Lyngvig Fyr, Lighthouse Lighthouse Fresnel lense, we see the top glashouse from Lyngvig-Lighthouse. A system of lenses and prisms – a combined Fresnel lens – condenses light from the lighting assembly . Four of these lens systems are mounted on a grid of brass. The combine four constant light rays. The whole system is rotating about a vertical axis. The total lantern floating on a ring-shaped vessel filled with mercury . Lanternen foot forming a lid on this vessel . This device provides an almost frictionless movement of the lantern . In order to avoid evaporation must kerosene is poured over the mercury. The boiler personnel should constantly pouring kerosene…

we see the top glashouse from Hirtshals-Lighthouse. Hirtshals Lighthouse The lighthouse Hirtshals is located in Northern Jutland (Denmark) A Fresnel lens is an optical lens, which was invented by Augustin-Jean Fresnel. Originally developed for lighthouses, enables the design principle of the construction of large lenses with short focal length without the weight and volume of conventional lenses. The reduction in volume occurs at the Fresnel lens by a division into annular regions. In each area, the thickness is reduced, so that the lens is replaced by a series of annular steps. Since light is broken only at the surface of the lens, the refractive angle is not on the thickness,…
