Norita
was a Japanese optical manufacturer. Founded in 1951 by Toshio Norita (), it originally made lenses for binoculars but moved on to prisms and thence pentaprisms for SLR cameras.Hagiya Takeshi (), "Norita 66: Yūshutsu o mein toshita 6×6 cm-ban ichiganrefu" (, Norita 66: A 6×6 SLR mainly for export); chap. 4 (pp. 79–90) of Hagiya's ''Zunō kamera tanjō: Sengo kokusan kamera jū monogatari'' (, The birth of the Zunow camera: Ten stories of postwar Japanese camera makers; Tokyo: Asahi Sonorama, 1999; ), p.82. Musashino Kōki () had been making a 6×6 SLR called the Rittreck 6×6 from 1968; for which Norita had been making the pentaprism finder and the three lenses (wide, standard, and tele). When Musashino decided to terminate production of this camera, Norita decided to expand from being merely an optical designer/manufacturer to manufacturing cameras, and took over machine tools, assembly, and some staff from Musashino. For its new "Norita 66", Norita expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graflex
Graflex was a manufacturer that gave its brand name to several models of camera. The company was founded as the ''Folmer and Schwing Manufacturing Company'' in New York City in 1887 by William F. Folmer and William E. Schwing as a metal working factory, manufacturing gas light fixtures, chandeliers, bicycles and eventually, cameras. In 1909, it was acquired by George Eastman, and the company was moved to 12 Caledonia Avenue (later renamed Clarissa Street), Rochester, NY in 1928, as the Folmer & Schwing Division of the Eastman Kodak Company. In 1926, Kodak was forced to divest itself of the division, which was spun off forming a new company, the Folmer Graflex Corporation, which changed its name to Graflex Inc. in 1946. In 1956, it became a Division of the General Instrument Precision Company, and moved its offices to Pittsford, NY. In 1968, the company was sold to the Singer Corporation. Graflex was known for the quintessential press camera, the Speed Graphic which was manufactu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ...

Japan
Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north toward the East China Sea, Philippine Sea, and Taiwan in the south.

Single-lens Reflex
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.

Singer Corporation
Singer Corporation is an American manufacturer of consumer sewing machines, first established as I. M. Singer & Co. in 1851 by Isaac M. Singer with New York lawyer Edward C. Clark. Best known for its sewing machines, it was renamed Singer Manufacturing Company in 1865, then the Singer Company in 1963. It is based in La Vergne, Tennessee, near Nashville. Its first large factory for mass production was built in 1863 in Elizabeth, New Jersey. History Singer's original design was the first practical sewing machine for general domestic use. It incorporated the basic eye-pointed needle and lock stitch, developed by Elias Howe, who won a patent-infringement suit against Singer in 1854. Singer obtained in August 1851 for an improved sewing machine that included a circular feed wheel, thread controller, and power transmitted by gear wheels and shafting. Singer consolidated enough patents in the field to enable him to engage in mass production, and by 1860 his company was the la ...

Cameras
A camera is an optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera domain are film, videography, and cinematograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
