Hoʻomaka i nā Lenses Polarized

Ke wela ka lewa, nui aʻe ka poʻe e koho e komo i nā makaaniani e pale ai i ko lākou mau maka. Hoʻokaʻawale ʻia nā makaaniani maʻamau i ka tinted a me ka polarized. Inā he mea kūʻai aku a ʻoihana paha, ʻaʻole ʻike ʻia nā aniani polarized.

Wehewehe o ka Polarization
ʻO ka polarization, ʻike ʻia hoʻi he kukui polarized, e pili ana i ka mālamalama ʻike ʻia he hawewe transverse, me kona kuhikuhi haʻalulu e pili pono ana i ke kuhikuhi o ka hoʻolaha ʻana. ʻO ke kuhikuhi haʻalulu o ka mālamalama maoli ke kū ʻole i ka mokulele e kū pono ana i ke kuhikuhi o ka hoʻolaha ʻana; no ka malamalama polarized, ua kaupalena ʻia kona kuhikuhi haʻalulu i kahi kuhikuhi kikoʻī i kekahi manawa.

Hoʻokaʻawale Polarization
Hiki ke hoʻokaʻawale ʻia ka polarization i ʻekolu mau ʻano: linear polarization, elliptical polarization, a me circular polarization. ʻO ka maʻamau, ʻo ka polarization i kapa ʻia e pili ana i ka polarization linear, ʻike ʻia hoʻi ʻo ka polarization plane. Hoʻopaʻa ʻia ka haʻalulu o kēia ʻano o ka nalu māmā ma kahi kuhikuhi kikoʻī a ʻaʻole i loli. ʻO kona ala hoʻolaha ma ke ākea e hahai ana i ka ʻalihi sinusoidal, a ʻo kona kuhi ʻana ma ka mokulele e kū pono ana i ka ʻaoʻao o ka hoʻolaha ʻana he laina pololei.

ʻO ka mokulele i hana ʻia e ka vibration kuhikuhi o ka linearly polarized light a me ke kuhikuhi o ka hoʻolaha ʻana ua kapa ʻia ʻo ka plane of vibration, a ʻo ka mokulele perpendicular to the vibration direction a loaʻa i ke kuhikuhi o ka hoʻolaha ʻana i kapa ʻia ʻo ka plane of polarization. ʻO ka hele ʻana i ka mālamalama maoli ma o ka polarizer hiki ke hana i nā kukui polarized linearly.

Ka Hana o ka Polarization
I ke ola o kēlā me kēia lā, nui nā kumu kukui e hoʻopuka i nā kukui pōʻino, ʻoi aku ka lā. Hoʻopuka ka lā i ʻekolu ʻano kukui: ʻike maka, kukui infrared, a me nā kukui ultraviolet (UV). Ma waena o kēia mau mea, hiki i ke kukui ultraviolet ke hōʻeha nui i ka ʻili a me nā maka. Aia nā kukui ʻike ʻia mai 380 a 780 nanometers, ʻoiai ua māhele ʻia ke kukui ultraviolet i UVA, UVB, a me UVC, me nā hawewe ma luna o 310nm. ʻO UVA, UVB, a me UVC nā kukuna ʻino. ʻO ka loaʻa ʻana i kēia mau kukuna hiki ke hōʻino i ke kino. He hopena koʻikoʻi ko UVB i ka hihiʻo, a ʻo ia hoʻi ka "tanning ray" e pōʻeleʻele ai ka ʻili. ʻO ka hapa nui o nā kihi o ka maka e hoʻopaʻa i kēia ʻano kukui UVB, no laila pono e pale i kēia kumu kukui.

Nā lens polarizedLoaʻa iā lākou ka hana o ke kukui polarizing, kahi e hiki ai iā lākou ke pale i nā kukui ʻino me ka ʻole o ka hoʻopili ʻana i ka hoʻouna ʻana o ka mālamalama ʻike, a laila e pale ai i nā maka. Ma waho aʻe o ka hana maʻamau o ka pale ʻana o UV, loaʻa i nā lens polarized ka anti-glare, ka nānā ʻana i ke alanui, a me nā hana ʻālohilohi o ka wai, e kūpono iā lākou no ka hoʻokele, lawaiʻa, huakaʻi, a me nā lole o kēlā me kēia lā.

