Nā hiʻohiʻona huahana
1. ʻO nā hiʻohiʻona o CR39 Lens:
① ʻO ka monomer CR-39 me ka maikaʻi paʻa a me ka nui o ka hana hana. Hoʻokipa ʻia ia ma ʻEulopa, ʻAmelika Hema a me Asia. Ua kaulana ʻo UC ma ka mākeke akā hāʻawi pū mākou i ka lawelawe HMC a me HC.
ʻOi aku ka maikaʻi o ②CR-39 ma mua o ka Polycarbonate.ʻOi aku ka maikaʻi o ka paʻa ʻana i ka tint ma mua o nā mea lens ʻē aʻe.He mea maikai ia no na makaaniani a me na makaaniani kuhikuhi.
③ʻO nā lens i hana ʻia mai ka monomer CR-39 he pale pale, māmā, ʻoi aku ka liʻiliʻi o ka chromatic aberration ma mua o nā lens polycarbonate, a kū i ka wela a me nā kemika hale a me nā huahana hoʻomaʻemaʻe.
④CR-39 ʻaʻole e pohu e like me nā aniani aniani.ʻOiai ʻo ka wili a i ʻole ka wili ʻana i ka spter e pit a paʻa mau paha i nā aniani aniani, ʻaʻole ia e pili i nā mea aniani plastik.
2. ʻO nā pono o ka helu helu 1.499
①ʻOi aku ka maikaʻi ma waena o nā lens index ʻē aʻe i ka paʻakikī a me ka paʻakikī, ka hopena kiʻekiʻe.
② ʻOi aku ka maʻalahi ma mua o nā lens index ʻē aʻe.
③ ʻO ke kiʻekiʻe o ka transmittance i hoʻohālikelike ʻia me nā lens index ʻē aʻe.
④ʻO ka waiwai ABBE kiʻekiʻe e hāʻawi ana i ka ʻike ʻike ʻoluʻolu loa.
⑤ ʻOi aku ka hilinaʻi a me ka paʻa o ka huahana lens ma ke kino a me ka optically.
⑥ʻO ka mea kaulana loa i nā ʻāina pae waena
3. He aha ka ʻokoʻa ma waena o HC, HMC a me SHC?
| Paʻa paʻa | ʻO ka uhi AR/Ka uhi nui paʻakikī | Ka uhi ʻana o ka super hydrophobic |
| paʻakikī ka lens uncoated a hoʻonui i ka pale abrasion | hoʻonui i ka transmittance o ka lens a hōʻemi i ka noʻonoʻo ʻana o ka ʻili | hana i ka lens i wai ʻole, antistatic, anti slip a me ka ʻaila |
