Longitudinal spherical aberration
WebThe new Summilux-M 50 f/1.4 ASPH. is available in the silver or black anodized version. The focal length classic is suited for all current and for all future M cameras. In combination with the Leica M-Adapter L, this new lens also enables photographing and filming with the Leica SL2 and the SL2-S.

Web20 de abr. de 2012 · Accepted Answer. The following code lets you simulate the PSF associated with spherical aberration (as well as diffraction). You need to specify the PSF sampling pitch, the wavelength, the aperture diameter, the system focal length, the amount of spherical aberration, and the PSF array size. WebSpherical aberration occurs because marginal rays are deviated more than the paraxial rays. Therefore, if we can reduce the deviation, we decrease the aberration. If we look …
