Hastings Sima
Achromatic Triplets

O tioata achromatic o se filifiliga lelei mo le mana'omia o le maualuga o le fa'atonutonuina o le aberration, aua latou te ofoina atu le sili atu le lelei o le fa'atinoga nai lo solo fa'apolofesa. Fa'alua fa'a-achromatic sima e lava lea mo le tele o fa'aoga i fa'atasi e le i'u, ma o ta'i lua fa'asima e fetaui lelei mo fa'aputuga fa'ai'u. Ae ui i lea, o Achromatic triplets e ofoina atu e sili atu le lelei nai lo le achromatic doublets, o le mea moni o le achromatic triplets o le tioata sili ona faigofie e faʻasaʻo uma ai le chromatic aberrations muamua ma faʻaalia lelei le faʻatinoga i luga ma fafo.

O ta'i tolu achromatic o lo'o i ai se elemene pito i lalo o le pale fa'amaufa'ailoga ua fa'amauina i le va o elemene pito i fafo o le maa ma'a maualuga tutusa. O nei ta'i tolu e mafai ona fa'asa'o uma axial ma lateral chromatic aberration, ma o latou mamanu fa'atusa e maua ai le fa'aleleia atili o le fa'atinoga e feso'ota'i ma fa'alua sima.

Hastings achromatic triplets ua mamanuina e maua ai se fua faatatau conjugate e le i'u ma e aoga mo le taulaʻi o ave faʻatasi ma mo le faʻalauteleina. I le Fa'atusatusaga, Steinheil achromatic triplets ua mamanuina e tuʻuina atu se faʻatusatusaga faʻatusatusa ma 1: 1 ata. O le Paralight Optics e ofoina uma Steinheil ma Hastings achromatic triplets faʻatasi ai ma se faʻamalama faʻafefe mo le 400-700 nm galu umi, faʻamolemole siaki le kalafi o loʻo i lalo mo au faʻamatalaga.
