Double Convex lens is a simple lens which comprises two convex surfaces in spherical form, generally having the same kind of radius of curvature. These are also called convex-convex lenses.
Being a kind of simple lens, the biconvex lens has a wide range of applications, but it is not limited to control and focusing of laser beams, quality imaging and also the other kinds of optical instruments.
In a double convex lens or a Plano-convex lens, a collimated or accurately parallel beam of light passes through the lens and converges at a spot or focus coming behind the lens. In such a case, this lens is known as a converging or positive lens. The distance coming from the lens up to the spot is called the focal length of the lens. Since there is a curvature on both sides of the lens, there will be around two focal points and also two centres. The line that is drawn through the middle of the biconvex lens is known as the principal axis.
