Embodiment 1
[0106] Table 1 shows the lens data and various data of the imaging lens according to Example 1. In the lens data in Table 1, the surface number indicates the i-th (i=1, 2, 3, ...) surface that increases sequentially toward the image side, taking the surface of the component closest to the object side as the first surface No. In addition, the lens data of Table 1 also includes the addition of the aperture stop St and the optical part PP.
[0107] Ri in Table 1 represents the radius of curvature of the i-th (i=1, 2, 3, ...) surface, and Di represents the light of the i-th (i=1, 2, 3, ...) surface and the i+1 surface Face spacing on axis Z. In addition, Ndj represents the refractive index with respect to the d-line of the j-th (i=1, 2, 3, . Indicates the Abbe number of the j-th optical element with respect to the d-line. In Table 1, the unit of the radius of curvature and surface interval is mm, and the radius of curvature is positive when the object is convex sideways, and n...
Embodiment 2
[0115] The lens data and various data of the imaging lens related to Example 2 are shown in Table 2, and the lens configuration diagram is shown in Figure 7 . exist Figure 7 , symbols Ri and Di correspond to Ri and Di in Table 2. In addition, Table 2 and Figure 7 The configuration example of the second embodiment shown does not include the optical component PP, but the lens system of the second embodiment may be used by inserting an optical component between the lens system and the imaging surface as in other embodiments.
