Embodiment Construction
[0093] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0094] Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same numerals.
[0095] The term "a lens has positive refractive power (or negative refractive power)" in this specification means that the lens has positive refractive power (or negative refractive power) in the area near the optical axis. "The object side (or image side) of a lens has a convex surface (or concave surface) located in a certain area" means that the area is closer to the direction parallel to the optical axis than the area immediately outside the area in the radial direction. "Outwardly convex" (or "inwardly concave"), with figure 1 For example, where I is the optical axis and the lens is radially symmetrical to each other with the optical axis I as the axis of symmetry, the object si...
