Abstract
The utility model relates to an adjustable bright reticule low light night sight. It is characterized in that a light splitting refracting/reflecting mirror for reticule lighting is provided on the main optical between the image enhancer fluorescent screen and the eyepiece of the low light night sight, a reticule board and an adjustable bright reticule lighting circuit on the corresponding position on one side of the light splitting refracting/reflecting mirror. Said sight can adjust the brightness of the reticule board continuously to meet sighting needs for different environments, and make reticule and fluorescent screen coincide with the focal plane of the eyepiece by adjusting and calibrating the axial distance of the reticule board, eliminating the problem of misalignment between the reticule surface and the image surface effectively, eliminating sight parallax and realizing precise sighting.
Description
Technical field
The utility model belongs to the optical instrument technical field, is that a kind of adjustable showing the score drawn the lll night vision gun sight.
Background technology
Used lll night vision gun sight adopts the refraction type object lens usually at present, and the graduation system in the mirror adopts graticule and image intensifier video screen sticking-type structure, is to realize the sighting at night function with dark graduation form.The problem that this graduation system exists is: the one, there is certain clearance between dividing plane and image planes, and cause not overlapping of dividing plane and image planes, in use easily produce and aim at parallax; The 2nd, the graduation groove is to rely on the image intensifier video screen to throw light on, and when using under environment with dark light, often because of the graduation groove does not see, and can't accurately aim at.
The utility model content
The purpose of this utility model provides and a kind ofly can solve not COINCIDENCE PROBLEMS of dividing plane and image planes, eliminate parallax, and adjustable the showing the score that can accurately aim under various environment is drawn a lll night vision gun sight.
Realize that the technical scheme that the purpose of this utility model is taked is: on the video screen and the main optical path between the eyepiece of the image intensifier of lll night vision gun sight, be provided with the beam split catadioptric mirror that is used for the graduation illumination path, in the corresponding position of beam split catadioptric mirror one side, be respectively arranged with a graticule and the adjustable stroke lighting circuit of showing the score.
Described beam split catadioptric mirror adopts the Amici prism structure of gummed up and down, and is coated with on the cemented surface of Amici prism and is coated with beam splitting coating.
Described graticule is installed in the seat ring, and the groove face on it is corresponding to beam split catadioptric mirror, and seat ring and graticule corresponding side walls are provided with light hole.
The described adjustable stroke lighting circuit of showing the score is to be made of the lighting source, battery, potentiometer and the knob switch that are serially connected on the circuit, and the lighting source on it is corresponding to the light hole on the seat ring, and knob switch is exposed at the corresponding site of mirror body case outward.
Draw a lll night vision gun sight according to adjustable the showing the score that such scheme is made, it is adjustable continuously to realize breaking up plate brightness power, to satisfy the aiming demand of varying environment; And by adjusting and proofread and correct the axial distance of graticule, groove and face on the graticule are overlapped on the focal plane of eyepiece, thereby effectively solved dividing plane and the problem that image planes do not overlap, eliminated the aiming parallax, the purpose that has reached clear observation and accurately aimed at.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Referring to Fig. 1, adjustable showing the score of the present utility model drawn the lll night vision gun sight, form by object lens 1, image intensifier 2, graticule 3, beam split catadioptric mirror 5, eyepiece 7 and the adjustable stroke lighting circuit 4 of showing the score, wherein, beam split catadioptric mirror 5 is arranged on the video screen and the main optical path between the eyepiece 7 of image intensifier 2, and adopts the Amici prism structure of gummed up and down.During making, plate beam splitting coating 6 earlier on the cemented surface with a prism, then with another prism gummed with fluorescence wave band and reflection graduation illumination light wave band.Side at beam split catadioptric mirror 5 is provided with a graticule 3 and the adjustable stroke lighting circuit 4 of showing the score.Graticule 3 is installed in the seat ring 8, groove face on it is provided with light hole 8a corresponding to beam split catadioptric mirror 5 on the sidewall of seat ring 8, this light hole 8a is corresponding to differentiation plate 3, draw the light source that lighting circuit 4 provides by adjustable the showing the score that is provided with, can realize breaking up showing the score of plate 3 and draw function.In this case, the adjustable stroke lighting circuit 4 of showing the score is formed (not shown) by the potentiometer, battery and the knob switch that are contained in the lighting source in the gun sight housing and be serially connected on the circuit, lighting source on it is corresponding to the light hole 8a on the seat ring 8, and knob switch is exposed at the corresponding site of mirror body case outward.By the size of variable resistor resistance in the knob switch regulator potentiometer, can realize the adjustable continuously of lighting source brightness power, to adapt to the graduation brightness request for utilization under the varying environment condition, realize the aiming demand of varying environment.The groove face of graticule 3 is corresponding to beam split catadioptric mirror 5, and lighting source can be realized evenly illumination to the groove face of graticule 3 by the light hole 8a on the seat ring 8.And by proofreading and correct and adjust the axial distance of graticule 3, be zero, groove and face on the graticule 3 are overlapped on the focal plane of eyepiece, reach the purpose of eliminating the aiming parallax, realizing accurate aiming thus until the gap of dividing plane and image planes.
