WebThe geometrical shape of the wavefront in case of light diverging from a point source will be diverging spherical wavefront . It can be shown as, (b) Light emerging out of a convex lens when a point source is placed at its focus. When a point source is placed at the focus of a convex lens, the rays emerging from the lens are parallel. WebA lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis.Lenses are made from materials such as glass or plastic and are ground, polished, …

WebGaussian Beam Optics. The Gaussian is a radially symmetrical distribution whose electric field variation is given by the following equation: r is defined as the distance from the center of the beam, and ω 0 is the radius at which the amplitude is 1/e of its value on the axis. The Fourier Transform of this equation is also a Gaussian distribution.
