Hoʻohana maʻamau ʻia nā kānana Optical i nā kānana optical, ʻo ia nā mea hana e hoʻouna i nā kukui o nā lōʻihi hawewe like ʻole, maʻamau i nā aniani pālahalaha a i ʻole nā mea plastik i ke ala ʻike, i hoʻoluʻu ʻia a i ʻole nā pale keakea.Wahi a nā hiʻohiʻona spectral, ua māhele ʻia i ka kānana pass-band a me ka kānana ʻoki ʻoki;ma spectral kālailai, ua mahele ia i loko o absorption kānana a me interference kānana.
1. Hana ʻia ka kānana pale ma ka hui ʻana i nā mea pena kūikawā i ka resin a i ʻole nā mea aniani.E like me ka hiki ke komo i ka malamalama o nā nalu like ʻole, hiki iā ia ke pāʻani i kahi hopena kānana.Ua kaulana nā kānana aniani kala i ka mākeke, a ʻo kā lākou mau mea maikaʻi he kūpaʻa, kūlike, ka maikaʻi o ka beam maikaʻi, a me nā kumukūʻai haʻahaʻa haʻahaʻa, akā loaʻa iā lākou ka hemahema o kahi passband nui, ma lalo o 30nm.o.
2. Nā kānana keakea Bandpass
Hoʻohana ia i ke ʻano o ka uhi ʻana i ka vacuum, a hoʻopaʻa i kahi ʻāpana o ke kiʻi ʻoniʻoni me kahi mānoanoa kikoʻī ma ka ʻili o ke aniani.ʻO ka mea maʻamau, hana ʻia kahi ʻāpana aniani ma ke kau ʻana i nā ʻāpana he nui o nā kiʻiʻoniʻoni, a ua hoʻohana ʻia ka loina interference e ʻae i nā nalu māmā e hele i loko o kahi kikoʻī kikoʻī.Nui nā ʻano kānana hoʻopilikia, a ʻokoʻa hoʻi kā lākou mau kahua noi.Ma waena o lākou, ʻo nā kānana interference i hoʻohana nui ʻia ʻo nā kānana bandpass, nā kānana cutoff, a me nā kānana dichroic.
(1) Hiki i nā kānana Bandpass ke hoʻouna wale i nā kukui o kahi hawewe kikoʻī a i ʻole ke kāʻei haiki, a ʻaʻole hiki ke hele aku ke kukui ma waho o ka passband.ʻO nā hōʻailona optical nui o ka kānana bandpass: ka lōʻihi hawewe waena (CWL) a me ka hapalua bandwidth (FWHM).E like me ka nui o ka bandwidth, ua mahele ʻia i: kahi kānana liʻiliʻi me kahi bandwidth<30nm;he kānana broadband me ka bandwidth>60nm.
(2) Hiki i ka kānana ʻoki ʻoki ke hoʻokaʻawale i ka spectrum i ʻelua mau ʻāpana, ʻaʻole hiki i ke kukui ma kahi ʻāpana ke hele i kēia ʻāina i kapa ʻia ʻo ka ʻāpana ʻoki ʻia, a ʻo ke kukui ma kēlā ʻaoʻao hiki ke hele piha i kapa ʻia ʻo ka passband region, ʻO nā kānana ʻokiʻoki maʻamau he mau kānana holo lōʻihi a me nā kānana pōkole pōkole.ʻO kāna kānana wavepass lōʻihi o ke kukui laser: ʻO ia ke ʻano ma kahi kikoʻī o ka hawewe nalu, ua hoʻouna ʻia ka ʻaoʻao o ka nalu lōʻihi, a ua ʻoki ʻia ke ala hawewe pōkole, kahi e hoʻokaʻawale ai i ka nalu pōkole.Ke kānana hele hawewe pōkole: ʻO kahi kānana hawewe pōkole e pili ana i kahi laulā hawewe kikoʻī, hoʻouna ʻia ke ala hawewe pōkole, a ʻoki ʻia ka ʻaoʻao nalu lōʻihi, ʻo ia ke kuleana o ka hoʻokaʻawale ʻana i ka nalu lōʻihi.
3. kānana Dichroic
Hoʻohana ka kānana Dichroic i ke kumu o ke keakea.Hoʻokumu ko lākou mau papa i kahi pūʻulu mau o nā lua hoʻomanaʻo e ʻoluʻolu me ka lōʻihi o ka nalu i makemake ʻia.Ke hili ʻia nā piko a me nā ʻauwai, hoʻopau ʻia a ʻike ʻia paha nā lōʻihi nalu ʻē aʻe.Hiki ke hana ʻia nā kānana Dichroic (i ʻike ʻia ʻo "reflective" a i ʻole "thin film" a i ʻole "interference" kānana) ma o ka uhi ʻana i kahi substrate aniani me ke ʻano o nā ʻāpana optical.Hōʻike pinepine nā kānana Dichroic i nā ʻāpana kukui i makemake ʻole ʻia a hoʻouna i ke koena.
Hiki ke hoʻomaluʻia ka laulā kala o nā kānana dichroic e ka mānoanoa a me ka hoʻonohonoho o nā uhi.ʻOi aku ke kumukūʻai a ʻoi aku ka maʻalahi ma mua o nā kānana absorption.Hiki ke hoʻohana ʻia i nā mea hana e like me nā prisms dichroic i nā kiʻi paʻi kiʻi e hoʻokaʻawale i nā kukui kukui i nā ʻāpana o nā kala like ʻole.
