1.71 ʻIke Hoʻokahi HMC Nā lens Optical
1.71 lens Full name 1.71 refractive index lens, me ka kiʻekiʻe refractive index, high transmittance, kiʻekiʻe Abbe helu hiʻohiʻona, i ka hihia o ka like myopia degere, hiki ke hoemi nui i ka mānoanoa o ka lens, hoemi i ka maikai o ka lens, ma ka like. manawa, e hoʻomaʻemaʻe a ʻālohilohi ka lens, ʻaʻole maʻalahi e hoʻopuehu i ka palaoa anuenue. Ua ʻike ʻia ʻo ka hoʻohui ʻana i ka resin cyclic sulfide i loko o ka mea lens hiki ke hoʻomaikaʻi i ka index refractive o ka lens, akā ʻoi aku 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 ke kaohi pono ʻana i ka ʻike o ka resin sulfur ring i ka resin 1.71KR, loaʻa ka lens 1.71 i ka helu refractive kiʻekiʻe a me ka helu abbe ʻoiai e hōʻoiaʻiʻo ana i ka transmittance māmā, haʻahaʻa haʻahaʻa a me ka ʻike maopopo.
