ʻO nā mea nui ʻekolu o nā lens optical: he aha nā ʻokoʻa kikoʻī a me nā pono a me nā hemahema o nā lens optical kaulana ʻekolu.ʻO nā aniani kūpono o ka ʻike lens, ua hoʻolauna mākou i ke ʻano o ka hana o ka lens, ua hala iki ke ʻano o ka mea, i kēia manawa ke nānā aku nei mākou i nā mea nui ʻekolu o ka lens: aniani lens / resin lens / PC lens.
ʻEkolu mea hoʻohālike
Nā aniani aniani
I nā lā mua, ʻo ka mea nui no nā lens he aniani optical.ʻO ka mea nui kēia ma muli o ka noʻonoʻo ʻana i ka transmittance kiʻekiʻe a me ka maopopo o nā lens aniani optical, ʻoi aku ka ʻenehana a maʻalahi.Eia nō naʻe, ʻo ka pilikia nui o nā aniani aniani ka palekana, ʻilihune kona hopena ʻino, maʻalahi loa ka haki ʻana, a ma muli o kāna mea kaumaha, ʻaʻole ʻoluʻolu ke ʻaʻahu, no laila ʻaʻole i hoʻohana ʻia ma ka mākeke i kēia manawa.
ʻO nā lens resin
ʻO Resin lens kahi ʻano lens optical i hana ʻia me ka resin ma ke ʻano he mea maka, hana ʻia, synthesized a hoʻoliʻi ʻia e ke kaʻina kemika pololei.I kēia manawa, ʻo ka lens resin ka mea i hoʻohana nui ʻia.ʻOi aku ka māmā o ke kaumaha o ka lens resin ma mua o ka lens aniani optical, a ʻoi aku ka ikaika o ke kūpaʻa hopena ma mua o ke aniani, a ʻaʻole maʻalahi ka haki ʻana, no laila ʻoi aku ka palekana o ka hoʻohana.Ma ke kumu kūʻai, ʻoi aku ka maʻalahi o nā lens resin.Akā ʻilihune ka pale ʻana o ka lens resin, wikiwiki ka wikiwiki o ka oxidation, ʻoi aku ka maʻalahi o ka ʻili o ka lens.
ʻO nā lens PC
ʻO ka lens PC kahi ʻano lens i hana ʻia me ka polycarbonate (thermoplastic material) ma hope o ka hoʻomehana ʻana a me ke ʻano.Ua hoʻomohala ʻia kēia ʻano mea mai ka papahana lewa, no laila ua kapa ʻia ʻo ia ke kiʻi ʻoniʻoni a i ʻole ke kiʻi ʻoniʻoni.ʻO ka resin PC kahi ʻano mea thermoplastic me ka hana maikaʻi, no laila ʻoi aku ka maikaʻi o ka hana ʻana i nā aniani.He maikaʻi loa ka pale ʻana o ka lens PC, ʻaneʻane ʻaʻole haki, palekana kiʻekiʻe.Ma ke ʻano o ke kaumaha, ʻoi aku ka māmā ma mua o nā lens resin.Akā paʻakikī ka lens PC i ka hana ʻana, no laila ke kiʻekiʻe ke kumukūʻai.
E hōʻuluʻulu:
| Mea waiwai | Pōmaikaʻi | Ka pōkole |
| Maka aniani | ʻO ka transmittance kiʻekiʻe a me ka refractive index, ʻaʻahu kūʻē | Kaumaha a maʻalahi hoʻi e haki |
| Leni resin | Māmā, ʻaʻole hiki ke haki, haʻahaʻa ke kumu kūʻai | He ma'alahi ke 'ohi |
| Leni PC | Māmā a haki ʻole | Maʻalahi e ʻohi a kiʻekiʻe ke kumu kūʻai |
Mea kūpono no ka poʻe ʻelemakule
Manaʻo ka poʻe kahiko presbyopia e koho i nā aniani aniani a i ʻole nā lens resin.ʻO ka maʻamau, ʻo ka presbyopia he kiʻi hyperopia haʻahaʻa haʻahaʻa, ʻaʻole koi i ke kaumaha o ka lens kiʻekiʻe, a ʻaʻole kiʻekiʻe ka coefficient neʻe o ka poʻe ʻelemakule.ʻOi aku ke kūpaʻa o ke aniani a i ʻole ke kiʻi ʻoniʻoni resin paʻakikī i nā ʻōpala, a hiki ke paʻa ka hana optical.
Mea kūpono no nā mākua
He kūpono nā lens resin no ka poʻe ʻōpio a me waena.He ākea ka koho o ka lens resin, e like me ka ʻokoʻa o ka refractive index, ka ʻokoʻa hana, ka ʻokoʻa refractive focus, hiki ke hoʻokō i nā pono like ʻole o nā poʻe like ʻole.
Mea kūpono no nā keiki a me nā ʻōpio
Paipai ʻia nā mākua e koho i nā lens i hana ʻia me nā papa PC a i ʻole nā mea Trivex.Ke hoʻohālikelike ʻia me nā lens ʻē aʻe, ʻaʻole māmā wale kēia mau lens i ke kaumaha, akā ʻoi aku ka maikaʻi o ka hopena a me ka palekana kiʻekiʻe.ʻAʻole ʻo ia wale nō, pale pū nā papa PC a me nā lens Trivex i kou mau maka mai nā kukuna UV.
ʻO kēia ʻano lens he paʻakikī ikaika a ʻaʻole maʻalahi e haki, no laila ua kapa ʻia ʻo ia ka lens palekana.Ma ka 2 grams wale no ke kenimika cubic, ʻo ia ka mea māmā loa i loaʻa no nā lens.ʻAʻole kūpono nā aniani no nā keiki i nā aniani aniani, no ka mea, ʻeleʻele nā keiki, a palupalu nā aniani aniani, inā haki, ʻeha nā maka.
Kākau hope
He ʻokoʻa loa nā hiʻohiʻona huahana o nā lens o nā mea like ʻole.He kaumaha ka pepa aniani a he haʻahaʻa haʻahaʻa koʻikoʻi kona kumu palekana, akā kūpaʻa ia i ka ʻōpala a he lōʻihi kona hoʻohana ʻana.He kūpono ia no ka poʻe ʻelemakule me ka liʻiliʻi o ka hoʻoikaika kino a me ka presbyopia haʻahaʻa haʻahaʻa.Loaʻa i ka lens Resin nā ʻano hana like ʻole, kūpono i ka poʻe ʻōpio i nā ʻano aʻo a me nā pono hana;ʻO ka palekana lens o nā keiki, he kiʻekiʻe nā koi portability, ʻoi aku ka maikaʻi o ka lens PC.
