Geometrical Optics is an important scientific area of training of the undergraduate
science students. It is usually restricted in lenses and mirrors of relatively small lens
aperture in which the various errors are considered to be negligible. Our intent in this
publication is the experimental approach and study of the spherical aberration of the
non-ideal concave mirror with a large aperture, in which the spherical aberration is
not negligible. The focal length and the radius of curvature of the mirror are also
determined. The same experimental setup can be used to determine the focal length of
ideal concave mirrors with negligible errors for an introductory level of geometrical optics.
