Disclosed herein optical imaging lens set can include an aperture.It is arranged at an object and aperture
Between the lensed focal length of institute be ff, the lensed focal length of institute being arranged between aperture and imaging surface is fr, its
Following condition can be met：0<ff/fr<1.25.Thereby, lens group flexion that can be before appropriate balance aperture
After power and aperture lens group refracting power distribution, make optical imaging lens set have concurrently large aperture with it is small
The characteristic of type.When only single element lens are arranged between object and aperture, ff is to be equal to this lens
Focal length；When there is multi-disc lens to be arranged between object and aperture, ff is the conjunction for being equal to these lens
Coking away from.Similarly, when only single element lens are arranged between aperture and imaging surface, fr is to be equal to this
The focal length of lens；When there is multi-disc lens to be arranged between aperture and imaging surface, fr is to be equal to these lens
Synthesis focal length.
3rd lens, the 4th lens, the 5th lens and in the 6th lens all lens surfaces maximum effectively half
The average value in footpath is SDavg, and the aperture radius of aperture are SDstop, and it can meet following condition：0.5<
SDavg/SDstop<1.25.Thereby, it can be ensured that periphery light-inletting quantity is sufficient.Foregoing all lens surfaces are most
The average value of big effective radius refers to the arithmetic average of these maximum effective radiuses.
The radius of curvature of the second lens image side surface is R4, and the focal length of optical imaging lens set is f, and it can
Meet following condition：0.50<R4/f<4.5.Thereby, be conducive to correcting the aberration produced by the first lens.
