The colors of the rainbow are all around us, but so are hues that most of us can't see, including ultraviolet — a wavelength that eludes many humans but, surprisingly, many animals can perceive.

What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

It involves measuring the absorption of light by molecules across a wavelength range from the mid and near UV (200 nm–400 nm) to visible light (400 nm–900 nm). The shape of absorption spectra, ...

Biofluorescence is widespread in birds-of-paradise, a group of tropical birds famous for their spectacular courtship dances.

single monochromator design covering a wavelength range from 190 to 2700 nm (3200 nm option). The monochromator features dual gratings (automatically exchanged): 1200 grooves/mm for the UV/VIS ...

Solar cells are subjected to a lot of harmful ultraviolet light, as they're typically placed for maximum sunlight exposure. A new eco-friendly coating could help protect them from those UV rays, and ...

-Sapphire glass has a large dispersion, which means that light of different wavelengths will experience significant ...
