FWHM

abbreviation for full-width half maximum.

full width half maximum

FWHM

The width of a peak or the bandpass of an emission or absorption spectrum in a laboratory photometer or spectrophotometer. When combined with other characteristics of the device, this can be used to predict suitability of the photometer or spectrophotometer for specific applications and measurements.

The FWHM values showed a similar pattern with the demineralized enamel sample having a width of only 455.
In Table 1, the manual ROI method was found to produce AIFs with different TTP, arrival time, FWHM, and peak height.
The difference between the two FWHMs may be slight at most time, but when in spectroradiometry applications, the effective FWHM acts more in deriving the exact spectral radiance intensity.
For the change of A by -3%, we could achieve a broadband SCG as shown in Figure 13 with reduced FWHM of 315 nm.
Figure 1(b) shows that the FWHM of the radial polarization is larger than the circular polarization when the annulus ratio is less than 0.

Los refinamientos de los difractogramas fueron hechos mediante el uso del metodo Rietveld, con el objetivo de obtener el FWHM de los picos, observando que el pico (200) de (Ti,Al)N se superpone con el pico (110) de hierro que pertenece al sustrato.
The 4G acquires up to 50 averaged spectra per second with mass resolving power of 8,000 FWHM and high mass accuracy, and is compatible with commercially available 2D GC systems for GCxGC/EI and GCxGC/FI.
The effective length, maximum intensity, and full-width half-maximum of the photonic nanojet are L, I, and FWHM, respectively.
Then, in the result section, we study the effect of the FWHM of homogeneous broadening and the injected current on the rise and fall time, hence on the bit rate.
