The invention discloses a kind of optical sights, including object lens gluing, field lens, deviation mirror, eyepiece gluing and the eyepiece monolithic set gradually, deviation mirror includes the ZF1 glass of close field lens side and the H-K9L glass of other one side, the focal length of field lens is 47.089-50.089mm, the focal length of deviation mirror is 35.846-39.846mm, and the focal length of eyepiece gluing is at 1170.244-1174.244mm.The invention has the benefit that distance of exit pupil becomes 4 inches by original 3 inches；Visual field becomes 20 degree by original 17 degree；Resolution ratio is by original 8 " becoming 4 " -5 "；System overall length becomes 300 ± 1mm by original 310mm.
Description
Technical field
The present invention relates to a kind of optical systems, more particularly to a kind of optical sight.
Background technique
The main function of optical sight is imaged using optical lens, target image and sight line is overlapped same
On a focussing plane, aiming point will not be influenced eyes are slightly offset.Usual optical sight can with magnified image multiple,
Also there is not amplification factor optical sight.And the gun sight of amplifying factors can be divided to fixed multiple or adjustable multiple two classes,
If 4x28 refers to 28 millimeters of objective lens diameter, the gun sight of fixed 4 times of enlargement ratio, 3-9x40 is then 40 millimeters of object lens, adjustable
Gun sight of the whole enlargement ratio from 3 times to 9 times.In the prior art, optical sight is there is also defect, such as distance of exit pupil, depending on
, resolution ratio is all relatively low.And system overall length is also relatively long.
Summary of the invention
The present invention provides a kind of optical sight, solves the problems, such as above-mentioned.
The present invention is realized by following technical solution:
A kind of optical sight, including the object lens gluing that sets gradually, field lens, deviation mirror, eyepiece be glued and eyepiece monolithic,
It is characterized in that, the deviation mirror includes the ZF1 glass of close field lens side and the H-K9L glass of other one side, the field
The focal length of mirror is 47.089-50.089mm, and the focal length of two pieces of deviation mirrors is 35.846-39.846mm, and the eyepiece is glued
Focal length at 1170.244-1174.244mm.
Above-mentioned a kind of optical sight, which is characterized in that the object lens gluing includes the 2nd H-K9L glass and F4 glass
Stack combinations, the eyepiece gluing include ZF2 glass and the 3rd H-K9L glass stack combinations.
Above-mentioned a kind of optical sight, which is characterized in that the focal length of the field lens is 49.089mm, two pieces of steerings
The focal length of mirror is 37.846mm, and the focal length of the eyepiece gluing is at 1172.244mm.
Above-mentioned a kind of optical sight, which is characterized in that the material of the field lens is H-ZK3 glass.
Above-mentioned a kind of optical sight, which is characterized in that the material of the eyepiece monolithic is K9L glass.
The invention has the benefit that distance of exit pupil becomes 4 inches by original 3 inches；Visual field is by 17 degree of original changes
At 20 degree；Resolution ratio is by original 8 " becoming 4 " -5 "；System overall length becomes 300 ± 1mm by original 310mm.
