Spherical Aberration Correction Using Refractive-Diffractive Lenses with an Analytic-Numerical Method
spherical aberration flat or curved phase coefficients
2011/4/21
We propose an alternative method to design diffractive lenses free of spherical aberration for monochromatic light. Our method allows us to design diffractive lenses with the diffraction structure rec...
