E pili ana ka index lens i ka index of refraction (i ʻike ʻole ʻia ʻo refractive index) o nā mea lens no nā maka maka. He helu ana pili ia e wehewehe ana i ka pono o ka mea e wili ai i ka malamalama. E pili ana ka refraction māmā i ka hele ʻana o ke kukui ponoʻī i loko o ka lens.
Hoʻokaʻawale ʻia nā mea Lens ma kā lākou kuhikuhi kuhikuhi. ʻO kēia ʻōlelo kuhikuhi refractive ka ratio o ka māmā o ka māmā ke hele ʻo ia ma ka ea a me ka wikiwiki o ka māmā ke hele ʻo ia i ka mea lens. He hōʻailona ia o ka nui o ka mālamalama e piʻo i kona hele ʻana ma ka lens. Hoʻopaʻa ʻia ka mālamalama ma ka ʻili mua o ka lens, a laila hoʻi i kona puka ʻana mai ka lens. No laila hiki ke hoʻomaʻamaʻa ʻia ka lens, a maʻalahi hoʻi.

Me nā lens makaaniani maʻamau, ʻoi aku ka lahilahi o ke kikowaena o nā aniani a ʻoi aku ka mānoanoa o nā ʻaoʻao o waho e hoʻomaʻamaʻa i ka refraction ʻo ia ka mea e hana ai nā aniani kuhikuhi! He kiʻekiʻe aʻe ka helu kuhikuhi o ka refraction o nā lens index kiʻekiʻe ma mua o nā lens maʻamau, ʻo ia hoʻi ʻaʻole pono lākou e mānoanoa a puni nā ʻaoʻao i mea e pono ai.
ʻO nā lens-index kiʻekiʻe ke ʻano o ka lens ponoʻī hiki ke ʻoi aku ka lahilahi a me ka māmā. ʻO kēia ka mea e hiki ai i kāu mau aniani ke lilo i mea nani a ʻoluʻolu e like me ka hiki. ʻOi aku ka maikaʻi o nā lens kiʻekiʻe inā loaʻa iā ʻoe kahi ʻōlelo kuhikuhi maka aniani ikaika no ka ʻike kokoke, ʻike maka, a i ʻole astigmatism. Eia nō naʻe, ʻo ka poʻe me ka haʻahaʻa haʻahaʻa maka aniani e hiki ke pōmaikaʻi mai nā lens index kiʻekiʻe.
ʻO 1.71 kahi huahana counterattack. Ma keʻano laulā, ʻoi aku ka kiʻekiʻe o ka helu refractive, ʻoi aku ka haʻahaʻa o ka helu Abbe. ʻO ka helu 1.67 Abbe he 32, ʻo ka 1.74 he 33, a hiki i ka 1.71 ke hana i ka 37. Ua kūleʻa ka hoʻouka kaua. He kiʻekiʻe ka helu Abbe, haʻahaʻa ka hoʻopuehu, ʻoi aku ka maʻalahi. ʻoi aku ka liʻiliʻi o ka 1.67 ma mua o 1.74, akā ʻoi aku ka manoanoa i ke kiʻekiʻe. ʻO 1.74 ka lahilahi, akā he kiʻekiʻe ke kumukūʻai, ʻoi aku ka nui o ka waena waena. Hiki i nā hoa he nui ke koho i ka 1.67 no kā lākou ʻeke. A hoʻopiha ka 1.71 i kēlā āpau.
