Embodiment Construction

[0016] As shown in the accompanying drawing, it is an optical system of a light inspection scope. This embodiment is the case of applying the present invention to a 3-12x50SF gun scope.

[0017] Along the direction from the object side to the image side, the optical system includes an objective lens group 1 , a relay lens group 2 and an eyepiece group 3 arranged in sequence.

[0018] The objective lens group 1 includes a plastic aspheric lens 11, and the plastic aspheric lens 11 includes an aspherical surface and a diffractive surface. The objective lens group may also include a glass lens sheet 12, and the plastic aspheric lens 11 and the glass lens sheet 12 are arranged in sequence along the direction from the object side to the image side. The glass lens sheet 12 is a plano-concave single lens. The transfer lens group 2 and the eyepiece group 3 are known technologies, and will not be described in detail in this embodiment.

[0019] In this embodiment, along the direction...

Abstract

The invention discloses an optical system of a sighting telescope for a portable gun, comprising an objective set, a transferring lens set and an eyepiece set which are successively arranged from the object side to the image side, wherein the objective set comprises a plastic aspheric surface lens, and the plastic aspheric surface lens comprises an aspheric surface and a diffraction surface. On the premise of ensuring optical quality, the invention reduces the amount of objective set lenses and lowers the weight and the cost of the whole system.

Description

technical field [0001] The invention relates to an optical system of a scope, in particular to an optical system of a scope for a gun. Background technique [0002] At present, the military and civilian gun sights with side adjustment used at home and abroad also use an optical system consisting of an objective lens group, a relay lens group and an eyepiece group, and the objective lens group is composed of glass lenses. The structure is composed of a doublet lens group and a single piece lens, or a doublet lens group and two singlet lenses, the doublet lens group is mainly used to reduce the chromatic aberration of the objective lens, and a singlet lens is mainly used for The internal focus of the gun sight system. Because the objective lens group is all made of glass material, and the objective lens caliber is relatively large, so the volume and weight of the objective lens are relatively large, which brings certain inconvenience to the use and carrying of the scope.
