Yakasiyana-siyana Mafirita Marudzi uye Makiyi Mataurirwo

Muchidimbu, mafirita emaziso anogona kukamurwa kuva marudzi akati wandei, uye aya marudzi akasiyana emafirita emeso anounzwa pazasi.

1. Absorption sefa: Iyo yekunyudza sefa inogadzirwa nekusanganisa madhayi akakosha mu resin kana girazi zvinhu.Zvinoenderana nekugona kutora mwenje wewavelengths akasiyana, inogona kuita basa rekusefa.Mafirita egirazi ane mavara ndiwo anonyanya kushandiswa pamusika.Zvakanakira zvaro zvakagadzikana, yunifomu, yakanaka danda mhando, uye yakaderera mutengo wekugadzira, asi ine dhizaini yepassband yakakura, iyo isingawanzo kudzika kupfuura 30nm.

2. Sefa yekukanganisa: Sefa yekukanganisa inotora nzira yekuputira vacuum, uye dhizaini yefirimu yemaziso ine ukomba hwakati yakaputirwa pamusoro pegirazi.Kazhinji chimedu chegirazi chinogadzirwa nemafirimu akawanda-layer, uye musimboti wekukanganisa unoshandiswa kuwana Inobvumira masaisai emwenje mune yakatarwa spectral renji kuti ipfuure.Kune akawanda marudzi ekukanganisa mafirita, uye minda yavo yekushandisa yakasiyanawo.Pakati pavo, anonyanya kushandiswa kupindira mafirita mabhendi mafirita, akachekwa-kubvisa mafirita, uye dichroic mafirita.

(1) Bandpass Mafirita anogona chete kufambisa mwenje weimwe wavelength kana nhete bhendi, uye mwenje kunze kwepassband haugone kupfuura.Iwo main optical zviratidzo zvebhendi mafirita ndeaya: central wavelength (CWL), hafu bandwidth (FWHM), uye transmittance (T%).Zvinoenderana nehukuru hweiyo bandwidth, inogona kukamurwa kuita yakamanikana-bhendi mafirita ane bandwidth isingasviki 30nm;Broadband mafirita ane bandwidth inopfuura 60nm.

(2) Cut-off filter (Cut-off filter) inogona kupatsanura spectrum kuita matunhu maviri.Chiedza chiri mune imwe dunhu hachigoni kupfuura nenharaunda iyi, iyo inonzi nharaunda yakachekwa, nepo chiedza chiri mune imwe dunhu chinogona kunyatsopfuura nemo, icho chinonzi pass-band region.Masefa akajairika mafirita marefu-kupfuura uye mafirita mapfupi.Yakareba-wave pass sefa: inoreva kune yakatarwa wavelength renji, iyo yakareba-wave nzira inofambiswa, uye pfupi-wave nzira inotemwa-yakatemwa, iyo inotora basa rekuparadzanisa mapfupi-wave.Short-wave pass filter: Ipfupi-wave pass sefa inoreva yakananga wavelength renji, iyo pfupi-wave nzira inofambiswa, uye iyo yakareba-wave nzira inodimburwa, iyo inotora basa rekuparadzanisa refu-wave.

(3) Dichroic sefa (Dichroic sefa) inogona kusarudza diki diki yemavara inoda kupfuudza chiedza maererano nezvinodiwa, uye kuratidza mamwe mavara.Kune mamwe marudzi emafirita: Neutral Density Filters (Neutral Density Filters), anozivikanwawo semafirimu ekuderedza, anoshandiswa kudzivirira masosi emwenje akasimba kubva pakukuvadza sensor yekamera kana maoptical components, uye anogona kutora kana kuratidza chiedza chisina kubatwa. .Chikamu chechiedza chinopfuudzwa icho chakafanana chinoderedza kutapurirana mune chimwe chikamu che spectrum.

Basa guru reFluorescence Mafirita nderekuparadzanisa uye kusarudza hunhu bhendi spectra yechiedza chekusimudzira uye inoburitsa fluorescence yezvinhu mubiomedical fluorescence inspection and analysis system.Icho chinhu chakakosha chinoshandiswa mune biomedical uye hupenyu sainzi zviridzwa.

