ʻO Steinheil Cemented
ʻAchromatic Triplets

ʻO ke kiko kiko kahi e hui ai nā kukuna māmā i ke kikowaena o ka lens e hui like ʻole mai ke kiko kiko kahi e hui ai nā kukuna māmā e hele ana ma nā ʻaoʻao o ka lens, ua kapa ʻia kēia aberration spherical;i ka wā e hele ai nā kukuna māmā i kahi lens convex, ʻoi aku ka mamao o ke kiko no ke kukui ʻulaʻula nona ka nalu lōʻihi ma mua o ke kiko no ke kukui uliuli nona ka lōʻihi hawewe pōkole, no laila ua ʻike ʻia ke koko o nā kala, ua kapa ʻia kēia chromatic aberration.No ka mea, ʻo ka ʻaoʻao o ka spherical aberration i loko o ka convex lens he kūʻē i ka concave lens, ma o ka hui ʻana o ʻelua a ʻoi aʻe nā lens hiki ke hoʻohuli ʻia nā kukuna māmā i kahi kiko hoʻokahi, ua kapa ʻia kēia ʻano hoʻoponopono aberration.Pololei nā lens Achromatic no nā aberrations chromatic a me spherical.Hoʻolālā ʻia a hana ʻia kā mākou maʻamau a me nā achromats maʻamau e hoʻokō i nā ʻae ʻoi loa i koi ʻia i nā ʻōnaehana laser kiʻekiʻe, electro-optical a me nā ʻōnaehana kiʻi.

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 ka 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. Hana kēia mau lens i nā optic relay maikaʻi no ka hoʻohana ʻana ma luna a me 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.
