O a matou filiga fa'a'au'au fa'ato'aga (ND) o lo'o avanoa i lapopo'a eseese fa'atasi ma densities opitika (OD) mai le 0.1 i le 8.0. E le pei o latou faʻataʻitaʻiga, paʻu uʻamea, o ND faamama taʻitasi e faʻapipiʻiina mai se mea faʻapipiʻi o le tioata Schott lea na filifilia mo lona faʻaogaina faʻapitoa faʻapitoa i le itulagi vaʻaia mai le 400 nm i le 650 nm.
O lo'o maua ni fa'amama fa'a'ese'ese fa'afoliga fa'atasi ma le N-BK7 (CDGM H-K9L), UV Fused Silica (JGS 1), po'o le Zinc Selenide substrate i va'aiga eseese. N-BK7 (CDGM H-K9L) filiga e aofia ai se substrate tioata N-BK7 ma le u'amea (Inconel) faʻapipiʻi teuina i le tasi itu, Inconel o se uʻamea uʻamea e mautinoa tali spectral mafolafola mai le UV i le latalata IR; UV fused silica filiga e aofia ai le UVFS substrate ma le nickel coating teuina i le tasi itu, lea e maua ai se tali mata'itusi laugatasi; ZnSe neutral density filiga e aofia ai le ZnSe substrate (optic densities mai le 0.3 i le 3.0) faatasi ai ma le nickel coating i le tasi itu, lea e tau atu i se tali mataʻutia i luga o le 2 i le 16 µm galu umi, faʻamolemole tagaʻi i le kalafi o loʻo i lalo mo au faʻamatalaga.
