Hoʻohana i nā kānana
ʻO ka hoʻohana ʻana i nā kānana ma waena o nā ʻāpana spectral like ʻole i ka ʻoihana optical e hoʻohana nui i kā lākou koho koho lōʻihi, hiki i nā hana kikoʻī ma o ka hoʻololi ʻana i ka lōʻihi nalu, ka ikaika, a me nā waiwai optical ʻē aʻe. Hōʻike kēia i nā hoʻohālikelike mua a me nā hiʻohiʻona noi e pili ana:

Hoʻokaʻawale ma muli o nā hiʻohiʻona spectral:
1. Kānana holo lōʻihi (λ > ka lōʻihi hawewe ʻoki ʻia)
ʻO kēia ʻano kānana e ʻae i nā lōʻihi hawewe i ʻoi aku ma mua o ka lōʻihi o ka hawewe i ʻoki ʻia i ka wā e pale ana i nā nalu pōkole. Hoʻohana maʻamau ia i ka biomedical imaging a me ka lāʻau aesthetics. No ka laʻana, hoʻohana nā microscopes fluorescence i nā kānana lōʻihi e hoʻopau i nā kukui hoʻopilikia i ka nalu pōkole.

2. kānana ala pōkole (λ < ka lōʻihi hawewe ʻoki ʻia)
Hoʻouna kēia kānana i nā lōʻihi hawewe i ʻoi aku ka pōkole ma mua o ka nalu ʻoki ʻia a hoʻemi i nā lōʻihi nalu lōʻihi. Loaʻa iā ia nā noi ma Raman spectroscopy a me ka nānā ʻana i ka astronomical. ʻO kahi hiʻohiʻona kūpono ʻo ka kānana short-pass IR650, i hoʻohana ʻia i nā ʻōnaehana kiaʻi palekana e hoʻopau i ka interference infrared i nā hola o ke ao.

3. Kānana ʻākeʻe (bandwidth < 10 nm)
Hoʻohana ʻia nā kānana Narrowband no ka ʻike pololei ʻana i nā kahua e like me LiDAR a me Raman spectroscopy. No ka laʻana, ʻo ka kānana narrowband BP525 e hōʻike ana i ka nalu waena o 525 nm, kahi ākea piha i ka hapalua kiʻekiʻe (FWHM) o 30 nm wale nō, a me kahi transmittance kiʻekiʻe ma mua o 90%.

4. Notch kānana (stopband bandwidth < 20 nm)
Hoʻonohonoho pono ʻia nā kānana notch no ka hoʻopaʻa ʻana i ke keʻakeʻa i loko o kahi ākea kikoʻī. Hoʻohana nui ʻia lākou i ka pale laser a me ke kiʻi bioluminescence. ʻO kahi laʻana e pili ana i ka hoʻohana ʻana i nā kānana notch e ālai i nā hoʻokuʻu laser 532 nm i hiki ke hoʻopilikia.

Hoʻokaʻawale ma muli o nā hiʻohiʻona hana:
- Nā kiʻiʻoniʻoni polarizing
Hoʻohana ʻia kēia mau ʻāpana e hoʻokaʻawale i ka anisotropy kristal a i ʻole e hoʻemi i ka hoʻopili ʻana i nā kukui ambient. No ka laʻana, hiki i nā polarizer uea metala ke kū i ka irradiation laser kiʻekiʻe a kūpono no ka hoʻohana ʻana i nā ʻōnaehana LiDAR kaʻa kaʻawale.

- Nā aniani Dichroic a me nā mea hoʻokaʻawale kala
Hoʻokaʻawale nā aniani Dichroic i nā kaha kikoʻī kikoʻī me nā ʻaoʻao hoʻololi kiʻekiʻe—no ka laʻana, e hōʻike ana i nā lōʻihi nalu ma lalo o 450 nm. Hāʻawi like nā Spectrophotometers i nā kukui i hoʻouna ʻia a ʻike ʻia, kahi hana i ʻike pinepine ʻia i nā ʻōnaehana kiʻi multispectral.

Nā hiʻohiʻona noiʻi kumu:
- Nā mea lapaʻau: ʻO ka mālama ʻana i ka laser Ophthalmic a me nā mea dermatological pono e hoʻopau i nā kaula spectral pōʻino.
- Ka ʻike maka: Hoʻohana nā microscope fluorescence i nā kānana ʻike no ka ʻike ʻana i nā protein fluorescent kikoʻī, e like me GFP, ma laila e hoʻonui ai i nā lakio hōʻailona-a-leo.
- Ka nānā ʻana i ka palekana: Hoʻonohonoho ka kānana IR-CUT i ka pale ʻana i ka radiation infrared i ka wā o ka hana ʻana i ke ao e hōʻoia i ka hana hou ʻana o ka kala i nā kiʻi i hopu ʻia.
- ʻenehana Laser: Hoʻohana ʻia nā kānana notch no ka hoʻopau ʻana i ka hoʻopilikia ʻana i ka laser, me nā noi e pili ana i nā ʻōnaehana pale kaua a me nā mea ana pono.
