What element was first discovered in the spectrum of the sun before it was discovered on earth? Spectrum: The spectrum of an element is a set of spectral lines emitted by a source (element) in ascending and descending order of energy, wavelength, or frequency. ...
3. The apparatus of claim 1, wherein said light source generates light of a non-visible wavelength, the apparatus further comprising: (a) an image projector coupled to said first LOE so as to introduce a collimated image into said first LOE such that said collimated image propagates via int...
A light emitting device is produced by depositing a layer of wavelength converting material over the light emitting device, testing the device to determine the wavelength spectrum produced and correcting the wavelength converting member to produce the desired wavelength spectrum. The wavelength converting...
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 \(\...
[0045] FIG. 15 is a graph illustrating the variation of reflectivity of the human retina as a function of wavelength over the visible light and infrared regions of the spectrum; [0046] FIG. 16 is a graph illustrating the wavelength responsiveness of the different types of cone photo-receptors...
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...
Further, in the case where the retardation film is used along with an absorption color filter, the wavelength of light is preferably in the proximity of, more preferably equal to, the wavelength at which the transmittance of the color filter to be used peaks in the spectrum shown in FIG. ...
A substance which has favorable light emission efficiency and can emit light with desired emission wavelength may be used as the light emitting substance. For example, in order to obtain red light emission, a substance which exhibits light emission having a peak of an emission spectrum at 600 ...
Moreover, since no guiding of the light in the optical waveguide layer can provide no improvement of external coupling efficiency, the thickness of the optical waveguide layer should be larger than the wavelength of the light so that the good propagation of the light is obtained. For this ...
FIG. 3 is a beam spectrum provided by the apparatus shown in FIG. 2; FIG. 4 is a chart showing results of a Raman spectroscopic analysis of an amorphous film of carbon; FIG. 5 is a photograph of the surface of the amorphous film of carbon by an interatomic force microscope; ...
