ʻOi aku ka paʻakikī o nā lens aspheric no ka mea ʻaʻole lākou e hahai i kahi ʻāpana o ka pōʻai.ʻO nā lens Aspheric he rotationally symmetric a loaʻa i hoʻokahi a ʻoi aku paha nā ʻili aspheric i ʻokoʻa ke ʻano mai kahi pōʻai.
ʻO ka pōmaikaʻi nui o ia mau lens, ʻo ia ka mea e hōʻemi nui i ka spherical aberration.Hiki ke hoʻololi ʻia ka pōʻai ke hiki ʻole i ka lens ke hoʻohuli i nā kukui e hiki mai ana ma kahi kikoʻī.Ma muli o ke ʻano o ka aspheric irregular surface shape, hiki iā ia ke hoʻohana ʻia i nā nalu he nui o ka mālamalama i ka manawa like, e ʻae ana i nā kukui āpau e kau ʻia ma kahi kikoʻī like, e loaʻa ai nā kiʻi ʻoi aku.
ʻAʻole hiki ke wehewehe ʻia nā lens aspheric a pau, inā convex a concave paha, e ka radius hoʻokahi o ka curvature, i ia manawa ua wehewehe ʻia ko lākou ʻano e ka Sag equation, he ʻano loli, a ʻo "k" e wehewehe i ke ʻano holoʻokoʻa o ka ʻili aspheric.
ʻOiai hāʻawi nā lens aspheric i kekahi mau mea maikaʻi ma mua o nā lens maʻamau, ʻoi aku ka paʻakikī o kā lākou hoʻonohonoho kūʻokoʻa iā lākou i ka hana ʻana, no laila pono nā mea hoʻolālā optical e kaupaona i nā pono hana me ke kumukūʻai kiʻekiʻe.ʻO nā ʻōnaehana optical hou e hoʻohana ana i nā mea aspheric i kā lākou mau hoʻolālā e hiki ke hōʻemi i ka nui o nā lens e pono ai, e ʻae i ka hana ʻana i nā ʻōnaehana māmā, ʻoi aku ka paʻakikī, ʻoiai e mālama mau ana a ʻoi aku ka nui o ka hana o nā ʻōnaehana me ka hoʻohana ʻana i nā mea spherical wale nō.ʻOiai ʻoi aku ka maikaʻi ma mua o nā lens maʻamau, hiki i nā lens aspheric ke lilo i kahi koho maikaʻi a me kahi koho ikaika no nā optics kiʻekiʻe.
Hiki ke hana ʻia nā ʻili Aspheric me ka hoʻohana ʻana i nā ʻano hana like ʻole.Hana ʻia ka ʻili aspheric kumu e ka ʻenehana hoʻoheheʻe injection, hiki ke ʻike i nā ʻano like ʻole o ka aspheric surfaces, ʻoi aku ka nui no nā noi hoʻonaʻauao māmā (mālamalama uila).Pono nā aspheres ʻoi aku ka pololei a me ka paʻakikī i ka hana CNC kaʻawale a me ka polishing.
ʻO nā mea Aspherical, me ke aniani semi-optical a me ka optical glass, a me nā mea plastic e like me polycarbonate, polyurethane a i ʻole silicone.
