Abstract: PURPOSE:To obtain a Fresnel lens which has a large numerical aperture and high convergence efficiency and is relatively easily machined by determining the height and wedge angle of each ring so that a light phase on an optional point of the ring is close to zero as much as possible. CONSTITUTION:The phase of light reaching a focus from an optional point of each ring 5 is made to approximate to zero as much as possible by not a curved surface, but a wedge surface, thereby obtaining an ideal Fresnel lens. The parabolic light phase 6 of a circular aperture is approximated by a straight line (g), and a straight line is added having the opposite sign from said straight light (g); and phase terms in this section r1 and r2 are as shown by a curved line 8 and almost zero except a few remaining terms. For the purpose, the width (c) of each ring 5 is set to the same width, the height of the ring 5 paral lel to the optical-axis direction of its internal diameter is so determined that the light phase on the internal diameter circumference is close to zero as much as possible, and the wedge angle of each ring 5 is so determined that the light phase at the optional point on the ring 5 is closed to zero as much as possible. Consequently, even when the number of rings is decreased, a convergence diame ter is reduced and convergence efficiency is improved.
