Concave Mirror

Concave Mirror Description

Plano concave mirror are used for focusing, collecting, and imaging with no chromatic aberration. They are suitable for a variety of applications, from laser beam manipulation to instrument construction and quality imaging. The longer focal lengths are especially convenient for such tasks as laser beam collimating.

The concave mirror has a reflection surface that curves inward, resembling a portion of the interior of a sphere. When light rays that are parallel to the principal or optical axis reflect from the surface of a concave mirror, they converge on the focal point (black dot) in front of the mirror. The distance from the reflecting surface to the focal point is known as the mirror’s focal length. The size of the image depends upon the distance of the object from the mirror and its position with respect to the mirror surface.
