System.Wherein the first lens and the 3rd lens all have positive refracting power, can balance optical camera chain refracting power distribution, and be advantageous to
Reduce the susceptibility of photo-optic system.In addition, the 5th lens image side surface is concave surface at dipped beam axle, flexion is helped avoid
Power concentrations in the 5th lens, and reduce lens perimeter because curvature is excessive and so that lens are excessively bent, and then reduce shaping
The problem of bad.Furthermore the 6th lens image side surface is concave surface at dipped beam axle, and the 6th lens image side surface is located to be convex in off-axis
Face, the principal point for helping to make photo-optic system effectively shortens the total length of photo-optic system away from image side end, with profit
In the miniaturization of photo-optic system, further can modified off-axis aberration to lift periphery image quality.When meeting specified conditions
When, contribute to the refracting power balanced arrangement for making the first lens and the 3rd lens, can effectively reduce the generation of aberration.So this hair
Bright photo-optic system can have the characteristic of large aperture, good optical aberration correcting and miniaturization concurrently simultaneously.
Although the present invention is disclosed above with embodiment, so it is not limited to the present invention, any to be familiar with this skill
Person, without departing from the spirit and scope of the present invention, when can be used for a variety of modifications and variations, therefore protection scope of the present invention is worked as
It is defined depending on the scope of which is defined in the appended claims.
