Web20. júl 2011 · When trying to intensify a beam of light by refracting it through a lens, (as in a lighthouse fresnel system or similar railroad style switch lamp from years past), is the beam intensity increased by moving the lens closer to the beam? That is, refracting it as close as possible to the light source? WebA lens is a piece of glass or other transparent substance that refracts light. A lens concentrates or disperses rays of light when passed through them by refraction. There are two main kinds of lenses: Concave lens and Convex lens. Concave lens: A concave lens is thin in the middle and thicker at the edges. It is shaped like a cave.
