A biconvex lens is a positive lens characterized by a longer focal length in the middle and shorter focal lengths at both ends.
These lenses are used in a wide variety of applications such as camera lenses, projectors, telescopes and microscopes.
Bi-convex lenses are often used to expand light beams.
In this article, we discuss the properties, functions, and applications of biconvex lenses for beam expansion.
Bi-convex lenses are made of optical glass and are convex on both sides.
The center of the lens is thicker than the edges, which provides a focal point for the light rays entering the lens.
Light rays entering the lens are refracted and converged to the focal point.
The distance between the focal point and the center of the lens is the focal length.
The focal length of a biconvex lens depends on the curvature of the lens and the refractive index of the glass.
