Spherical type

Web12. sep 2024 · We can define two general types of spherical mirrors. If the reflecting surface is the outer side of the sphere, the mirror is called a convex mirror. If the inside surface is the reflecting surface, it is called a concave mirror. Symmetry is one of the major hallmarks of many optical devices, including mirrors and lenses. WebSpherical bearings are self aligning bearings used extensively on the driven parts in the aerospace, automobiles, railways and industrial machines.
