Abstract: PROBLEM TO BE SOLVED: To constitute a high-performance optical system of a small number of lenses by allowing medium to have specified refractive index distribution and making both surfaces thereof specified diffraction optical surfaces. SOLUTION: The medium has the refractive index distribution expressed by an expression I and both surfaces thereof are the diffraction optical surfaces expressed by an expression II. In the expression I, H means height in a direction perpendicular to an optical axis, N0 means a refractive index on the optical axis, N1 means a quadratic refractive index distribution coefficient, N2 means a forth-order refractive index distribution coefficient, N3 means a sixth-order refractive index distribution coefficient and N4 means an eighth-order refractive index distribution coefficient. In the expression II, ϕ(H) means a phase function, H means height in the direction perpendicular to the optical axis, Ri is the i-order phase function and λ0 means design wavelength.  Thus, the direction of the dispersion distribution of a refractive index distribution type lens becomes a direction where production is facilitated.
