Ultraviolet (UV) radiation is electromagnetic radiation (energy) of a wavelength just shorter than the violet (shortest wavelength) end of the visible light spectrum and thus with higher energy than visible light. As a result, the production of CFCs is now prohibited. ...
The wavelength \({\lambda }_{n}\) is defined as $${\lambda }_{n}={\lambda }_{0}{\xi }^{-n}$$ (3) The large length scale \({\lambda }_{0}\) which is equal to the system size is subdivided into smaller length scales \({\lambda }_{n}\) by integer powers of \(\...
The response depths of the elements in the sample material depend on the wavelength of the fluorescent radiation and the chemical composition of the matrix (Jenkins and De Vries, 1970). For the light elements Al and Si, this depth is about a few μm, for Ca several tenths of μm, and...
LST is influenced by the thermal distribution, emissivity in a pixel, and the wavelength range of measurement39. The DN (Digital Number) was converted to spectral radiances (L) using the equation by35,40. $$Temperature= K2/(log (K1/radiance) +1)) - 273.15$$ (1) $$Radiance \, L\...
Light wavelength of less than 190 nm is required for efficient degradation of fluorinated substances. However, chemical catalysts/reagents such as Fe3+, TiO2, S2O82−, CO32−, and IO4- together with UV can efficiently degrade PFAS due to formation of reactive and potent oxidative species ...
Subsequently, a method of determining the 0-0 band is described. In the present invention, the 0-0 band is defined as the maximum emission wavelength appearing in the shortest wavelength portion in the phosphorescence spectrum chart obtained via the above measurement method. ...
A method and apparatus is described for producing high brightness, e.g. multicolor light, whereby a region of a wavelength conversion element and a light source producing excitation
17.The diffractive optical element according to claim 1 configured to operate in a wavelength selective switch. 18.The diffractive optical element according to claim 17 wherein the input optical signal includes a plurality of optical wavelength channels. ...
Suitable substrate materials include polymers, glass and other materials that are substantially transparent in the visible wavelength spectrum. Tints, pigments, dyes or light absorbing particles can be added to the substrate or thick region to provide ambient light absorption and an increase in contrast...
travels into the optical waveguide layer and the light of which wave-length is different from the spectrum of the color of the included pigment filters is mostly absorbed, though, for example, the light which has the wavelength corresponding to the red-color light can penetrate the optical waveg...
