In 2016, an Indian-born British artist named Anish Kapoor was given exclusive rights to use Vantablack, the darkest material in the world with an absorption rate of 99.96%. This sparked a furious reaction from fellow artists; some have stated that they have never heard of an artist monopolizing a material, while others stated that this was downright immoral.

Hi, I am Teppei of KoPro! As a feature of our anti-reflection material, "FineShut" series, "absorbing near-infrared" is one of its priding features. First, what is near-infrared in the first place? Humans can visually perceive electromagnetic waves in the wavelength range of 380 to 750 nm. The short wavelength up to 380nm is recognized as violet while the long wavelength up to 750nm is recognized as red. Wavelength range exceeding red 750 nm is called infrared.
