. . . "When the optical axis is the X axis, an axis perpendicular to the optical axis is the H axis, the direction in which light travels is the positive direction, r is a paraxial radius of curvature and B, C, D, and E are aspherical coefficients, the shape of the aspherical surface is expressed as follows:X=H2/r1+(1-(H/r)2)1/2+B??H4+C??H6+D??H8+E??H10 In the second and third numerical examples, the las" .
