ʻO ka lens aspheric a i ʻole asphere (i kapa pinepine ʻia ʻo ASPH ma nā ʻāpana maka) he lens nona nā ʻaoʻao o ka ʻili he ʻāpana o ka pōʻai a i ʻole ka cylinder.Hiki ke hoʻemi a hoʻopau i ka aberration spherical a hoʻemi i nā aberrations optical ʻē aʻe e like me ka astigmatism, ke hoʻohālikelike ʻia me kahi lens maʻalahi.Hiki i kahi lens aspheric hoʻokahi ke hoʻololi pinepine i kahi ʻōnaehana multi-lens paʻakikī.ʻOi aku ka liʻiliʻi a me ka māmā o ka mīkini hopena, a i kekahi manawa ʻoi aku ka liʻiliʻi ma mua o ka hoʻolālā multi-lens.Hoʻohana ʻia nā mea Aspheric i ka hoʻolālā ʻana o nā lens ākea ākea ākea a wikiwiki hoʻi e hōʻemi i nā aberrations.Hoʻohana pū ʻia lākou me nā mea hoʻohālikelike (nā ʻōnaehana catadioptric) e like me ka aspherical Schmidt corrector plate i hoʻohana ʻia i nā kāmela Schmidt a me nā telescopes Schmidt-Cassegrain.Hoʻohana pinepine ʻia nā aspheres liʻiliʻi no ka collimating diode lasers.Hoʻohana ʻia nā lens Aspheric no nā aniani.Hiki i nā lens makaaniani Aspheric ke ʻike ʻoi aku ka maikaʻi ma mua o nā lens "ʻoi aku ka maikaʻi" maʻamau, ʻo ka hapa nui ke nānā aku i nā ʻaoʻao ʻē aʻe ma mua o ke kikowaena optical lens.Eia kekahi, hiki ke kōkua i ka hoʻemi ʻana i ka hopena hoʻonui o ka lens me nā ʻōlelo kuhikuhi i loaʻa nā mana like ʻole i nā maka 2 (anisometropia).ʻAʻole pili i ka maikaʻi optical, hiki iā lākou ke hāʻawi i kahi aniani ʻoi aku ka lahilahi, a hoʻololi i nā maka o ka mea nānā i ʻike ʻole ʻia e nā poʻe ʻē aʻe, e hana ana i kahi hiʻohiʻona nani.
2. Nā lens spherical vs aspherical

Hoʻohana nā lens spectacle Aspherical i nā pihi ʻokoʻa ma luna o ko lākou ʻili e hōʻemi i ka nui a hoʻomāliʻi iā lākou i kā lākou ʻaoʻao.Hoʻohana nā lens spherical i kahi pihi hoʻokahi i kā lākou ʻaoʻao, e maʻalahi iā lākou akā ʻoi aku ka nui, ʻoi aku ka waena o ka lens.
3.Aspheric Pōmaikaʻi
Malia paha ʻo ka ʻoiaʻiʻo ikaika loa e pili ana i ka asphericity ʻo ia ka ʻike ma o nā lens aspheric kokoke i ka ʻike kūlohelohe.Hiki i ka hoʻolālā Aspheric ke hoʻohana i nā pihi kumu paʻa me ka ʻole o ka hoʻokō ʻana i ka hana optical.ʻO ka ʻokoʻa ma waena o ka lens spherical a me ka lens aspheric, ʻo ia ka lens spherical i hoʻokahi curvature a ua ʻano like ia me ka basketball.E neʻe mālie ka lens aspheric, e like me ka pôpeku ma lalo.Hoʻemi ka lens aspheric i ka hoʻonui ʻana i ke ʻano kūlohelohe a ʻo ka emi ʻana o ka mānoanoa waena e hoʻohana i nā mea liʻiliʻi, e hopena i ka liʻiliʻi o ke kaumaha.
