In the present invention, entrance pupil group overall light focal power is negative, emergent pupil group overall light focal power is just, and to spherical aberration, coma, aberration, the rectification of the senior amount of aberration all has exclusive lens combination and diaphragm to realize, which improve the adaptive faculty of camera lens to different temperatures environment, at different temperatures, the effect of expanding with heat and contract with cold of each eyeglass is similar to, but correct due to light path and realize by exclusive lens combination and diaphragm, each eyeglass after expanding with heat and contract with cold still can be mated mutually to the correcting function of optical transmission process, can not Yin Wendu change and affect camera lens to spherical aberration, coma, aberration, the rectification of CRA, camera lens still can normally work under high temperature or low temperature environment.
Light path of the present invention adopts multiple eyeglass, the focal power reasonable distribution of each eyeglass in light path, and has the cemented doublet structure being specifically designed to color difference eliminating, and this makes camera lens reasonably be corrected at the aberration of the wavelength coverage of 480 ~ 850nm and balance.Make camera lens can not only blur-free imaging under photoenvironment in the daytime, under night pole low-light (level) environment, by infrared light filling, also can blur-free imaging.
In the present invention, the cemented doublet structure for correcting dispersion being set in emergent pupil group, the harmony of the incident angle size of front and back arrangement of mirrors sheet can be ensured in light path on the whole, thus reduce camera lens susceptibility, reduce camera lens cost, be convenient to produce.Guarantee in different operating light wave band, the focal power of entrance pupil group and emergent pupil group still keeps reverse, to improve the popularity of camera lens application scenario simultaneously.
From the size characteristic of lens each in scheme of the present invention, the lens wearer R value that the present invention adopts is moderate, while alleviating eyeglass assembly difficulty, also reduces processing cost, and contributes to the optical sensitive degree reducing camera lens.
In the present invention, optical filter is positioned in the light exit direction of emergent pupil group, is namely positioned at optical line terminal, because this camera lens leads to greatly light quantity camera lens, clear field is comparatively large, arranges optical filter at optical line terminal, contribute to filtration variegated, eliminate polarisation (veiling glare of reflection), thus promote image quality further.
In the present invention, the light path relative aperture F=1.4 that entrance pupil group, diaphragm and emergent pupil group are formed
,have larger logical light quantity, make camera lens light-inletting quantity sufficient, can in the more dim lower use of environment.
In the present invention, light path overall length ∑≤22mm that described entrance pupil group, diaphragm and emergent pupil group are formed, optics rear cut-off distance L ' >=6mm.Light path overall length is shorter, contributes to the miniaturization of lens design.
