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 in the focus shift article.
Centerless grinders have been making precision parts for more than 115 years, and many of the machines are so durable that 40- and 50-year-old machines are still grinding away in shops across the US. Older machines, with strong, cast-iron frames and beds, are often rebuilt with new features. Yet turnkey automated centerless technology is producing […]
