Avantier Inc.
Spherical Mirrors Types of Spherical Mirrors. Concave Spherical Mirrors: These mirrors curve inward and have a reflective surface that can focus light. They have a positive focal length and a positive radius of curvature. Concave mirrors magnify objects that are close to them. Convex Spherical Mirrors: These mirrors curve outward and typically make objects appear smaller than they are. They have a negative focal length and a negative radius of curvature. Convex mirrors are often used to expand the field of view... (read more)Browse Optical Mirrors Datasheets for Avantier Inc. -
