Tšebeliso ea li-filters
Ts'ebeliso ea li-filters ho pholletsa le lihlopha tse fapaneng tsa spectral indastering ea optical haholo-holo e phahamisa bokhoni ba bona ba ho khetha leqhubu la maqhubu, e nolofalletsang lits'ebetso tse ikhethileng ka ho fetola bolelele ba maqhubu, matla le lisebelisoa tse ling tsa mahlo. Lintlha tse latelang li kenyelletsa likarolo tsa mantlha le maemo a tšoanang a ts'ebeliso:

Sehlopha se ipapisitse le litšobotsi tsa spectral:
1. Sesefa sa nako e telele ( λ > cut-off wavelength)
Sesefe sa mofuta ona se lumella maqhubu a malelele ho feta bolelele ba maqhubu a khaotsoeng ho feta ha a ntse a thibela maqhubu a makhutšoane. E sebelisoa hangata litšoantšong tsa biomedical le aesthetics ea bongaka. Ka mohlala, li-microscopes tsa fluorescence li sebelisa li-filters tsa nako e telele ho tlosa khanya e sitisang leqhubu le lekhutšoanyane.

2. Short-pass filter (λ < cut-off wavelength)
Sefefo sena se fetisa bolelele ba maqhubu a makhutšoane ho feta bolelele bo khaotsoeng, 'me se fokotsa maqhubu a malelele. E fumana lits'ebetso ho Raman spectroscopy le tlhahlobo ea linaleli. Mohlala o sebetsang ke IR650-short-pass filter, e sebelisoang lits'ebetsong tsa ts'ireletso ho thibela tšitiso ea infrared nakong ea motšehare.

3. Setlhopha sa Narrowband (bandwidth <10 nm)
Li-filters tsa Narrowband li sebelisoa bakeng sa ho lemoha ka nepo masimong a kang LiDAR le Raman spectroscopy. Mohlala, filthara ea BP525 narrowband e na le leqhubu le bohareng la 525 nm, bophara bo felletseng ka halofo ea boholo (FWHM) ea 30 nm feela, le phetisetso e phahameng e fetang 90%.

4. Setlhopha sa notch (stopband bandwidth <20 nm)
Li-filters tsa Notch li etselitsoe ho hatella tšitiso ka har'a mefuta e moqotetsane ea spectral. Li sebelisoa haholo ts'ireletso ea laser le litšoantšo tsa bioluminescence. Mohlala o kenyelletsa ts'ebeliso ea li-notch filters ho thibela mesi ea laser ea 532 nm e ka bakang likotsi.

Sehlopha se ipapisitse le litšobotsi tsa ts'ebetso:
- Lifilimi tsa polarizing
Likarolo tsena li sebelisetsoa ho khetholla kristale anisotropy kapa ho fokotsa tšitiso ea leseli le teng. Mohlala, li-polarizer tsa mehala ea tšepe li ka mamella mabone a laser a matla a phahameng 'me li loketse ho sebelisoa lits'ebetsong tsa LiDAR tse ikemetseng.

- Liipone tsa Dichroic le likarohano tsa mebala
Liipone tsa Dichroic li arola lihlopha tse ikhethang tse nang le meepa ea phetoho-mohlala, li bonts'a maqhubu a tlase ho 450 nm. Li-Spectrophotometers li tsamaisa ka ho lekana leseli le fetisoang le le bonts'itsoeng, ts'ebetso e bonoang khafetsa lits'ebetsong tsa litšoantšo tse ngata.

Maemo a mantlha a ts'ebeliso:
- Lisebelisoa tsa bongaka: Kalafo ea laser ea mahlo le lisebelisoa tsa dermatological li hloka ho felisoa ha lihlopha tse kotsi tsa spectral.
- Kutlo ea mahlo: Li-microscopes tsa Fluorescence li sebelisa li-filters tsa mahlo ho bona liprotheine tse khethehileng tsa fluorescent, tse kang GFP, kahoo li matlafatsa likarohano tsa lerata le lerata.
- Tlhokomelo ea ts'ireletso: Filter ea IR-CUT e thibela mahlaseli a infrared nakong ea ts'ebetso ea mots'eare ho netefatsa tlhahiso e nepahetseng ea mebala litšoantšong tse hapiloeng.
- Theknoloji ea Laser: Li-filters tsa Notch li sebelisoa ho hatella tšitiso ea laser, ka lits'ebetso tse akaretsang lits'ireletso tsa sesole le lisebelisoa tsa ho metha ka nepo.
