Colored glass filters may be obtained by addition of electrically charged ions that are homogeneously distributed, and by precipitation of finely dispersed particles (such as in photochromic glasses). They all have their own spectral transmittance characteristics. They can be uniformly or selective property of optically in specific spectrum regions. They can be classified into many different categories according to their spectrum draft.
