Sejarah awal
In 1942, amateur photographer Norman W. Edmund (1916 - 2012) found it difficult to find the lens he needed for his hobby. This makes it advertise the lens for sale in photography magazines. It was so successful he founded "'Edmund Salvage Corporation'". It immediately changed its name to Edmund Scientific and made its name with advertisements in publications such as Scientific American as a supplier of lens stoppers, war-surplus optics, and cheap scientific gadgets. His ad attracted the attention of fans, amateur astronomers, high school students, and under-funded researchers.
War surplus
Edmund Scientific is part of the phenomenon of "post-war surplus war", when the US government sells a large amount of material. "Army and Navy Stores" is a national phenomenon and originally sold military surplus clothing. Electronic surplus finds outlets in dozens of stores, in "Radio Row" New York City and elsewhere. Some catalogs are published and develop a national mail-order business. Edmund is, however, the only widely known optical supplier of surplus.
The point of Edmund's offering is a surplus lens. This is a single element lens, sent in a 2.5-by-4.25 inch (64 mm) coin envelope, with an estimated diameter and the focal length is on them. Reflecting their original salvage and surplus, the available diameter and focal length did not fall into regular development. Edmund publishes "books" that are roughly printed and clipped that illustrate experiments that can be done with their lenses, and plans to build telescopes and other optical equipment. Edmund also sells "kit" lenses. The 10-lens valuable package is less than US $ 10 and includes a plan booklet for the instruments that should be built with them.
Unlike Heathkits, a truly complete kit that requires just soldering and assembling, Edmund's "kit" consists only of lenses. The enormous skill and effort required to create the telescope, microscope, or opaque projector are described. With one element lens, the resulting optical quality is not high. Edmund even sells the high-quality, thick, black cardboard tubes needed for many projects.

Following Sputnik, Edmund was able to capitalize on the growing national interest in science and astronomy. They expanded their business into a full line of telescopes and telescope equipment as well as equipment, parts, and supplies for other scientific fields such as physics, optics, chemistry, microscopy, electronics, and meteorology. They continue to grow as a supplier for teachers and schools with demonstration tools and equipment covering most areas of science.
Edmund's catalog becomes the source for the optical and mechanical parts that are essential for the manufacture of amateur telescopes, including hard-to-find objects such as optical glass, concentrated materials, and a series of sand abrasives to grind and polish astronomical destination mirrors by hand. A compilation of Edmund's earlier pamphlets published as the book "All About Telescopes" offers many designs for telescopes of all sizes and configurations, which directs builders to the relatively few parts of Edmund's catalog required for each design. The "Factory Store" in Barrington, New Jersey also has a number of trash cans and shelves filled with rare surplus items that never get into the catalog.
Edmund serves the 1960s generation by expanding and highlighting their projector lines, color wheels, black lights, filters and other optical devices that can be used by rock bands and in psychedelic light shows. Other items serving counter-culture were eventually added to the catalog covering the fields of Biofeedback, ESP, Kirlian photography, Pyramid power, and alternative energy.
In 1971, in the All Earth Catalog item "relevant to independent education", Stewart Brand noted:
"Edmund is the best source we know about cheap scientific gadgets (including mathematical and optical equipment). [In this category,] many of the items we found separately... appear in Edmund's catalog, so we are obliged to recommend that in this area we've been blocked. "
Some sources claim that certain of the original polyhedral dice used in Dungeons & amp; The Dragons role-playing game system was obtained from Edmund Scientific.
End of era
In the 1970s, as the survival of Edmund's business model diminished, Norman Edmund's son, Robert Edmund transformed his business into two new businesses, Edmund Scientifics and Edmund Optics . Edmund Scientifics is marketed to consumers and specialized in science-themed toys, highly sophisticated household gadgets, and "science gifts." Edmund Optic has no public display space like Edmund Scientifics, although both organizations share the same building. The vast backroom of Edmund Scientifics still sold military surpluses from World War II and other wars until the 1980s and into the mid-1990s. Some items in the surplus room come from other German and non-American military. None of these items are in the mail-order catalog. They also sell other surplus items that appeal to the fans, including special motors and other electronics, spare parts from toys, and other household items.
In keeping with their focus on optics, Edmund Scientifics's entrance space puts the pale blue Japanese World II submarine periscope. Children are often attracted to this periscope. Referring to the popularity of the periscope, sometimes in the 1970s, a mirror hall, complete with black lights, was installed at the rear of the building.
The Barrington store, New Jersey, was closed in 2001 after Edmund Scientific was acquired by Science Kit and Boreal Laboratories.
Beginning in 2000, Edmund Optics offers a wide range of experimental classes and stock clearance items through print and online catalogs under a separate business called Anchor Optics, but this operation stops in 2016, and the Anchor Optics website now redirects to a page in Edmund Item's license for listing optics.
In 2017, Edmund Optics continues to offer new optical shares, as well as offering specialized and specialized optics to companies and higher education institutions.
Today
In 2000 Edmund Scientific was purchased by Science Kit and Boreal Laboratories, a western-based supplier of science in New York. Science Kit and Boreal Laboratories are part of a group of companies providing science supplies for primary, secondary, and high schools as well as colleges and universities. The group is under the unofficial umbrella of "VWR Education" and is owned by VWR International, a multi-national conglomerate with offices in India, China, Europe, Canada and the United States. They are no longer affiliated with Edmund Optics Inc.
As of 2009, online sales are now the largest share of Edmund Scientific's revenue. Companies still sell telescopes (including the latest version of their Astroscan Telescope), microscopes (most of them carry the Boreal brand produced for their parent company Science Kit LLC), surplus optics, magnets and Fresnel lenses. They continue to sell many of their old favorites along with new items like Impossiball and hand boilers as well as other science-themed toys, new items, gifts and gadgets.
In movies and television
Edmund Scientific has provided items used in television shows such as Home , MythBusters , 24 , Marvel Modern and movements images like Star Trek , and the 1975 version Escape to Witch Mountain . Wah Chang, an artist who designed and built several props in the 1960s for the Star Trek television show, using the moirÃÆ' Â © pattern found in Edmund Scientific Educator and MoirÃÆ'Â © Designer Kit for textures used in the communicator Starfleet props.
In the episode of "Two Bad Neighbors" Simpsons, Bart Simpson removes the grasshopper from the box labeled Edmund Scientific .
