Detailed description of the invention
In order to solve optics tight shot of the prior art cannot meet big image planes large aperture problem, this Invention provides a kind of optics tight shot, and this optics tight shot is arranged in order from the object side to image side and includes: First battery of lens, the second battery of lens, diaphragm and the 3rd battery of lens;Wherein, the focal power of the first battery of lens Being negative, the focal power of the second battery of lens is just, the focal power of the 3rd battery of lens is just, it is saturating that diaphragm is positioned at second Between mirror group and the 3rd battery of lens, wherein, the first battery of lens includes: the biconvex first that focal power is positive is saturating Mirror, focal power be negative double concave type the second lens, focal power be that negative double concave type the 3rd lens, focal power are Positive biconvex the 4th lens.
Below in conjunction with the accompanying drawings the preferred embodiment of the present invention is described in detail.
Refering to shown in Fig. 1, for the structural representation of optics tight shot a kind of in the present invention.
The direction being previously mentioned in following example for, such as: upper and lower, left and right, front or rear etc., only It it is the direction with reference to accompanying drawing.Therefore, the direction term of use is used to explanation, rather than is used for limiting the present invention.
A kind of optics tight shot, is arranged in order from the object side to image side and includes: the first battery of lens A, second Battery of lens B, diaphragm ST and the 3rd battery of lens C.
Wherein, the focal power of the first battery of lens A is negative, and the focal power of the second battery of lens B is just, the 3rd The focal power of battery of lens C is just, diaphragm ST between the second battery of lens B and the 3rd battery of lens C, its In, the first battery of lens A includes: focal power be positive biconvex the first lens 1, focal power be negative concave-concave Type the second lens 2, focal power are that the biconvex the 4th that negative double concave type the 3rd lens 3, focal power are positive is saturating Mirror 4.
As long as the first battery of lens meets focal power here is to bear and meet above-mentioned constituent relation effectively to protect The demand of card high definition imaging, and contribute to expanding the image planes of optics tight shot and visual field and improving optics The resolution of tight shot.
Optionally, the second battery of lens B includes: focal power is that positive biconvex the 5th lens 5, focal power are Negative double concave type the 6th lens 6, focal power is positive biconvex the 7th lens 7.
3rd battery of lens C includes: focal power is for just, and concave surface is towards concave-convex type the 8th lens 8 of thing side, light Focal power be negative double concave type the 9th lens 9, focal power be that positive biconvex the tenth lens 10, focal power are for just Biconvex the 11st lens 11, focal power be negative double concave type the 12nd lens 12, focal power be positive Biconvex the 13rd lens 13.
Here the first battery of lens A, the second battery of lens B, diaphragm ST and the 3rd battery of lens C constitutes anti- Long distance structure.
It is adapted to realize big image planes and the specification requirement of big visual field it is true that anti-long distance version compares. And the present invention is exactly based on negative rear positive anti-long distance version before have employed in focal power distribution, Yi Jihe The eyeglass face type of reason and minute surface selection, reasonable while meeting specification demands achieve aberration control System.
Each lens in first battery of lens A, the second battery of lens B, the 3rd battery of lens C are spherical lens. Owing to spherical lens has relatively low cost, the manufacturing cost of the tight shot of the present embodiment therefore can be reduced. Additionally, use spherical lens can also reduce manufacturing tolerance sensitivity and the difficulty of inspection material, be conducive to big Amount produces.
In the present embodiment, for reducing aberration, reduce lens surface reflection quantity, in the first battery of lens A, First lens 1 and the second lens 2 gluing form first group of cemented doublet, the 3rd lens 3 and the 4th lens 4 gluings form second group of cemented doublet.
In the second battery of lens B, the 6th lens 6 and the 7th lens 7 gluing form the 3rd group of cemented doublet.
In the 3rd battery of lens C, the 8th lens the 8, the 9th lens 9 and the tenth lens 10 gluing form three Balsaming lens, the 12nd lens the 12 and the 13rd lens 13 gluing forms the 4th group of cemented doublet.
It may be noted that the present invention is not limited with above-mentioned gluing.Glued scheme herein is mainly from assembling just The preferred version proposed from the standpoint of the raising of prompt, transmitance etc..Usually, glued scheme makes contiguity into Scheme is also feasible.
In the present embodiment, between the second battery of lens B and the 3rd battery of lens C, aperture light is preferably configured Door screen ST.By so configured, before and after making diaphragm ST, positive negative power suitably disperses symmetry, easily carries out all The correction of aberration.If aperture diaphragm ST is arranged in than the second battery of lens B closer to thing side, then emergent pupil Bore becomes big, it has to increasing the bore of the 3rd battery of lens C, lens weight also increases, and is not the most preferred.
Additionally, in the embodiment of the present invention, the effective focal length of the first battery of lens A is effective with optics tight shot Focal length meets the first setting relation, the effective focal length of the second battery of lens B and the effective focal length of optics tight shot Meet second setting relation, first set relation as: 0.8 < | F1/Feff| < 2.2, second set relation as: 0.8<F2/Feff< 1.9, wherein FeffFor the effective focal length of optics tight shot, F1It is the effective of the first battery of lens Focal length, F2It it is the effective focal length of the second battery of lens.
Concrete, set relation for first, when | F1/Feff| when exceeding the upper limit, negative power is the most weak, system Length is bigger.When | F1/Feff| when exceeding lower limit, negative power is too strong, and higher order aberratons increases, and distortion is also difficult to Correct.Therefore, the tight shot in the present embodiment meet 0.8 < | F1/Feff| < when 2.2, there is preferably imaging Quality and rational structure space form.
Set relation for second, work as F2/FeffWhen exceeding lower limit 0.8, F2Relatively diminish, i.e. focal power phase Big to becoming, senior coma, astigmatism so can be caused to increase.Work as F2/FeffWhen exceeding the upper limit 1.9, F2Relatively Become big, i.e. focal power diminishes relatively, and optical system so can be caused long, and the 3rd battery of lens bore strengthens, The market requirement to optical system densification cannot be met.
Above-mentioned two imposes a condition, and is mainly reflected in the control to aberration, balance, and to whole optical system The control of system size.By to two controls imposed a condition, improving the performance of optics tight shot.
In the embodiment of the present invention, optics tight shot is image-forming objective lens, and the image planes of optics tight shot are electric charge One in coupled apparatus CCD or CMOS semiconductor sensor CMOS.
