[1] [2] This side of the disc contains the actual data and is typically coated with a transparent material, usually lacquer. The reverse side of an optical disc usually has a printed label, sometimes made of paper but often printed or stamped onto the disc itself.
Beginning in 2007, prerecorded Blu-ray and HD DVD titles ship in packages similar to but slightly smaller (18.5 mm shorter and 1 mm thinner: 135 mm × 171.5 mm × 13 mm) [31] than a standard DVD keep case, generally with the format logo prominently displayed in a horizontal stripe across the top of the case (red for HD DVD; and PlayStation 3 ...
Optik: International Journal for Light and Electron Optics, or simply Optik (German for Optics) is a peer-reviewed scientific journal covering the optics of light and electrons. According to the Journal Citation Reports , the journal has a 2021 impact factor of 3.1.
In the Book of Optics, al-Haytham hypothesized the existence of primary and secondary light, with primary light being the stronger or more intense of the two.The book describes how the essential form of light comes from self-luminous bodies and that accidental light comes from objects that obtain and emit light from those self-luminous bodies.
Meyer Optik USA is headquartered in Atlanta, GA. That same year, net SE - Globell Deutschland launched a Kickstarter campaign to produce the Trioplan f2.9/50, a special new lens that revived the tradition of a versatile "soap-bubble" bokeh lens. Successive kickstarter lens campaigns collectively raised approximately $2.5 million. [1]
A condenser (right) and its respective diaphragm (left). A condenser is an optical lens that renders a divergent light beam from a point light source into a parallel or converging beam to illuminate an object to be imaged.
Military based studies consistently produce longer estimates for reliability, projecting the maximum range for terrestrial links is of the order of 2 to 3 km (1.2 to 1.9 mi). [9] All studies agree the stability and quality of the link is highly dependent on atmospheric factors such as rain, fog, dust and heat.
The cladding causes light to be confined to the core of the fiber by total internal reflection at the boundary between the core and cladding. [1] Light propagation within the cladding is typically suppressed for most fibers. However, some fibers can support cladding modes in which light propagates through the cladding as well as the core.
