6, and the beam splitter prism group and complementary square glass 6 which are installed on the same optical axis O2-O7, wherein the optical axis O2-O7 is vertical to the optical axis O-O. When the beam splitter prism group is located in the light path of the optical axis O-O, quasibinocular observation is realized; when the complementary square glass 6 is located in the light path of the optical axis O-O, monocular observation is realized. The device provided by the invention observes by monocular and quasibinocular transformation and is adjustable in pupillary distance and oxyoptex.

Description

technical field [0001] The invention relates to an optical device, in particular to a monocular and quasi-binocular conversion observation optical device. Background technique [0002] The visual observation optical system can generally be divided into four structural forms: monocular, true binocular, false binocular, and quasi-binocular. The monocular system is a telescopic system composed of an objective lens group and an eyepiece lens group. When observing, only With one eye, the other eye often needs to be closed. This structural form is widely used in aiming and measuring equipment; the true binocular system is two independent, optical axes composed of an objective lens group and an eyepiece group. The telescopic systems parallel to each other have a strong three-dimensional effect when observing the scene, but the volume and weight of this structure are twice that of the monocular system. Due to the large volume and weight, this structure is only used in telescopes wit...
