Spherical aberration is most pronounced when the diaphragm of the lens is wide open (maximum aperture). Stopping down the lens even by a single stop dramatically reduces spherical aberration, because aperture blades block the outer edges of spherical lenses. A clear example of this can be found ...
Chromatic aberration, also known as “color fringing” or “purple fringing”, is a common optical problem that occurs when a lens is either unable to bring all wavelengths of color to the same focal plane, and/or when wavelengths of color are focused at different positions in the focal plan...
What is a radial magnetic field? What is chromatic aberration? What is preserved lordosis? What is internal refraction? What is the active recovery zone? What is physical limnology? What is the momentum of a parked car? What is spherical bacterium?
A combination of two thin convex lenses of focal length 0.3 m and 0.1 m will have minimum spherical and chromatic aberrations if the distance between them is : View Solution A combination of two thin convex lenses of focal length 0.3 m and 0.1 m will have minimum spherical and chromatic abe...
Where is plano convex lens used? Plano-Convex lenses are the best choice forfocusing parallel rays of light to a single point. They can be used to focus, collect and collimate light. The asymmetry of these lenses minimizes spherical aberration in situations where the object and image are locat...
Aberrations such as axial chromatic aberration, spherical aberration, coma, astigmatism, and field curvature introduce blur. Aberrations such as distortion, coma, and lateral chromatic aberration induce warping. Aberration control is important in the design of AR HMD optics. An example all-reflective ...

Spherochromatism is spherical aberration. If you design the scope for best performance in green, then the blue and the red will both have spherical aberration. This is not the same as the defocus from chromatic aberration.With CA, each color has a precise best focus. With Spherochromatism, ...
* 9mm is sharp and contrasty, almost as good as a nice 9mm Fujiyama ortho I compared it to * Both have finicky eye placement and spherical aberration of the exit pupil (kidney beaning) * Both are much more comfortable and immersive than Plossls, but optically are not any better ...
