Technical field
This utility model relates to a kind of night vision device, particularly relates to a kind of intensity adjustable night vision device, belongs to display unit at night technical field.
Background technology
Night vision device is gunsight outside the night that image intensifier is core devices, without infrared searchlight illumination target during its work, and utilize faint light to strengthen, by image intensifier, the visual picture can experienced for human eye according to the reflected light of lower target on fluorescent screen and observe and run-home.Tradition night vision device does not possess brightness control function, when using for a long time at its night vision apparatus as night march or night observation, it is easy to allow user feel visual fatigue, cause ocular pain, thus affecting precision and the persistency of night observation.
Utility model content
In order to solve the weak point existing for above-mentioned technology, this utility model provides a kind of intensity adjustable night vision device.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of intensity adjustable night vision device, and it includes image intensifier, also includes object lens, eyepiece, battery compartment, brightness regulation knob；Object lens are equipped with object lens and regulate device；The right-hand member of object lens is disposed with image intensifier, relay lens system from left to right；Eyepiece is arranged at the right-hand member of relay lens system, eyepiece is equipped with eyepiece and regulates device；
The focal plane of eyepiece is provided with gun sight graticle；The lower end of gun sight graticle is provided with eyepiece handwheel；The lower end of image intensifier and relay lens is provided with helmet conversion equipment；The lower end of helmet conversion equipment is provided with battery compartment；The front side in battery compartment centre position is provided with brightness regulation knob；The left end of battery compartment is provided with on and off switch.Relay lens system is made up of as relay lens, inverted image relay lens, rectification relay lens connecing of being arranged in order from left to right.
The right-hand member of eyepiece is provided with eye-shade；The left end of object lens is provided with lens cap.
Object lens fix each through the fastener of upper end with image intensifier, relay lens system and eyepiece.
This utility model simple in construction, cost is relatively low, and possesses brightness control function, and convenient observation uses and relieving eye fatigue；Additionally, this utility model both can handheld night vision instrument use, it is also possible to use mounted on the helmet or be arranged on weapon as gun sight use, there is wide applicability.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
In figure: 1, object lens；2, object lens regulate device；3, image intensifier；4, relay lens system；5, eyepiece regulates device；6, eye-shade；7, eyepiece；8, battery compartment；9, helmet conversion equipment；10, brightness regulation knob；11, on and off switch.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As it is shown in figure 1, this utility model includes image intensifier 3, it also includes object lens 1, eyepiece 7, battery compartment 8, brightness regulation knob 10；Object lens 1 are equipped with object lens and regulate device 2；The right-hand member of object lens 1 be disposed with from left to right image intensifier 3, relay lens system 4, image intensifier 3 and relay lens system 4 with the use of, faint objective optics image enhaucament, produce the optical imagery of enough brightness for eye-observation；Eyepiece 7 is arranged at the right-hand member of relay lens system 4, eyepiece 7 is equipped with eyepiece and regulates device 5；
The focal plane of eyepiece 7 is provided with gun sight graticle；The lower end of gun sight graticle is provided with eyepiece handwheel；Gun sight graticle there is point of aim mark, gun sight graticle can be made to move up and down by rotating eyepiece handwheel, make the center groove of gun sight graticle to quasi goal；This design had both met soldier's use in night march, it is also possible to is contained on weapon and uses as gun sight；
The lower end of image intensifier 3 and relay lens system 4 is provided with helmet conversion equipment 9, and starting helmet conversion equipment 9 can be converted to helmet-type by this utility model by hand-held, is easily installed on the helmet；
The lower end of helmet conversion equipment 9 is provided with battery compartment 8；The front side in battery compartment 8 centre position is provided with brightness regulation knob 10；Use brightness regulation knob 10 can regulate the intensity of illumination that human eye receives, looking after the too weak meeting of intensity makes people that the resolution of object observing to be reduced, people can be made again uncomfortable or have dizzy sensation too by force, utilize brightness regulation knob 10 can effectively solve the problem that intensity of illumination is too weak or too strong, and avoid receiving same intensity of illumination and producing visual fatigue for a long time；The left end of battery compartment 8 is provided with on and off switch.
Relay lens system 4 is made up of as relay lens, inverted image relay lens, rectification relay lens connecing of being arranged in order from left to right.The right-hand member of eyepiece 7 is provided with eye-shade 6；The left end of object lens 1 is provided with lens cap, and objective lenses can be protected when not in use from scratching and polluting.
Object lens 1 fix each through the fastener of upper end with eyepiece 7 with image intensifier 3, relay lens system 4, and the device after being fixed by fastener has water-proof function.
This utility model simple in construction, cost is relatively low, and possesses brightness control function, conveniently observes use, can also slow down visual fatigue by adjustment brightness when people use for a long time, thus strengthening precision and the persistency of long-time night march or observation；Additionally, this utility model both can handheld night vision instrument use, it is also possible to use mounted on the helmet or be arranged on weapon as gun sight use, there is wide applicability.
Above-mentioned embodiment is not to restriction of the present utility model; this utility model is also not limited to the example above; the change made within the scope of the technical solution of the utility model of those skilled in the art, remodeling, interpolation or replacement, also belong to protection domain of the present utility model.
