An illustration of some of the optical devices available for laboratory work in England in 1858. 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 properties.
Phase shift through a beam splitter with a dielectric coating. Beam splitters are sometimes used to recombine beams of light, as in a Mach–Zehnder interferometer.In this case there are two incoming beams, and potentially two outgoing beams.
Cladding in optical fibers is one or more layers of materials of lower refractive index in intimate contact with a core material of higher refractive index.. 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]
Relascope usage. The Relascope is used by looking through the hole in the front of the instrument. When users look through this hole they will see several scales that are used for different measurements on the bottom half of their view, and on the top half they will see the tree that they are looking at.
A photophone receiver and headset, one half of Bell and Tainter's optical telecommunication system of 1880. Optical communications, in various forms, have been used for thousands of years.
The Schuster Laboratory, University of Manchester (a physics laboratory). A laboratory (UK: / l ə ˈ b ɒr ə t ər i /; US: / ˈ l æ b r ə t ɔːr i /; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed.