Ka Hana ʻana o nā Lenses Polarized
Ma ka ʻōlelo a ka lehulehu,nā lens polarizedNo ka ʻike maka he ʻano like me ka sanwiti (ʻo ia ka papa mua o nā makaaniani, ka papa waena o nā fiber polarized, a me ka papa hope o nā lens ʻike kokoke, ua laminated pū ʻia). He 1.50 ka helu kuhikuhi refractive o ka mea lens maʻamau (he 1.60 kekahi, akā ʻoi aku ke kumukūʻai). He mānoanoa a kaumaha nā lens, a inā ʻoi aku ke kau ʻana ma mua o 600 °, e hoʻopilikia nui ʻia ka aesthetics a me ka hōʻoluʻolu. ʻO ke kumu kūʻai o nā lens polarized no ka ʻike maka he ākea ākea a hilinaʻi i ka paʻa a me ka maikaʻi o ke kaʻina hana.

He mea kōkua nā lens polarized i ka kānana ʻana i nā kukui i hoʻopuehu ʻia (e like me ka hopena grating o nā makapō), akā he ʻokoʻa nui ka maikaʻi. Hiki i nā lens polarized maikaʻi ʻole ke delamination a me ka haki ʻana, a ʻaʻole nui ka poʻe i hoʻokō i nā kūlana optical.
ʻO nā mea o nā Lenses Polarized
ʻEhā ʻano maʻamau onā lens polarizedma ka mākeke: nā aniani aniani, nā lens resin, nā lens PC, a me nā lens TAC.
① Nā aniani aniani
ʻOiai ʻaʻole hiki ke ʻoki ʻia a loaʻa iā lākou ka hana optical maikaʻi, ʻo ko lākou kaumaha a me nā pilikia palekana ua alakaʻi i ka emi mālie o kā lākou hoʻohana.
② Nā leki resin
He maʻalahi lākou i ka ʻoni, māmā, a me ka hopena-kūʻai, e hoʻolilo iā lākou kekahi o nā mea waiwai nui no nā aniani kaulana. Eia nō naʻe, maʻalahi nā lens resin i ka ʻoki ʻana i ka wā o ke kaʻina hana edging, a hiki iā lākou ke waiho i nā pōʻino palekana ke loaʻa i ka hopena koʻikoʻi.
③ Nā leka TAC
ʻO TAC kekahi o nā mea molekala kiʻekiʻe. ʻO nā lens TAC e like me nā makaaniani he mau hiʻohiʻona e like me ke kūpaʻa waika a me ka alkali, māmā, a me ke kumukūʻai kiʻekiʻe. Eia nō naʻe, ʻaʻole maikaʻi ke kūʻē abrasion o nā lens TAC a me nā hiʻohiʻona optical paʻa ʻole. ʻOiai ko lākou kumu kūʻai haʻahaʻa, ua haʻalele ʻia lākou e ka hapa nui o nā hōʻailona haole kaulana.
④ Nā lens PC
He māmā lākou, maikaʻi ka hana ʻoniʻoni, a ʻoi aku ka ikaika o ke kūpaʻa ʻana, ʻo ia hoʻi ke kumu kūʻai nui.
Ua lanakila nā lens PC i ke koʻikoʻi spherical a me nā pilikia astigmatism i hana ʻia e ka deformation o nā lens TAC kuʻuna ma hope o ka hana ʻia. Loaʻa iā lākou ke kūpaʻa hopena ikaika loa (60 mau manawa o nā lens aniani, 20 mau manawa o nā lens TAC, a me 10 mau manawa o nā lens resin) a hoʻohana nui ʻia i ka aerospace a me nā kahua kaua. I ka manawa like, māmā nā lens PC, ʻoi aku ka māmā o 37% ma mua o nā lens resin maʻamau.

Ka Okoa MawaenaNā Leni PolarizedA me nā Lens Tinted
Hoʻohana wale nā ​​lens tinted i ka hana o ka hōʻemi ʻana i ke kukui, ʻaʻole hiki iā lākou ke kānana i ka mālamalama. Hiki iā lākou ke hoʻohaʻahaʻa i ka ikaika o ka ʻālohilohi, ke kukui ultraviolet, a me nā mea ʻē aʻe, a ʻaʻole hiki ke hoʻopaʻa loa i kēia mau kukuna kukui ʻino. I ka manawa like, no ka emi ʻana o ke kukui, pili ia i ka transmittance o nā lens, e waiho ana i kahi pōʻino palekana no nā mea hoʻohana.
