Hoʻolauna i nā aniani polarized

Ke wela ke aniau, nui aʻe ka poʻe e koho e ʻaʻahu i nā aniani maka e pale i ko lākou mau maka. Ua māhele ʻia nā aniani maka maʻamau i nā kala ʻeleʻele a me nā polarized. Inā he mea kūʻai aku a he ʻoihana paha, ʻaʻole ia he mea maʻamau ʻole nā ​​aniani maka polarized.

Ka Wehewehena o ka Polarization
ʻO ka polarization, i ʻike ʻia hoʻi he kukui polarized, e pili ana i ka mālamalama ʻike ʻia he nalu transverse, me kona kuhikuhi haʻalulu e kū pono ana i ke kuhikuhi o ka hoʻolaha ʻana. ʻO ke kuhikuhi haʻalulu o ke kukui kūlohelohe he mea kūpono ʻole ia ma ka mokulele e kū pono ana i ke kuhikuhi o ka hoʻolaha ʻana; no ke kukui polarized, ua kaupalena ʻia kona kuhikuhi haʻalulu i kahi kuhikuhi kikoʻī i kekahi manawa.

Ka Hoʻokaʻawale ʻana o ka Polarization
Hiki ke hoʻokaʻawale ʻia ka polarization i ʻekolu ʻano: ka polarization linear, ka polarization elliptical, a me ka polarization circular. Ma ke ʻano laulā, ʻo ka mea i kapa ʻia ʻo polarization e pili ana i ka polarization linear, i ʻike ʻia hoʻi ʻo ka polarization plane. Hoʻopaʻa ʻia ka haʻalulu o kēia ʻano nalu māmā ma kahi kuhikuhi kikoʻī a noho mau ʻole. Hahai kona ala hoʻolaha ma ka lewa i kahi piʻo sinusoidal, a ʻo kona projection ma ka mokulele perpendicular i ke kuhikuhi o ka hoʻolaha ʻana he laina pololei.

ʻO ka mokulele i hoʻokumu ʻia e ke kuhikuhi haʻalulu o ke kukui polarized linearly a me ke kuhikuhi o ka hoʻolaha ʻana ua kapa ʻia ʻo ka mokulele o ka haʻalulu, a ʻo ka mokulele perpendicular i ke kuhikuhi haʻalulu a loaʻa ke kuhikuhi o ka hoʻolaha ʻana ua kapa ʻia ʻo ka mokulele o ka polarization. ʻO ka hala ʻana o ka mālamalama kūlohelohe ma o kahi polarizer hiki ke hana i ka mālamalama polarized linearly.

Ka Hana o ka Polarization
I ke ola o kēlā me kēia lā, nui nā kumu kukui e hoʻopuka ana i ka mālamalama ʻino, ʻoiai ka lā. Hoʻopuka ka lā i ʻekolu ʻano kukui: ka mālamalama ʻike ʻia, ka mālamalama infrared, a me ke kukui ultraviolet (UV). Ma waena o kēia mau mea, hiki i ka mālamalama ultraviolet ke hōʻeha nui i ka ʻili a me nā maka. Loaʻa ka mālamalama ʻike ʻia mai 380 a 780 nanometers, ʻoiai ua māhele hou ʻia ka mālamalama ultraviolet i UVA, UVB, a me UVC, me nā nalu ma luna o 310nm. He mau kukuna ʻino ka UVA, UVB, a me UVC. ʻO ka lōʻihi o ka hoʻopili ʻana i kēia mau kukuna hiki ke hōʻino i ke kino. He hopena koʻikoʻi ko ka UVB i ka ʻike, a ʻo ia hoʻi ka "kukui tanning" e hoʻopōʻeleʻele i ka ʻili. Hoʻopili ka hapa nui o nā kihi o ka maka i kēia ʻano kukui UVB, no laila he mea nui e ālai i kēia kumu kukui.

Nā aniani polarizedLoaʻa iā lākou ka hana o ke kukui polarizing, kahi e hiki ai iā lākou ke ālai i ka mālamalama ʻino me ka ʻole o ka hoʻopilikia ʻana i ka hoʻoili ʻana o ke kukui ʻike ʻia, a laila e pale ai i nā maka. Ma waho aʻe o ka hana kumu o ka pale ʻana iā UV, loaʻa pū nā aniani polarized i nā hana anti-glare, reflection alanui, a me nā hana glare wai, e kūpono ai no ka hoʻokele kaʻa, ka lawaiʻa, ka huakaʻi, a me ke komo ʻana i kēlā me kēia lā.

