Fraunhofer diffraction from gratings In this exercise we use a two
... In this exercise we use a two-dimensional grating consisting of many straight and equidistant lines in a plane (a slide). We perform Fraunhofer diffraction which means a parallel incident beam entering the object, and we observe the diffraction pattern far away from the object. Depending on the scat ...

... Light coupling into optical fiber and integrated waveguide structure is one of the most time consuming task. Assume that the fiber has a core diameter of 100m and a NA of 0.25, and trhe design requires that the total distance from the source to the fiber be 100mm, which lenses are appropriate (find ...

... A convex lens is thicker in the center than on its edges. As light rays parallel to the optical axis pass through a convex lens, they are bent toward the center of the lens. Examples: Magnifying glass and corrective lenses for farsightedness. A concave lens is thinner in the center than on its edges ...

Lens (optics)
A lens is a transmissive optical device that affects the focus of a light beam through refraction. A simple lens consists of a single piece of material, while a compound lens consists of several simple lenses (elements), usually along a common axis. Lenses are made from transparent materials such as glass, ground and polished to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly refract radiation other than visible light are also called lenses, such as microwave lenses or acoustic lenses.
