Unlike conventional spherical or flat mirrors, a cylindrical mirror's reflective surface is part of a cylinder. In the direction of curvature, it can focus or diverge light, similar to a spherical mirror. In the curvature-free direction, it acts like a flat mirror, altering the light's path without changing its divergence or convergence. This unique property enables cylindrical mirrors to transform a input beam into a one-dimensional line or to focus/collimate a line source into a point.
