Absorbance values often depend on the optical wavelength.Note that optical attenuation e.g. of a neutral density filter may not be entirely resulting from absorption, but at least partially from reflection; the term absorbance is then questionable....
It is assumed, however, that due to the use of two detectors from the same series, the relative change in sensitivity between the detectors is the same. The same offset cancels possible measurement error because it appears both in the numerator and the denominator of the formula used to ...
摘要: A quadratic formula that accurately represents general absorptance is both developed for 5 cm(-1) data on the 4upsilon(2) + upsilon(3) band of CO(2) centered at 4853.58 cm(-1) and generalized to a polynomial function of the weak- and strong-line limits of known models. DOI: 10...
VLT may alternately be expressed as absorbance, and may optionally include reference to one or more wavelengths that are absorbed. According to some embodiments, an optical filter may be selected, or configured to have in the dark state, a VLT of less than 80%, or less than 70%, or less...
x(λ) is the absorbance of the film, as the subscripts “f”, “s” and “a” refer to the film, the substrate and the air, respectively. It was assumed in the derivation of Equation (1) that the film thickness d has a continuous uniform distribution in the interval [d d¯ −...
UV-VIS-IR spectroscopy is a well-established technique for the identification of the coloring agents (chromophores) in stained glass windows, whereby the specific absorbance peaks in the spectra can be analyzed and interpreted [2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22...

The AUP for road marking paint should have good optical clarity to ensure the effective absorbance and high reflection of road paint bead. Figure 5 shows the UV-visible spectra of the AUP series with different t-AU contents. The transmittance values of most AUPs were more than 90%, showing...
