WebWhen alone, positive primary and secondary spherical aberration induce small hyperopic shifts in refraction, but in the presence of other higher order aberrations, secondary spherical aberration can induce significant myopic shifts in refractive error, as predicted by the combined lower order r(4) & r(2) component of Z60. WebAug 30, 2024 · If it has a smooth surface (much easier to make on a spherical mirror than on a parabolic one), the performance can be extremely good. A 6" f/8 spherical primary with a smooth figure is much preferable to a parabolic one with a rough surface, because the rough surface will scatter a lot of light and have poor contrast.
