Cape North Lighthouse
The Cape North Lighthouse is a cylindrical lighthouse tower with a red and white checkerboard pattern that stood at Money Point, near Cape North, Cape Breton from 1908 to 1980. While originally installed at Cape Race, Newfoundland, this tower is most commonly referred to as the Cape North Lighthouse. It now stands landlocked at the Canada Science and Technology Museum in Ottawa, Ontario, Canada. History and construction The 29 meter tall lighthouse was first installed at Cape Race point in Newfoundland in 1856 by the British Government's Trinity House, the official lighthouse authority for British waters. The lighthouse is constructed of 32 cast-iron plates joined together with bolts. This sectional, modular design was chosen to reduce the cost of building towers and to facilitate lighthouse construction in remote, inaccessible locations using local, unskilled labour. When a larger lighthouse was built at Cape Race, the old tower was disassembled, moved by ship, and reassemble ... [...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. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cape Race
Cape Race is a point of land located at the southeastern tip of the Avalon Peninsula on the island of Newfoundland, in Newfoundland and Labrador, Canada. Its name is thought to come from the original Portuguese name for this cape, "Raso", meaning flat or low-lying. The Cape appeared on early sixteenth century maps as Cabo Raso and its name may derive from a cape of the same name at the mouth of the Tagus River in Portugal. The cape was the location of the Cape Race LORAN-C transmitter until the system was decommissioned in 2010. It is also home to the Cape Race Lighthouse, notable for having received the distress call from the RMS ''Titanic''. Geography Dense fog, rocky coasts, and its proximity to trans-Atlantic shipping routes have resulted in many shipwrecks near Cape Race over the years. One of the most famous was the .
