1.71 Nā aniani ʻike hoʻokahi HMC Optical
1.71 lens Inoa piha 1.71 lens refractive index, me ke kiʻekiʻe o ka refractive index, ka transmittance kiʻekiʻe, nā ʻano helu Abbe kiʻekiʻe, i ke ʻano o ke kekelē myopia like, hiki ke hoʻemi nui i ka mānoanoa o ka lens, hoʻemi i ke ʻano o ka lens, i ka manawa like, e hoʻomaʻemaʻe a ʻālohilohi ka lens, ʻaʻole maʻalahi ka hoʻopuehu ʻana i nā hua anuenue. Ua ʻike ʻia ʻo ka hoʻohui ʻana i ka resin cyclic sulfide i loko o ka mea lens hiki ke hoʻomaikaʻi i ka refractive index o ka lens, akā ʻo ka nui o ka cyclic sulfide resin e alakaʻi i ka hōʻemi ʻana o ka transmittance māmā a me ka haki ʻana o nā mea. Ma ka hoʻomalu pono ʻana i ka ʻike o ka resin sulfur apo i loko o ka resin 1.71KR, loaʻa i ka lens 1.71 ke kiʻekiʻe o ka refractive index a me ka helu abbe me ka hōʻoia ʻana i ka transmittance māmā maikaʻi, ka hoʻopuehu haʻahaʻa a me ka ʻike maopopo.
