Ke koho ʻana i ka lens, e loaʻa iā 1.56, 1.61, 1.67, 1.74 a me nā waiwai ʻē aʻe e koho ai, pili kēia waiwai i ka index refractive o ka lens.
ʻOi aku ka kiʻekiʻe o ka helu kuhikuhi refractive o ka lens, ʻoi aku ka lahilahi o ka lens a ʻoi aku ka paʻakikī o ka lens.ʻOiaʻiʻo, ʻoi aku ka kiʻekiʻe o ka refractive index, ʻoi aku ka maikaʻi o ka maikaʻi, a ʻoi aku ka pipiʻi o ka lens.Inā makemake ʻoe e hoʻohālikelike i nā lens lahilahi loa, ʻaʻole wale me ka index refractive, akā me ka nui o ke kiʻi a me ka mamao o ka haumāna.
No laila, ʻo ka manaʻo, pehea ʻoe e koho ai i ka index refractive o ka lens?
ʻO ka poʻe he nui me nā makaaniani wale nō ka mānoanoa o ka lens, ʻoi aku ka lahilahi o ka maikaʻi, e koho pololei i ka lens me ka index refractive kiʻekiʻe.Akā ʻo ka ʻoiaʻiʻo, ʻaʻole ʻoi aku ka kiʻekiʻe o ka refractive index, e like me nā aniani ponoʻī o ke kanaka e koho i ka pono.
No ke aha ʻaʻole ʻoi aku ka maikaʻi o ke kiʻekiʻe o ka refractive index?
ʻO ka mea mua, he kūpono nā mea a pau, ʻaʻole ʻoi aku ka nui o ke kumukūʻai ʻoi aku ka maikaʻi.
ʻO ka lua, ʻoi aku ka kiʻekiʻe o ka helu refractive, ʻoi aku ka haʻahaʻa o ka helu Abbe.ʻO ke kiʻekiʻe o ka helu Abbe, ʻoi aku ka maopopo o ke kiʻi.ʻO ka haʻahaʻa o ka helu Abbe, ʻoi aku ka maopopo o ke kiʻi.
No laila, ʻōlelo pinepine ʻia e koho i ka index refractive kūpono e like me kā lākou mau degere.
Laulaha.
