Definitions

  • a discontinuous surface consisting of a ring-shaped refracting surface (4 A, plane) and its side wall surface 5 A is used.
  • the slopes of the two types of lenses 3 0, 3 1 on the small ball portion (near vision portion) 3 2 of lens 29, the concave side and the convex side are almost the same as in Table ⁇ 1 above.
  • the difference is that the second refractive surface of the convex lens and the second lens of the concave lens in Table 1 '1 are different. On the folded surface, it is described as the central part, and it is not in the fc area)! It is only that the continuous surface is used.
