Nā Lens Plano-Concave a me ʻelua Concave
Hōʻike huahana
ʻO ka lens plano-concave hoʻokahi ʻili palahalaha a hoʻokahi ʻili ʻāwili i loko, kahi e hoʻokaʻawale ai nā kukuna māmā. Hoʻohana pinepine ʻia kēia mau lens no ka hoʻoponopono ʻana i ka ʻike maka o ka poʻe makapō (myopic), no ka mea e hoʻokaʻawale ka mālamalama i ke komo ʻana i ka maka ma mua o ka hiki ʻana i ka lens, no laila e hiki ai ke nānā pono i ka retina.
Hoʻohana pū ʻia nā lens plano-concave i nā ʻōnaehana optical e like me nā telescopes, microscopes, a me nā mea hana like ʻole e like me ke kiʻi ʻana i nā pahuhopu a me nā lens collimating. Hoʻohana ʻia lākou i ka hoʻonui ʻana i ka beam laser a me nā noi hoʻoheheʻe beam.
Ua like nā lens concave pālua me nā lens plano-concave akā ua ʻae ʻia nā ʻaoʻao ʻelua i loko, e hopena i ka hoʻokaʻawale ʻana i nā kukuna māmā. Hoʻohana ʻia lākou e hoʻolaha a nānā i ka mālamalama i nā noi e like me nā mea optical, ʻōnaehana kiʻi, a me nā ʻōnaehana hoʻomālamalama. Hoʻohana pinepine ʻia lākou i nā mea hoʻonui beam a me nā noi hana hoʻoheheʻe ʻana.
ʻO ka pololei plano-concave a me ʻAlua-concave lens he mau mea nui i hoʻohana ʻia i nā ʻenehana optical like ʻole. ʻIke ʻia kēia mau lens no ko lākou pololei kiʻekiʻe, pololei a me ka maikaʻi. Hoʻohana ʻia lākou i nā noi e like me microscopy, ʻenehana laser a me nā mea lapaʻau. Hoʻolālā ʻia kēia mau lens e kōkua i ka hoʻomaikaʻi ʻana i ka mālamalama o ke kiʻi, ka ʻoi a me ka nānā ʻana.
ʻO nā lens plano-concave pololei he ʻili palahalaha ma kekahi ʻaoʻao a he ʻaoʻao concave ma kekahi ʻaoʻao. Kōkua kēia hoʻolālā i ka hoʻokaʻawale ʻana i ka mālamalama a hoʻohana ʻia e hoʻoponopono a kaulike paha i nā lens maikaʻi i nā ʻōnaehana optical. Hoʻohana pinepine ʻia lākou me nā lens maikaʻi ʻē aʻe i kahi ʻōnaehana kiʻi e hōʻemi i nā aberrations holoʻokoʻa o ka ʻōnaehana.
ʻO nā lens biconcave, ma kekahi ʻaoʻao, he concave ma nā ʻaoʻao ʻelua a ʻike ʻia hoʻi nā lens biconcave. Hoʻohana nui ʻia lākou i nā ʻōnaehana kiʻi e hoʻonui i ka mālamalama a hōʻemi i ka hoʻonui holoʻokoʻa o ka ʻōnaehana. Hoʻohana ʻia lākou e like me nā mea hoʻonui beam a i ʻole nā mea hoʻemi i nā ʻōnaehana optical kahi e koi ʻia ai nā anawaena beam hoʻemi.
Hana ʻia kēia mau lens me ka hoʻohana ʻana i nā mea like ʻole e like me ke aniani, ka plastic a me ka quartz. ʻO nā aniani aniani ka mea maʻamau i hoʻohana ʻia i nā ʻano lens plan-concave a me nā ʻano lens bi-concave. Ua ʻike ʻia lākou no nā optics kiʻekiʻe e hōʻoiaʻiʻo i ka mālamalama kiʻi maikaʻi loa.
I kēia manawa, nui nā mea hana like ʻole e hana ana i nā kiʻekiʻe Precision Plano-Concave a me Double Concave Lenses. Ma Suzhou Jiujon Optics, ua hana ʻia nā lens Precision Plano-Concave a me Double Concave mai ke aniani kiʻekiʻe, nona nā waiwai optical maikaʻi loa. Hoʻopili pololei ʻia nā lens e hōʻoia i ka hoʻokō ʻana i nā kūlana koʻikoʻi koʻikoʻi, a loaʻa iā lākou i nā ʻano nui e hoʻokō i nā pono o nā noi like ʻole.
ʻO ka pololei plano-concave a me ka bi-concave lens he mau mea nui i hoʻohana ʻia i nā ʻano noi like ʻole, me ka microscopy, ʻenehana laser, a me nā mea lapaʻau. He kuleana koʻikoʻi kēia mau lens i ka hoʻomaikaʻi ʻana i ka mālamalama kiʻi, ka māmā a me ka nānā ʻana a ua hana ʻia me ka hoʻohana ʻana i nā mea like ʻole e like me ke aniani a me ka quartz. ʻIke ʻia no ko lākou pololei kiʻekiʻe, pololei, a me ka maikaʻi, kūpono lākou no nā noi e koi ana i nā optics kiʻekiʻe.
