An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other. Such fibers find wide usage…

An optical instrument is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic…

of optical elements remains stable over time. Many optical systems require that vibration of optical elements be kept small. As a result, optical tables…

Transitions Optical is a U.S.-based company known for manufacturing photochromic lenses, which darken on exposure to specific types of light. The company…

An optical axis is an imaginary line that passes through the geometrical center of an optical system such as a camera lens, microscope or telescopic sight…

An optical transistor, also known as an optical switch or a light valve, is a device that switches or amplifies optical signals. Light occurring on an…

Optical phenomena are any observable events that result from the interaction of light and matter. All optical phenomena coincide with quantum phenomena…

An optical comparator (often called just a comparator in context) or profile projector is a device that applies the principles of optics to the inspection…

Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about…

Optical materials are transparent materials from which optical lenses, prisms, windows, waveguides, and second-surface mirrors can be made. They are required…

In optics, optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror…
