ʻO ka triplets achromatic kahi mea kikowaena lei-index haʻahaʻa i hoʻopaʻa ʻia ma waena o ʻelua mau mea like ʻole kiʻekiʻe-index flint waho. Hiki i kēia mau triplets ke hoʻoponopono i ka axial a me lateral chromatic aberration, a ʻo kā lākou hoʻolālā symmetric e hāʻawi i ka hana i hoʻonui ʻia e pili ana i nā pālua cemented. Hoʻolālā kūikawā ʻia nā ʻekolu Steinheil no ka hui ʻana o 1: 1, hana maikaʻi lākou no nā ratio conjugate a hiki i 5. ʻO kēia mau lens e hana i nā optic relay maikaʻi no ka hoʻohana ʻana ma luna a i waho-axis a hoʻohana pinepine ʻia e like me nā maka maka.
Hāʻawi ʻo Paralight Optics iā Steinheil achromatic triplets me ka MgF2 one layer anti-reflective coatings no ka 400-700 nm hawewe lōʻihi ma nā ʻaoʻao ʻelua o waho, e ʻoluʻolu e nānā i ka pakuhi ma lalo no kāu mau kuhikuhi. ʻO kā mākou hoʻolālā lens i hoʻopaʻa ʻia i ka lolouila e hōʻoia e hōʻemi ʻia nā aberrations chromatic a me spherical i ka manawa like. Ua kūpono nā lens no ka hoʻohana ʻana i ka hapa nui o nā ʻōnaehana kiʻi hoʻonā kiʻekiʻe a me nā noi kahi e hoʻemi ʻia ai nā aberrations spherical a me chromatic.
