image clarity and sharpness, particularly in low-contrast situations. This upgrade enhances operator safety and efficiency by providing a clearer overall perception. The advanced image processing in the upgraded K-Series brings notable improvements in image quality across the entire imaging spectrum. ...

After ∼1 microsecond the excited state absorption spectrum is clearly discernable from spectra at earlier times (Fig. S15) and persists essentially unchanged, except for a decay in intensity, for hundreds of microseconds (Fig. 3-A). This long-lived feature strongly resembles the spectro...

The infrared part of the light spectrum is just below the visible spectrum, the name “infrared” actually means “below red” which is where they sit on a spectrum chart. This is the opposite of ultraviolet or UV light which is just above the visible spectrum, “ultraviolet” meaning “abo...
dating over 20 years ago, then we reinvented the category by launching Tinder, and we are now evolving our diverse portfolio of apps so that we can continue to lead the way in helping people make meaningful connections across the spectrum of age, race, gender, sexual orientation and ...
The tristimulus values are arrived at by integrating over the visible spectrum. The color matching functions and the corresponding tristimulus values are shown below: Average Gain 1 2.0 10000 1.8 Z 1.6 1.4 1000 1.2 1.0 Y X 0.8 0.6 100 0.4 0.2 0 10 350 400 450 500 550 600 650 700 750 ...
AA. Despite the breadth of IR bands, the IR spectra of molecules are so complex that no 2 compounds with different structures have the same IR spectrum except for optical isomers and certain high molecular weight polymers differing only slightly in molecular weight. IR spectrometers are scanning ...
In the spectra of trans o-coumaric acid and its metal salts bands from the hydroxyl group attached to the aromatic ring are present: (1) in the spectrum of the acid: νOHar 3356 cm−1 (IR), 3837 cm−1 (theoret.); νC-OHar 1219 cm−1 (IR), 1225 cm−1 (Raman), 1274...
