Embodiment Construction
[0021] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0022] Such as figure 1 and 2 As shown, a large image surface, high resolution and low distortion optical lens of the present invention, from left to right along the light incident direction, the optical system is composed of four parts: the first lens group 1, the diaphragm 2, the second lens group 3 and the imaging surface 4, wherein the refractive power of the first lens group 1 is positive, and the refractive power of the second lens group 3 is positive.
[0023] The first lens group 1 includes six lenses from left to right along the incident direction of light: biconvex lens one 11, convex-concave lens two 12, biconcave lens three 13, concave-convex len...
