Fiber Bragg grating — A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the… … Wikipedia
Diffraction grating — A very large reflecting diffraction grating. In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. The directions of these beams … Wikipedia
Reflectivity — In photometry and heat transfer, reflectivity is the fraction of incident radiation reflected by a surface. In full generality it must be treated as a directional property that is a function of the reflected direction, the incident direction, and … Wikipedia
Spectrophotometry — Spectrophotometer In chemistry, spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.[1] It is more specific than the general term electromagnetic spectroscopy in … Wikipedia
Monochromator — in a x ray beamline at the Advanced Photon Source, Argonne National Laboratory. A monochromator is an optical device that transmits a mechanically selectable narrow band of wavelengths of light or other radiation chosen from a wider range of… … Wikipedia
Ultraviolet–visible spectroscopy — Beckman DU640 UV/Vis spectrophotometer. Ultraviolet visible spectroscopy or ultraviolet visible spectrophotometry (UV Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet visible spectral region. This… … Wikipedia
