L6-32. Optical Board - Spherical Aberration In Lens
Purpose
To demonstrate spherical aberration using rays.
Equipment
Optical board with slit baffle, concave and convex lenses to produce parallel rays, and spherical convex lens for aberrations.
Images
Description
A beam of parallel rays is focused by a convex spherical lens. If the entire lens is used, considerable spherical aberration results. Reducing the aperture (equivalent to reducing the f-number of a lens) by sliding the slit baffle away from the source reduces the spherical aberration.
