Description

A kind of cylindricality graticle

Technical field

The utility model belongs to graticle technical field, and in particular to a kind of cylindricality graticle.

Background technique

Graticle is typically mounted on eyepiece focal plane, it is that the thin glass of graduation dense bit line is carved on the surface of one piece of pole book Glass, the optical element being inserted into the eyepiece of an imaging system are etched with graduation dense bit line on graticle, can to A crosshair or concentric ring are superimposed on imaging object, which can be used as reference by location, and can be directed at object to be imaged Body.

Vertical graduation, horizontal graduation and sighting distance graduation pattern are carved on graticle, make graticle can be used to implement positioning, The functions such as measurement distance, measurement dimension of object, mainly calculate distance or dimension of object by being utilized mil formula.It is common Graticle is usually plain film, and optical path straight line penetrates graticle, this kind of graticle can not be used for the plane of visions such as periscope, tank With the occasion of the no longer unified plane of observed object, it is necessary to just be able to achieve refraction of light path and observation ranging by other devices.

Utility model content

The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, and refracted light can be generated by providing one kind Graticle, can be without other refracting means, directly observation object by this kind of graticle.

The utility model is a kind of cylindricality graticle, and the graticle is column, is divided into upper and lower part, described It is adhesive layer between upper and lower part, the upper and lower part is fitted closely by adhesive layer, and the contact surface of upper and lower part is fitting Face；Graduation figure is etched on the binding face, the binding face and column radial direction are angled.

Further, the bottom surface and top surface of the column are transparent surface, and side is frosting.

As a preference, the column be cylindrical body, binding face with ± 5 ° at 45 ° of cylindrical body.

Further, the adhesive layer is cementing layer, and the top and lower part gluing are an entirety.

Further, the graduation pattern is set to binding face center.

The utility model has the beneficial effects that: the utility model is first divided by the way that graticle is made into column structure Upper and lower two parts, process graduation pattern on binding face, then by upper and lower two parts gluing are an entirety, and side is polished Processing forms frosting, top surface, bottom surface light transmission.The surface that top and bottom are mutually pasted is binding face, is integrally formed with column structure Certain angle can be such that optical path reflects inside graticle, and the refraction of light path for being used for optical system aims at.

The frosting structure of side effectively prevents light from scattering, and binding face is wrapped in entire column by special jelly Inside configuration, abrasion caused by capable of being reduced when in use because of wiping, making graticle, the service life is longer.

Detailed description of the invention

Fig. 1 is the perspective view of the utility model cylindricality graticle；

In figure, the top 1-, the lower part 2-, 3- adhesive layer.

Specific embodiment

Further explanation is done to the utility model with specific example with reference to the accompanying drawing:

Embodiment 1

A kind of cylindricality graticle as shown in Figure 1, the graticle are column, are divided into top 1 and lower part 2, described It is that adhesive layer 3, the top 1 and lower part 2 are fitted closely by adhesive layer 3 between upper and lower part 2, the contact on top 1 and lower part 2 Face is binding face；Graduation figure is etched on the binding face, the binding face and column radial direction are angled；It is described Graduation pattern is set to binding face center.

The utility model is first divided into two parts up and down, processes on binding face by the way that graticle is made into column structure Graduation pattern out, then by upper and lower two parts gluing be an entirety, side carry out grinding process, formed frosting, top surface, bottom surface Light transmission.The surface that top and bottom are mutually pasted is binding face, and certain angle is integrally formed with column structure, and optical path can be made to divide It draws intralamellar part to reflect, the refraction of light path for being used for optical system aims at.

Embodiment 2

Binding face and column radial direction are angled, and the angle is according to observation object in actual use and Optical devices Positional relationship is with apart from being determined, in the present embodiment, the column is cylindrical body, binding face with ± 5 ° at 45 ° of cylindrical body, To if it is for general latent acknowledger in above-mentioned angular range, there is a relatively good imaging effect.

Further, the light scattering of graticle side causes that the imaging is not clear in order to prevent, at the bottom of the column Face and top surface are transparent surface, and side is frosting, and the frosting structure of side effectively prevents light from scattering.

Further, the adhesive layer 3 is cementing layer, and it is an entirety that the top 1 is glued with lower part 2.Binding face is logical It crosses special jelly to be wrapped in inside entire column structure, abrasion caused by capable of being reduced when in use because of wiping makes graticle The service life is longer.

The thinking and method of the utility model, there are many method and the approach for implementing the technical solution, and the above is only this The preferred embodiment of utility model, it is noted that for those skilled in the art, do not departing from this reality Under the premise of with new principle, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the utility model Protection scope.The available prior art of each component part being not known in the present embodiment is realized.
