Li-Filters tse sa nkeng lehlakore / tse bonahatsang ho se nke lehlakore
Li-filters tsa rona tsa absorptive neutral density (ND) li fumaneha ka boholo bo fapaneng ka li-optical densities (OD) ho tloha ho 0.1 ho isa ho 8.0.Ho fapana le bo-mphato ba bona ba tšepe, filthara e 'ngoe le e' ngoe ea ND e entsoe ka karolo e ka tlase ea khalase ea Schott e khethiloeng bakeng sa coefficient ea eona ea ho monya e bataletseng sebakeng se bonahalang ho tloha 400 nm ho isa 650 nm.
