Abstract
The utility model relates to an optical instrument and specifically to a night vision device. A technical scheme of the night vision device equipped with a back-turning lens is that the night vision device comprises an object lens (2), an image intensifier (10), an ocular lens (11), a power switch (4), and a battery cylinder (3); the object lens (2) employs the back-turning lens to converge an optical path to the cathode surface of the image intensifier (10); the image intensifier (10) intensifies an optical image and converts the optical image into a clear object for human eye observation; a battery for supplying power to the image intensifier (10) is installed in the battery cylinder (3); the power switch (4) is used for adjusting the on-off state of the power; and the ocular lens (11) magnifies an image displayed on the screen of the image intensifier (10) for human eye observation. The night vision device has advantages of long observation distance, good lightness, and easy use.
Description
Technical field
The utility model relates to a kind of optical instrument, is specifically related to a kind of night vision device.
Background technology
Current night vision device is on the market all common optical lens, and the multiplying power of camera lens has 1 times, 3 times, 5 times three kinds, 500 meters, optimum visual observing effect vehicle, and 300 meters of personnel, cannot meet remote observation and use.
Summary of the invention
The purpose of this utility model is: to make up above the deficiencies in the prior art, provide a kind of night vision device that reflex lens is installed;
The technical solution of the utility model is: the night vision device of reflex lens is installed, and it comprises: object lens, image intensifier, eyepiece, switching knob and battery sleeve;
Object lens adopt reflex lens, reflex lens adds the little concave mirror that is contained in lens center by a slice center concave mirror with holes and a slice on the basis of common lens, the light reflecting into by camera lens front lens, through two secondary reflections, is made light path be converted into three sections and gathered to the cathode plane of image intensifier;
Image intensifier adopts super three-generation image enhancer, and image intensifier strengthens optical imagery and be converted to the clear scenery of confession eye-observation; The focusing handwheel being arranged on image intensifier by adjusting is realized focusing; The shank of image intensifier is provided with battery sleeve and switching knob, the in-built battery that power supply is provided to image intensifier that is useful on of battery sleeve, and switching knob is for adjusting the on off operating mode of power supply;
Eyepiece amplifies the image being presented on image intensifier screen for human eye observation, by regulating the diopter adjustment handwheel on eyepiece to realize dioptric adjustment;
The shank two ends of image intensifier connect respectively object lens, eyepiece; Object lens connect light shield.
The beneficial effects of the utility model are: (1) the utlity model has the advantages such as viewing distance is far away, light and handy, easy to use, can and carry out low-light camera with CCD, video camera, the first-class equipment connection of digital vedio recording, also can be connected with monitor and show that image supplies many people to watch;
(2) adopt super three-generation image enhancer faint two-dimensional space optical imagery can be converted to the digital video signal of one dimension, and be reproduced as the image that is applicable to eye-observation;
(3) object lens adopt reflex lens, while making light by the first arrangement of mirrors sheet, are not direct imagings, but just imaging after two secondary reflections; Reflex lens length can shorten, and has dwindled to greatest extent volume, the weight of night vision goggles, and camera lens replaces having the plane of refraction of dispersion with dispersionless reflecting surface, and dispersion is controlled good;
(4) for preventing that light that video screen sends from penetrating by eyepiece, by the other side, found that spy is provided with eyeshade, when eye socket contacts eyeshade with certain pressure, its blade opens automatically to observe, and eye socket leaves rear blade in closure state.
