Except the glass of KABEr that the spectrum is not found the releasing of the glass. When provide the instance of wave that photob in order to stimulate 379 nanometers. The example of the glass that is stimulated by Photon with 521 nanometers of Length.Then it will give the most of intensity of light by the intensity of spectrum, the light's releasing of the KABEr glass. It will be more valuable than the NABEr and NABE sequentially.
