Nā Lens Cylindrical

He ʻokoʻa nā radii o nā lens cylindrical i nā koʻi x a me y, ua like lākou me nā lens spherical ma ke ʻano e hoʻohana ai lākou i nā ʻaoʻao curved e hoʻohuli a hoʻokaʻawale paha i ka mālamalama, akā ʻo nā lens cylinder he mana optical i hoʻokahi ʻāpana a ʻaʻole e hoʻopilikia i ka mālamalama i ka perpendicular. anana.Loaʻa i nā Lenses Cylinder kahi ʻili cylindrical hoʻokahi e hoʻohuli ai i ka mālamalama e hiki mai ana i ka nui hoʻokahi wale nō, ʻo ia hoʻi, i loko o kahi laina ma mua o kahi kiko, a i ʻole e hoʻololi i ka lākiō hiʻohiʻona i kahi kiʻi i hoʻokahi axis wale nō.Loaʻa i nā lens cylindrical nā ʻano huinahā, pōʻai, a i ʻole ʻāpana ʻāpana, e like me nā lens spherical, loaʻa pū me nā lōʻihi kūpono a maikaʻi ʻole paha.Hoʻohana pinepine ʻia nā lens cylindrical e hoʻoponopono i ka nui kiʻekiʻe o ke kiʻi, a i ʻole pololei no ka astigmatism i nā ʻōnaehana kiʻi, a ma kahi ākea o nā noi laser me ka circularizing elliptical beams mai kahi laser diode, e kālele ana i kahi kukuna diverging ma luna o kahi laina ʻike laina, e hana ana i kahi pepa kukui. no nā ʻōnaehana ana, a i ʻole ke kuhi ʻana i kahi laina laser ma luna o kahi ʻili.Hoʻohana ʻia nā lens cylindrical i kahi ākea o nā ʻoihana e like me ke kukui detector, bar code scanning, spectroscopy, holographic lighting, optical information processing and computer technology.
