Abstract
The present invention provides a kind of doublet synchronous focusing devices, belong to optical focusing equipment technical field.The doublet synchronous focusing device includes focus adjusting mechanism, two detectors and two object lens；The focus adjusting mechanism is opened there are two pilot hole, and two object lens are separately mounted to the both sides of focus adjusting mechanism the same end, the focusing axis as focus adjusting mechanism；Two detectors are separately mounted on focus adjusting mechanism.The doublet synchronous focusing device can make two object lens synchronous-focusings, and easy to operate, simple in structure.
Description
Technical field
The present invention relates to optical focusing equipment technical field, more particularly to a kind of doublet synchronous focusing device.
Background technology
As modern military technology is growing, traditional single band sight, which takes aim at pattern, cannot meet the need of modern war
Ask, it is increasingly mature with solid micro-optic device and infrared detector the relevant technologies, the sight of image co-registration type take aim at equipment meet the tendency of and
It is raw.In equipment is taken aim in image co-registration sight, object lens pattern mainly has close coupled type, discrete both of which, wherein discrete pattern to have 2
A independent object lens.It is needed during use through the clearer object observing of ability of focusing, if 2 object lens are focused respectively,
It is difficult to make 2 object lens while clearly observing same target, it is therefore desirable to have a kind of focus control can make the same step of doublet
It is burnt.
Invention content
The purpose of the present invention is to provide a kind of doublet synchronous focusing devices, can not be right to solve existing focus control
The problem of doublet is focused simultaneously.
In order to solve the above technical problems, the present invention provides a kind of doublet synchronous focusing device, including focus adjusting mechanism, two
Detector and two object lens；The focus adjusting mechanism is opened there are two pilot hole, and described two object lens are separately mounted to the focusing machine
The both sides of structure the same end, the focusing axis as the focus adjusting mechanism；Described two detectors are mounted on focus adjusting mechanism, and with two
A object lens correspond.
Optionally, described two detectors can detect any position other than 20 meters simultaneously.
Optionally, the focus adjusting mechanism does the processing of aluminum or aluminum alloy hard anodizing.
A kind of doublet synchronous focusing device, including focus adjusting mechanism, two detectors and two are provided in the present invention
Object lens；The focus adjusting mechanism is opened there are two pilot hole, and two object lens are separately mounted to the both sides of focus adjusting mechanism the same end, as tune
The focusing axis of focusing mechanism；Two detectors are mounted on focus adjusting mechanism, and are corresponded with two object lens.The doublet of the present invention
Synchronous focusing device has the following advantages：
（1）Easy to operate, man-machine efficacy is good.Two object lens can synchronous-focusing, it is quick and easy；
（2）It is simple in structure, dependable performance.Simple structure, it is ensured that reliable performance.Two detectors are commonly mounted on tune
On focusing mechanism, synchronous to retreat, scientific in principle is simple in structure, and fit clearance designs in addition, ensures mechanism accuracy, reliability；
（3）Mechanism is ingenious, mitigates weight.Using two objective tubes as focusing axis, any auxiliary structure parts are not increased, as possible
Combinatorial construction part not only simplifies mechanism, and alleviates product weight.
Description of the drawings
Fig. 1 is doublet synchronous focusing device structural schematic diagram provided by the invention.
Specific implementation mode
It is further to a kind of doublet synchronous focusing device work proposed by the present invention below in conjunction with the drawings and specific embodiments
It is described in detail.According to following explanation and claims, advantages and features of the invention will become apparent from.It should be noted that attached drawing
It is all made of very simplified form and uses non-accurate ratio, only to convenient, lucidly the aid illustration present invention is implemented
The purpose of example.
Embodiment one
The present embodiment one provides a kind of doublet synchronous focusing device, as shown in Figure 1.The doublet synchronous focusing device packet
Include 1, two detector of focus adjusting mechanism and two object lens.It is visited specifically, two detectors are respectively the first detector 21 and second
Device 22 is surveyed, two object lens are respectively the first object lens 31 and the second object lens 31.The focus adjusting mechanism 1 is opened there are two pilot hole, and
The focus adjusting mechanism 1 does the processing of aluminum or aluminum alloy hard anodizing and the gap design that is slidably matched.Described two object lens installations
Both sides in 1 the same end of the focus adjusting mechanism, as the focusing axis of the focus adjusting mechanism 1, and described two detectors are simultaneously
Any position of 20 meters of the detection to infinity.First detector 21 and second detector 22 are mounted on the focusing machine
On the corresponding position of structure 1, and first detector 21 is corresponding with first object lens 31, second detector 22 and institute
State the second object lens 32 correspondence.The focus adjusting mechanism 1 drives first detector 21 synchronous with second detector 22 front and back
It is mobile, ensure the consistency of the optical axis in focussing process.
Foregoing description is only the description to present pre-ferred embodiments, not to any restriction of the scope of the invention, this hair
Any change, the modification that the those of ordinary skill in bright field does according to the disclosure above content, belong to the protection of claims
Range.
