He kiʻekiʻe a haʻahaʻa paha ka transmittance lens?
E pili ana i ka ratio o ka huina o ka malamalama e komo ana i ka maka ma o ka lens i ka huina o ka malamalama i hiki aku i ka lens.ʻOi aku ka kiʻekiʻe o ka ratio, ʻoi aku ka maikaʻi o ka hoʻouna ʻana i ka māmā a ʻoi aku ka kiʻekiʻe o ka wehewehe.
Ma keʻano laulā, nā lens optical me ka multi-layer anti-reflection film, nā lens optical kala ʻole a me nā lens optical ultra-thin aspherical i loaʻa i ka transmittance māmā maikaʻi, a hiki i 99%.Ma kēiaʻano,ʻaʻole hiki i ka mea hoʻohana keʻike i ka maopopo wale nō, akā, e hoʻomaikaʻi nui i kaʻokoʻa hiʻohiʻona a hoʻemi i ka luhi maka.

Pehea e hoʻomalu ai i ka mānoanoa a me ke kaumaha o ka lens?
ʻO ka mānoanoa o ka lens pili i ke kiʻekiʻe o ka diopter, refractive index o ka lens a me ke ʻano a me ka nui o ke kiʻi, no laila ke koho ʻana i ka mānoanoa o ka lens, pono ʻoe e nānā i kāu degere myopia.Inā ʻoi aku ka kiʻekiʻe o ke degere, e koho maikaʻi i ka lens index refractive kiʻekiʻe, no laila ʻoi aku ka lahilahi o ka mānoanoa o ka lens, hiki ke hoʻemi nui i ke kaomi ma ke alahaka o ka ihu.
Eia kekahi, ʻo ke kaumaha o ka lens, i ka wā e pili ana i ke kaumaha, ʻoiaʻiʻo ʻaʻole pili i ka mea o ka lens, ʻo ka mea lens ma ka mākeke ma ke aniani, resin a me PC, ʻoi aku ka nui o ka lens, ʻo ka lens PC ka māmā. , no laila i ke koho ʻana, pono e noʻonoʻo ʻia ka mānoanoa a me ke kaumaha o ka lens.
