Security Equipment Manufacturers
Security is protection from, or resilience against, potential harm (or other unwanted coercive change) caused by others, by restraining the freedom of others to act. Beneficiaries (technically referents) of security may be of persons and social groups, objects and institutions, ecosystems or any other entity or phenomenon vulnerable to unwanted change. Security mostly refers to protection from hostile forces, but it has a wide range of other senses: for example, as the absence of harm (e.g. freedom from want); as the presence of an essential good (e.g. food security); as resilience against potential damage or harm (e.g. secure foundations); as secrecy (e.g. a secure telephone line); as containment (e.g. a secure room or cell); and as a state of mind (e.g. emotional security). The term is also used to refer to acts and systems whose purpose may be to provide security (security companies, security forces, security guard, cyber security systems, security cameras, remote guarding ...

Optics Manufacturing Companies
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of optical instruments, instruments that use or Photodetector, detect it. Optics usually describes the behaviour of visible light, 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 electromagnetism, 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 Ray (optics), rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photography Companies Of Japan
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...

Lens Manufacturers
A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (''elements''), usually arranged along a common axis. Lenses are made from materials such as glass or plastic, and are ground and polished or molded to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses. Lenses are used in various imaging devices like telescopes, binoculars and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia. History The word ''lens'' comes from '' lēns'', the Latin name of the lentil (a seed of a lentil plant), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manufacturing Companies Of Japan
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final produc ...

List Of Tokina Lenses With Nikon F-mount And Integrated Autofocus Motor
The following list of Nikon F-mount lenses with integrated autofocus motor includes only Nikon F-mount lenses which fully autofocus in all modes of all Nikon F-mount digital single-lens reflex cameras with and also ''without'' an autofocus motor. Cameras lacking an integrated autofocus motor are the Nikon D40, D40X, D60, Nikon D3xxx series (the latest model of which is the D3500), Nikon D5xxx series (the latest model of which is the D5600) and all Nikon 1 series cameras with FT1 adapter. Fully supporting these cameras all AF-S (introduced 1996), AF-P (introduced 2015), and the older AF-I (introduced 1992) Nikon Nikkor lenses are clearly designated including the necessary autofocus motor. Other manufacturers have different or ''no designations'' for lenses including a focus motor. All here not listed AF lenses without an autofocus motor do work fully, but lack autofocus-function on these cameras. Instead an electronic rangefinder can be used to find focus.

List Of Photographic Equipment Makers
This list of photographic equipment makers lists companies that manufacture (or license manufacture from other companies) equipment for photography. Camera and lens manufacturers Note that producers whose only presence in the photo industry at any time has been the manufacture of digital cameras (Logitech, for example, which has made Webcams) are listed separately on the List of digital camera brands. There is not a very clear distinguishing line between camera producers and lens producers; many companies do both, or have done both at one time or another. Some camera manufacturers sell lenses made by others as their own, in an OEM arrangement. Some camera makers design lenses but outsource manufacture. Some lens makers have cameras made to sell under their own brand name. A few companies are only in the lens business. Some camera companies make no lenses, but usually at least sell a lens from some lens maker with their cameras as part of a package. Note that many optical inst ...
