Abstract
The utility model discloses a high definition camera lens suitable for a large temperature difference. The camera lens comprises a spherical lens group of a glass material and an aspheric lens group of a plastic material. The aspheric lens group comprises an even number of aspheric lenses. A quantity of the aspheric lenses with a positive focal length contained by the aspheric lens group is equal to a quantity of the aspheric lenses with a negative focal length. Through the above structure, a resolution ratio and a pixel of the camera lens are high; and when an ambient temperature is changed, focal length changes generated by the aspheric lenses with the positive focal length and the aspheric lenses with the negative focal length which have the same quantity because of the temperature can be mutually compensated so that the camera lens can be used in a wide temperature scope; an usage effect is not influenced. A product quality is increased and competitiveness of a market is increased too.
Description
Technical field
The utility model relates to a kind of high definition camera lens, particularly the applicable high definition camera lens of a kind of large temperature difference.
Background technology
High definition camera lens is stricter to the temperature requirement of environment for use now.It is good that a lot of camera lenses are separated picture in season in spring and autumn, arrived winter and summer picture element with regard to variation.Some camera lens picture element in winter is good, and summer is poor.Also some camera lens picture element in summer is good, and winter is poor.Because be difficult to, in a larger temperature range, guarantee that picture element is constant when optical design.So it is good that people for actual needs, control emphatically camera lens picture element in a bit of temperature range.The camera lens of outdoor application northeastward for example, can be designed to when temperature is lower picture element better because in the north 1 year a very long time all colder, the time of heat is not long.And in Guangdong etc. 1 year a very long time very hot place all, camera lens can be designed to preferentially guarantee separate and look like when temperature is high.Seldom there is camera lens can take into account a very wide temperature range, this is because along with temperature variation, the performance of lens materials also more variation, cause camera lens picture element variation, above-mentioned reason is mainly to have used in camera lens odd number sheet plastic aspherical element eyeglass, plastics are more responsive to temperature variation, its refractive index can the significant change with temperature, thereby causes its focal length variations, thereby when all plastic aspherical element eyeglasses one change, the variation of its generation can not be complementary, thereby cause the problem that picture element is low.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of large temperature difference applicable high definition camera lens.
The utility model solves the technical scheme that its technical matters adopts:
The high definition camera lens that a kind of large temperature difference is applicable, it is characterized in that: comprise the spheric glass group of glass material and the aspherical lens group of plastic material, the aspherical lens that described aspherical lens group comprises is even number sheet, and the aspherical lens of positive focal length and the aspherical lens quantity of negative focal length that aspherical lens group comprises equate.
This camera lens spheric glass group and aspherical lens group put in order for, the first spheric glass, the first aspherical lens, the second spheric glass, the 3rd spheric glass, the 4th spheric glass, can form with the first aspherical lens the second aspherical lens of mutual compensation effect.
The aspherical lens that described the first aspherical lens is negative focal length, the aspherical lens that described the second aspherical lens is positive focal length.
The focal length value of described the first aspherical lens and the second aspherical lens is close.
Described the first aspherical lens is identical with the focal length value of the second aspherical lens.
Described the second spheric glass, the 3rd spheric glass, the 4th spheric glass combine by two spheric glasses.
The beneficial effects of the utility model are: this camera lens comprises the spheric glass group of glass material and the aspherical lens group of plastic material, the aspherical lens comprising described in described aspherical lens group is even number sheet, and the aspherical lens of the positive focal length that aspherical lens group comprises equates with the aspherical lens quantity of negative focal length, pass through said structure, not only resolution and the pixel of this camera lens are higher, and when environment temperature changes, the aspherical lens Yin Wendu of the aspherical lens of the positive focal length of equal number and negative focal length and the focal length variations that produces can compensate mutually, thereby this camera lens can be used in very wide temperature range, and do not affect result of use, not only improved the quality of product, and strengthened the competitive power in market.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, the utility model discloses the applicable high definition camera lens of a kind of large temperature difference, comprise the spheric glass group of glass material and the aspherical lens group of plastic material, the aspherical lens that described aspherical lens group comprises is even number sheet, and the aspherical lens of positive focal length and the aspherical lens quantity of negative focal length that aspherical lens group comprises equate.
In Yu Ben specific embodiment mechanism, this camera lens spheric glass group and aspherical lens group arranged in co-axial alignment and its put in order into, the first spheric glass 1, the first aspherical lens 2, the second spheric glass 3, the 3rd spheric glass 4, the 4th spheric glass 5, can form with the first aspherical lens 2 the second aspherical lens 6 of mutual compensation effect, the first spheric glass 1 is concavees lens, the second spheric glass 3 is concavees lens, the 3rd spheric glass 4 and the 4th spheric glass 5 are convex lens, the first aspherical lens 2 is concavees lens, the second aspherical lens 6 is convex lens, and the aspherical lens that the first aspherical lens 2 is negative focal length, the aspherical lens that described the second aspherical lens 6 is positive focal length, certainly an above-mentioned just instantiation of this patent, the first aspherical lens 2 also can be the aspherical lens of positive focal length, described the second aspherical lens 6 also can be the aspherical lens of negative focal length, in order to reach complementary effect, the focal length value of the first aspherical lens 2 and the second aspherical lens 6 is close, best situation is, the first aspherical lens 2 is identical with the focal length value of the second aspherical lens 6.
As a kind of variation structure of this patent, the second spheric glass 3, the 3rd spheric glass 4, the 4th spheric glass 5 combine by two spheric glasses, and the mode of combination can, for the mechanical one that fixedly fits into, also can be bonded as one by glue.
The applicable high definition camera lens of a kind of large temperature difference above the utility model embodiment being provided, be described in detail, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
