Su'e/Reflective Neutral Density Filters

Optical density (OD) o lo'o fa'aalia ai le attenuation factor e tu'uina mai e se faamama fa'apitoa, o lona uiga, o le a le tele e fa'aitiitia ai le malosi fa'apitoa o se ave fa'alavelave. OD e fesoʻotaʻi ma le faʻasalalauga. O le filifilia o se faamama ND e maualuga atu le mata'utia o le a fa'aliliuina i lalo ole fa'asalalauga ma sili atu le fa'aogaina ole malamalama fa'alavelave. Mo fa'asalalauga maualuga ma fa'aitiitia le fa'amago, e talafeagai le fa'amaualalo fa'apitoa. Mo se faʻataʻitaʻiga, afai o se faamama e iai le OD o le 2 e maua ai se tau faʻasalalau o le 0.01, o lona uiga o le faamama e faʻaitiitia le uila i le 1% o le malosi faʻafuaseʻi. E lua ituaiga o ND filiters: absorptive neutral density filters, reflective neutral density filters.

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.
