II-VI Incorporated
Coherent Corp. (formerly II-VI Incorporated) is an American manufacturer of optical materials and semiconductors. As of 2023, the company had 26,622 employees. Their stock is listed at the New York Stock Exchange under the ticker symbol COHR. In 2022, II-VI acquired laser manufacturer Coherent, Inc., and adopted its name. History Coherent was founded as II-VI Incorporated in 1971 by Carl Johnson and James Hawkey. The name "II-VI" is a reference to the groups II and VI in the periodic table, since the company started its business by producing cadmium telluride (cadmium belongs to alkaline earth metal, group II and tellurium belongs to chalcogen, group VI). The company's first products included lenses, windows, and mirrors for carbon-dioxide laser, CO lasers. The company held its initial public offering in 1987. According to Carl Johnson, the funds raised by the IPO allowed II-VI to expand its zinc selenide manufacturing capacity. In the 1990s, the company began to grow both on ...

Face ID
Face ID is a Biometrics, biometric authentication facial recognition system, facial-recognition system designed and developed by Apple Inc. for the iPhone and iPad Pro. The system can be used for unlocking a device, making Apple Pay, payments, accessing sensitive data, providing detailed Facial motion capture, facial expression tracking for Animoji, as well as six degrees of freedom (6DOF) head-tracking, eye-tracking, and other features. Initially released in November 2017 with the iPhone X, it has since been updated and introduced to all iPhones outside of IPhone SE, SE models and all iPad Pro models from 2018 onwards. Users on iOS 18 and newer can choose to lock specific apps, requiring Face ID to access them. The Face ID hardware uses a TrueDepth Camera that consists of a sensor with three modules; a laser dot projector that projects a grid of small infrared dots onto a user's face, a module called the flood illuminator that shines infrared light at the face, and an infrared ca ...

Subsidiary
A subsidiary, subsidiary company, or daughter company is a company (law), company completely or partially owned or controlled by another company, called the parent company or holding company, which has legal and financial control over the subsidiary company. Unlike regional branches or divisions, subsidiaries are considered to be distinct entities from their parent companies; they are required to follow the laws of where they are incorporated, and they maintain their own executive leadership. Two or more subsidiaries primarily controlled by same entity/group are considered to be sister companies of each other. Subsidiaries are a common feature of modern business, and most multinational corporations organize their operations via the creation and purchase of subsidiary companies. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, and Citigroup, which have subsidiaries involved in many different Industry (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical-cavity Surface-emitting Laser
The vertical-cavity surface-emitting laser (VCSEL ) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also called ''in-plane'' lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer. VCSELs are used in various laser products, including computer mice, fiber-optic communications, laser printers, Face ID, and smartglasses. Production advantages There are several advantages to producing VCSELs, in contrast to the production process of edge-emitting lasers. Edge-emitters cannot be tested until the end of the production process. If the edge-emitter does not function properly, whether due to bad contacts or poor material growth quality, the production time and the processing materials have been wasted. VCSELs however, can be tested at several stages throughout the process to check for material quality and processing issues. For instanc ...

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 instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and 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, however complete electromagnetic descriptions of light are 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 ...
