Neuland Lighthouse
Neuland Lighthouse (german: Leuchtturm Neuland) is a lighthouse in the north German state of Schleswig-Holstein on the Baltic Sea coast that was in service from 1918 to 1996. It stands on the western shore of Hohwacht Bay about 1 kilometre north of the village of Behrensdorf. History The lighthouse was built in 1915/16 and taken into service in 1918. It is built of brick and is 40 metres high. The light is 40 metres above sea level. The original red and white exterior paint was removed in 1985 when the tower underwent a modernisation. The original lens was a Fresnel lens with a focus of 400 m. It was replaced by a rotating mirror optic in 1996 when the regular light was deactivated and the tower was transferred to the German Navy. The tower has since been used as a warning light displaying red and yellow signals when live firing is conducted in the military training grounds at Hohwacht Bay.

Hohwacht Bay
Hohwacht Bay (german: Hohwachter Bucht) is a wide bay in the state of Schleswig-Holstein on Germany's Baltic Sea coastline. It is named after the village and seaside resort of Hohwacht. The nearest large town is Oldenburg in Holstein, about 5 kilometres inland. A number of nature reserves fringe the bay and there is a military training area along its eastern shore. On the western shore, about 1 kilometre north of Behrensdorf, stands the ninety-year-old Neuland Lighthouse Neuland Lighthouse (german: Leuchtturm Neuland) is a lighthouse in the north German state of Schleswig-Holstein on the Baltic Sea coast that was in service from 1918 to 1996.

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schleswig-Holstein
Schleswig-Holstein (; da, Slesvig-Holsten; nds, Sleswig-Holsteen; frr, Slaswik-Holstiinj) is the northernmost of the 16 states of Germany, comprising most of the historical duchy of Holstein and the southern part of the former Duchy of Schleswig. Its capital city is Kiel; other notable cities are Lübeck and Flensburg. The region is called ''Slesvig-Holsten'' in Danish and pronounced . The Low German name is ''Sleswig-Holsteen'', and the North Frisian name is ''Slaswik-Holstiinj''. In more dated English, it is also known as ''Sleswick-Holsatia''. Historically, the name can also refer to a larger region, containing both present-day Schleswig-Holstein and the former South Jutland County (Northern Schleswig; now part of the Region of Southern Denmark) in Denmark. It covers an area of , making it the 5th smallest German federal state by area (including the city-states). Schleswig was under Danish control during the Viking Age, but in the 12th century it escaped full control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focus (optics)
In geometrical optics, a focus, also called an image point, is a point where light rays originating from a point on the object converge. Although the focus is conceptually a point, physically the focus has a spatial extent, called the blur circle. This non-ideal focusing may be caused by aberrations of the imaging optics. In the absence of significant aberrations, the smallest possible blur circle is the Airy disc, which is caused by diffraction from the optical system's aperture. Aberrations tend to worsen as the aperture diameter increases, while the Airy circle is smallest for large apertures. An image, or image point or region, is in focus if light from object points is converged almost as much as possible in the image, and out of focus if light is not well converged. The border between these is sometimes defined using a "circle of confusion" criterion. A principal focus or focal point is a special focus: * For a lens, or a spherical or parabolic mirror, it is a point ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Navy
The German Navy (, ) is the navy of Germany and part of the unified ''Bundeswehr'' (Federal Defense), the German Armed Forces. The German Navy was originally known as the ''Bundesmarine'' (Federal Navy) from 1956 to 1995, when ''Deutsche Marine'' (German Navy) became the official name with respect to the 1990 incorporation of the East German ''Volksmarine'' (People's Navy). It is deeply integrated into the NATO alliance. Its primary mission is protection of Germany's territorial waters and maritime infrastructure as well as sea lines of communication. Apart from this, the German Navy participates in peacekeeping operations, and renders humanitarian assistance and disaster relief. It also participates in anti-piracy operations. History The German Navy traces its roots back to the ''Reichsflotte'' (Imperial Fleet) of the revolutionary era of 1848–52. The ''Reichsflotte'' was the first German navy to sail under the black-red-gold flag. Founded on 14 June 1848 by the orders o ...
