Point Amour Lighthouse
The Point Amour Lighthouse is a lighthouse located on Point Amour in southern Labrador, Canada. It is not far from L'Anse Amour, and was completed in 1857. It is the tallest lighthouse in Atlantic Canada, and the second tallest one in all of Canada, reaching a height of 109 feet (33m). The Point Amour Lighthouse was part of a series of four lighthouses built in the 1850s to allow for safer passage for the increased steamship travel between Europe and the new world at that time. The cylindrical tower is built of limestone and is painted white with a black band. The limestone used for construction of the lighthouse was obtained from local quarries. Other materials such as timber and brick were not as accessible and were shipped from Quebec to L’Anse au Loup. From L’Anse au Loup they were brought to the sight where the lighthouse was constructed, four miles away. It was built in the series of Imperial Towers and is designated a Provincial Historic Site.

L'Anse Amour
L'Anse Amour () is a small village on the Strait of Belle Isle in Labrador, a part of the Canadian province of Newfoundland and Labrador. As of 2006, it had a population of 8 (1996), down from a total of 14 returned five years earlier. The settlement has not been returned separately since, though the 'between communities' population of Subdivision 10A has grown in the intervening years to a total of 20 by 2016 (up from 10 in 2011), of which L'Anse Amour may reasonably be assumed to contain much of it. L'Anse Amour is located along Route 510 (Trans-Labrador Highway). Demographics The figures below pertain to Division No. 10, Subd. A, which includes L'Anse Amour. * Population, 2001: 64 * Population, 1996: 83 * Population change, 1996-2001: -22.9 percent * Area (square kilometers): 3,755.19 * Number of families: 25 No statistics for the town of L'Anse Amour itself are available, though tourist Web sitelists the town's population at 8.

Focal Plane
In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system. These are the '' focal points'', the principal points, and the nodal points. For ''ideal'' systems, the basic imaging properties such as image size, location, and orientation are completely determined by the locations of the cardinal points; in fact only four points are necessary: the focal points and either the principal or nodal points. The only ideal system that has been achieved in practice is the plane mirror, however the cardinal points are widely used to ''approximate'' the behavior of real optical systems. Cardinal points provide a way to analytically simplify a system with many components, allowing the imaging characteristics of the system to be approximately determined with simple calculations. Explanation The cardinal points lie on the optical axis of the optical system. Each point is defined by the effect the opti ...

Lighthouse Museums In Canada
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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Museums In Newfoundland And Labrador
A museum ( ; plural museums or, rarely, musea) is a building or institution that cares for and displays a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance. Many public museums make these items available for public viewing through exhibits that may be permanent or temporary. The largest museums are located in major cities throughout the world, while thousands of local museums exist in smaller cities, towns, and rural areas. Museums have varying aims, ranging from the conservation and documentation of their collection, serving researchers and specialists, to catering to the general public. The goal of serving researchers is not only scientific, but intended to serve the general public. There are many types of museums, including art museums, natural history museums, science museums, war museums, and children's museums. According to the International Council of Museums (ICOM), there are more than 55,000 museums in 202 countries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, ...

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.