Ka Hana ʻana o nā Lens Polarized
Ma ka ʻōlelo maʻamau a ka poʻe maʻamau,nā aniani polarizedno ka ʻike maka kokoke he ʻano sandwich (aia i loko o kahi papa mua o nā aniani maka, kahi papa waena o nā olonā polarized, a me kahi papa hope o nā aniani maka kokoke, i hoʻopaʻa ʻia nā mea a pau). ʻO ka mea aniani i hoʻohana pinepine ʻia he 1.50 ka refractive index (aia kekahi 1.60, akā ʻoi aku ke kumukūʻai). He mānoanoa a kaumaha nā aniani, a inā ʻoi aku ke kauoha ma mua o 600°, e hoʻopilikia nui ʻia ka nani a me ka ʻoluʻolu. He ākea loa ke kumukūʻai o nā aniani polarized no ka ʻike maka kokoke a hilinaʻi ia i ke kūpaʻa a me ka maikaʻi o ka hana a ka mea hana hana.

He kōkua nā aniani polarized i ka kānana ʻana i kekahi mālamalama i hoʻopuehu ʻia (e like me ka hopena grating o nā blinds), akā aia kahi ʻokoʻa koʻikoʻi i ka maikaʻi. ʻO nā aniani polarized maikaʻi ʻole e maʻalahi i ka delamination a me ka haki ʻana, a ʻaʻole nui i kūlike i nā kūlana optical.
Nā Mea Hana o nā Lens Polarized
ʻEhā ʻano maʻamau onā aniani polarizedma ka mākeke: nā aniani aniani, nā aniani resin, nā aniani PC, a me nā aniani TAC.
① Nā aniani aniani
ʻOiai lākou e kū'ē i ke kahakaha a he hana optical maikaʻi ko lākou, ua alakaʻi ko lākou kaumaha a me nā pilikia palekana i ka emi mālie ʻana o kā lākou hoʻohana.
② Nā aniani resin
He maʻalahi lākou e hoʻoluʻu, māmā, a kūpaʻa i ka hopena, e lilo ia i hoʻokahi o nā mea nui no nā aniani maka kaulana. Eia nō naʻe, he maʻalahi nā aniani resin e haki i ka wā o ke kaʻina hana edging, a hiki nō iā lākou ke hoʻopilikia i ka palekana ke kau ʻia ka hopena koʻikoʻi.
③ Nā aniani TAC
ʻO TAC kekahi o nā mea molekala kiʻekiʻe moakaka. Loaʻa i nā aniani TAC e like me nā aniani lā nā hiʻohiʻona e like me ke kūpaʻa ʻana i ka waikawa a me ka alkali, māmā, a me ke kumukūʻai kiʻekiʻe. Eia nō naʻe, ʻaʻole kūpaʻa nā aniani TAC i ka abrasion a me nā ʻano optical paʻa ʻole. ʻOiai ke kumukūʻai haʻahaʻa, ua haʻalele ʻia lākou e ka hapa nui o nā lama haole kaulana.
④ Nā aniani PC
He māmā lākou, he hana hoʻoluʻu maikaʻi, a he ikaika ke kūpaʻa i ka hopena, a ʻo ia hoʻi ke kumu kūʻai nui.
Hoʻopau nā aniani PC i ke koʻikoʻi poepoe a me nā pilikia astigmatism i hoʻokumu ʻia e ka deformation o nā aniani TAC kuʻuna ma hope o ke kiʻi ʻia ʻana. Loaʻa iā lākou ke kūpaʻa hopena ikaika loa (60 manawa o nā aniani aniani, 20 manawa o nā aniani TAC, a me 10 manawa o nā aniani resin) a hoʻohana nui ʻia i nā kahua aerospace a me nā kahua koa. I ka manawa like, he māmā nā aniani PC, he 37% ka māmā ma mua o nā aniani resin maʻamau.

Ka ʻokoʻa ma waenaNā aniani polarizedA me nā aniani kala
Hoʻohana wale nā ​​aniani kala i ka hana o ka hōʻemi ʻana i ka mālamalama, a ʻaʻole hiki iā lākou ke kānana i ka mālamalama. Hiki iā lākou ke hōʻemi wale i ka ikaika o ka ʻālohilohi, ka mālamalama ultraviolet, a me nā mea ʻē aʻe, a ʻaʻole hiki ke pale loa i kēia mau kukuna mālamalama ʻino. I ka manawa like, ma muli o ka emi ʻana o ka mālamalama, hoʻopilikia ia i ka hoʻoili ʻana o nā aniani, e hoʻoweliweli ana i ka palekana no ka poʻe e hoʻohana ana.
