WebA fixed focal length lens, also known as a conventional or entocentric lens, is a lens with a fixed angular field of view (AFOV).

AFOV is typically specified as the full angle (in degrees ... WebMar 5, 2024 · It is seen that the aberration is least for a shape factor of about q = − 0.38. The radii of curvatures of the lens must satisfy equation 4.2.7 as well as q = − 0.38. so that, for f = 20 cm and q = −0.38, the radii of curvature for least spherical aberration should be r 1 = 17.4 cm and r 2 = −38.7 cm.
