Petit Manan Light
Petit Manan Light is a lighthouse on Petit Manan Island, Maine. The island is at the end of a series of ledges extending out from Petit Manan Point, between Dyer Bay and Pigeon Hill Bay, that projects into the Gulf of Maine. Description The Petit Manan light station consists of a light tower, keeper's house, boathouse, and other outbuildings. The tower is a circular granite stone structure, in height and in diameter at its base. Atop this is mounted a two-story twelve-sided lantern house, placing the light's focal plan at . The inside of the tower is lined with brick, and has iron stairs. The keeper's house is a two-story wood frame structure. Accompanying outbuildings include a rain shed (possibly built in 1868), paint shed (1876), generator building (1887), and boathouse (probably built 1868, and enlarged 1900). History It was first established in 1817 as a small stone lighthouse. The present structure was built in 1855, and the keeper's house in 1875. The original le ...

Atlantic Puffin
The Atlantic puffin ('), also known as the common puffin, is a species of seabird in the auk family. It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin is found in the northeastern Pacific. The Atlantic puffin breeds in Russia, Iceland, Ireland, Norway, Greenland, Newfoundland and Labrador, Nova Scotia, and the Faroe Islands, and as far south as Maine in the west and France in the east. It is most commonly found in the Westman Islands, Iceland. Although it has a large population and a wide range, the species has declined rapidly, at least in parts of its range, resulting in it being rated as vulnerable by the IUCN. On land, it has the typical upright stance of an auk. At sea, it swims on the surface and feeds on small fish and crabs, which it catches by diving underwater, using its wings for propulsion. This puffin has a black crown and back, pale grey cheek patches, and a white body and underparts. Its broad, bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses In Washington County, Maine
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 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boon Island Light
Boon Island Light is located on the Boon Island off the southern coast of Maine, United States, near Cape Neddick. Boon Island Light has the distinction of being the tallest lighthouse in both Maine and New England at . The lighthouse has a focal plane at above mean high water. The light's beacon flashes white every 5 seconds. History Talk of building a lighthouse on Boon Island dates back as early as 1710 when the ship ''Nottingham Galley'' ran aground on the barren outcrop that makes up the island. The crew of the ''Galley'' were forced to resort to cannibalism before being rescued. In 1799 the first day marker and a 50-foot wooden tower were established on the island, but it was washed away in the first 5 years. A stone day beacon was established in its place. In 1811 the station was converted to a full light station and a granite tower was constructed. This first tower was washed away in a storm in 1832. The current 133 foot cylindrical brown granite tower was constructed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rockland, Maine
Rockland is a city in Knox County, Maine, in the United States. As of the 2020 census, the town population was 6,936. It is the county seat of Knox County. The city is a popular tourist destination. It is a departure point for the Maine State Ferry Service to the islands of Penobscot Bay: Vinalhaven, North Haven and Matinicus. History Abenaki Indigenous People called it Catawamteak, meaning "great landing place." In 1767, John Lermond and his two brothers from Warren built a camp to produce oak staves and pine lumber. Thereafter known as Lermond's Cove, it was first settled about 1769. When in 1777 Thomaston was incorporated, Lermond's Cove became a district called Shore village. On July 28, 1848, it was set off as the town of East Thomaston. Renamed Rockland in 1850, it was chartered as a city in 1854. Rockland developed rapidly because of shipbuilding and lime production. In 1854 alone, the city built eleven ships, three barks, six brigs and four schooners. The city ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VRB-25
The VRB-25 is a lighthouse optical system designed and built by Vega Industries Ltd. in Porirua, New Zealand. It was originally designed in 1993-95 with the assistance of the United States Coast Guard to meet USCG requirements for a robust mechanism requiring minimum maintenance. It has become the Coast Guard's standard 12 volt rotating beacon. The company's literature says there are more than 400 installations worldwide. More than a quarter of the active lighthouses in Maine have one installed. Components A microprocessor controlled 12 volt DC motor drives an array of six or eight acrylic Fresnel lenses around a bulb at one of 248 speeds ranging from 0.5 to 15.9 revolutions per minute (RPM). In the simplest case, all six lenses are used, so that for Boon Island Light, which shows one flash every five seconds, the mechanism rotates at two RPM. Eight lenses are used only when required to achieve more complex characteristics. Maximum range is achieved by using the slowest p ...

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.
