central wavelengthの例文

• Both of these filters can also be made tunable, such that the central wavelength can be chosen by the user.
• Where ? 0 is the central wavelength of the nearest transmission peak and n _ \ mathrm { g } is the group refractive index.
• Typical values for SLED modules are for the BW between 5 nm and 100 nm with central wavelengths covering the range between 400 nm and 1700 nm.
• However, when the angle of incidence of the incoming light is increased from zero, the central wavelength of the filter decreases, resulting in partial tunability.
• In practice, however, the geometry is chosen such that the incident and refracted beam have the same angle at the central wavelength of the spectrum to be compressed.
• The efficiency of fiber Bragg grating based fiber optic sensors can be provided by means of central wavelength adjustment of light emitting source in accordance with the current Bragg gratings reflection spectra.
• If ? " c " is the central wavelength, ? 0 is the central wavelength at normal incidence, and " n " * is the filter effective index of refraction, then:
• If ? " c " is the central wavelength, ? 0 is the central wavelength at normal incidence, and " n " * is the filter effective index of refraction, then:
• These are particularly suitable for local and red-shifted H-alpha studies, having nominal central wavelengths of 656.3, 660.3, 664.3, 668.3 and 672.3.
• Where \ lambda is the central wavelength of the source, n is the refractive index of the FWHM spectral width \ Delta \ lambda, then a path offset of ?L will reduce the fringe visibility to 50 %.
• ANS also observed in the ultraviolet part of the spectrum, with a 22 cm ( 260 cm 2 ) nm, with the detector split into five channels with central wavelengths of 155, 180, 220, 250 and 330 nm.
• Where ? 0 is the central wavelength of the nearest transmission peak, " n " is the index of refraction of the cavity medium, \ theta is the angle of incidence, and l is the thickness of the cavity.
• The mean frequency \ nu _ 0 = c / \ lambda _ 0 can be expressed by the central wavelength, and the effective bandwidth by means of the coherence length, L _ { c } = c / \ pi \ Delta \ nu.
• These divergences can be more or less evident depending on the filters used : narrow filters with central wavelength located in regions without lines, will produce a response close to the black body one, and even filters centered at lines if they are broad enough, can give a reasonable blackbody-like behavior.
• The concept of high contrast grating took off with a report on a broadband high reflectivity reflector for surface-normal incident light ( the ratio between the wavelength bandwidth with a reflectivity larger than 0.99 and the central wavelength is greater than 30 % ) in 2004 by Constance J . Chang-Hasnain et al ., which was demonstrated experimentally in the same year.
