1.523 Aniani Bifocal Photochromic Photogrey Optical Lens

ʻO ka wehewehe pōkole:

Ke hoʻonāwaliwali ʻia ka hoʻololi ʻana o ka maka o ke kanaka ma muli o ka makahiki, pono ʻo ia e hoʻoponopono kaʻawale i kāna ʻike no ka ʻike mamao a kokoke.I kēia manawa, pono pinepine ʻo ia e ʻaʻahu i ʻelua mau makaaniani ma kahi kaʻawale, he mea paʻakikī loa.No laila, pono e wili i ʻelua mana refractive like ʻole ma ka lens hoʻokahi e lilo i mau lens ma nā wahi ʻelua.Kapa ʻia ia mau lens he lens bifocal a i ʻole nā ​​aniani bifocal.

ʻAno hui:ʻo ia ka hoʻohui ʻana i ka mea lens me ka helu hoʻopaʻapaʻa kiʻekiʻe i loko o ka ʻāpana concave ma ka pā nui i ka wela kiʻekiʻe, a ʻo ka haʻahaʻa haʻahaʻa o ka papa kuhikuhi.A laila e holo i ka ʻili o ka ʻāpana ʻāpana e hana i ka curvature o ka ʻāpana ʻāpana e kūlike me ka ʻāpana nui.ʻAʻohe manaʻo o ka palena.ʻO ka heluhelu ʻana i ka A e pili ana i ka mana refractive F1 o ka ʻili mua o ke kahua mamao o ka hihiʻo, ka curvature FC o ke arc concave kumu a me ka ratio hui.ʻO ka lākiō hui ʻana he pilina hana ma waena o ka helu kuhikuhipuʻuone o nā mea lens hui pū ʻelua, kahi n e hōʻike ana i ka kuhikuhi kuhikuhi refractive o ke aniani nui (maʻamau ka aniani lei aliʻi) a ʻo ka ns e hōʻike ana i ka kuhikuhina refractive o ka sub-pepa (ke aniani flint) me he waiwai nui, a laila ka ratio hui 'ana k=(n-1)/(nn), pela A=(F1-FC)/k.Hiki ke ʻike ʻia mai ka ʻōlelo ma luna aʻe ma ke kumumanaʻo, hiki ke hoʻololi i ka curvature o mua o ka papa nui, ka concave arc curvature a me ka sub-plate refractive index hiki ke hoʻololi i ka degere kokoke, akā ʻoiaʻiʻo, hiki ke hoʻokō ʻia ma ka hoʻololi ʻana. ka papa kuhikuhi hoʻopaʻapaʻa sub-plate.Hōʻike ka papa 8-2 i ka ʻōlelo kuhikuhi refractive o ke aniani flint sub-sheet i hoʻohana mau ʻia ma ka honua no ka hana ʻana i nā aniani aniani bifocal hoʻohui like ʻole.

Hiʻona Huahana

ʻO kēia ka 1.523 mineral ʻike hoʻokahi a he hakahaka.
1. Paʻa paʻakikī a pale ʻole.
2. Ka waiwai abbe kiʻekiʻe loa.
3. ʻOi aku ka lōʻihi o ke ola ʻana.
4. ʻO ka mea maka nui o ka lens aniani he aniani optical.
5. ʻOi aku ka maikaʻi o nā waiwai optical, ʻaʻole maʻalahi e ʻohi, kiʻekiʻe refractive index.
6. He maikaʻi ka transmittance a me nā waiwai mechanochemical o ka lens aniani, ka helu refractive mau a me nā waiwai paʻa kino a me nā kemika.