Astronomy Mafirita imhando yefirita inoshandiswa kuderedza kusvibiswa kwechiedza pamhando yemifananidzo panguva yekutora mafoto enyeredzi.

Neutral density mafirita anowanzo kupatsanurwa kuita absorptive uye anoratidza.Iyo reflective neutral density sefa inotora musimboti wekukanganisika kwefirimu diki kuendesa chikamu chechiedza uye kuratidza chimwe chikamu chechiedza (kazhinji hachichashandisi mwenje unotaridzwa), izvi zvinoratidzwa mwenje zviri nyore kugadzira mwenje unorasika uye kuderedza kuedza kwechokwadi. , saka Ndapota shandisa ABC series light collector kuunganidza chiedza chinoratidzwa.Absorptive neutral density mafirita anowanzo tarisa kune icho chinhu pachacho kana mushure mekunge zvimwe zvinhu zvasanganiswa muchinhu, izvo zvinotora mamwe mafungu akareba echiedza, asi zvisina kana zvishoma zvinokanganisa mamwe mafungu echiedza.Kazhinji, chikumbaridzo chekukuvadza chekutora kusarerekera density mafirita yakadzikira, uye mushure mekushandiswa kwenguva refu, panogona kunge paine kupisa kwekupisa, saka kutarisirwa kunofanirwa kutorwa kana uchiashandisa.

Madiro Akakosha eOptical Filters

Passband: Huwandu hwemasaisai ayo chiedza chinogona kupfuura nemauri hunonzi passband.

Bandwidth (FWHM): Bandwidth iwavelength renji rinoshandiswa kumiririra chakananga chikamu cheiyo spectrum inopfuura nepasefa kuburikidza nechiitiko simba, rinoratidzwa nehupamhi pahafu yekupfuura kukuru, inozivikanwawo sehafu yehupamhi, munm.Semuenzaniso: iyo peak transmittance yesefa i80%, ipapo 1/2 i40%, uye kuruboshwe nekurudyi wavelengths inoenderana ne40% i700nm uye 750nm, uye hafu bandwidth i50nm.Avo vane hafu-upamhi isingasviki 20nm vanonzi mafirita-bhendi, uye avo vane hafu-upamhi yakakura kupfuura 20nm vanonzi bhendi-pass mafirita kana yakakura-bhendi pass mafirita.

Center wavelength (CWL): Inoreva peak transmission wavelength yebhendi kana narrowband sefa, kana iyo peak inoratidzira wavelength ye bandstop sefa, iyo yepakati pakati pe 1/2 wavelength ye peak transmittance, ndiko kuti, bandwidth Iyo yepakati pe. inonzi central wavelength.

Transmittance (T): Zvinoreva kugona kupfuura kwebhendi rakanangwa, rinoratidzwa muchikamu, semuenzaniso: iyo sefa peak transmittance (Tp)> 80%, inoreva mwenje unogona kupfuura nepasefa mushure mekunyura.Kana iyo yakanyanya kukosha iri pamusoro pe80%, iyo yakakura iyo transmittance, zviri nani kugona kutapurirana kwechiedza.Yakachekwa-yekurembera: Inoshandiswa kumiririra wavelength kupindirana kweiyo simba spectral dunhu rakarasika nesefa, ndiko kuti, kureba kwewavelength kunze kwepassband.Cheka-kubvisa mwero (Block): Iyo transmittance inoenderana newavelength mune yakachekwa-renji, inozivikanwawo seIyo yakachekwa-kudzika kudzika inoshandiswa kutsanangura iyo yekucheka-kubvisa dhigirii resefa.Hazvibviri kuti chiedza chekufambisa chisvike 0. Chete kuburikidza nekuita transmittance yesefa pedyo ne zero iyo iyo isingadiwi spectrum inogona kutemwa nani.Iyo yekucheka-yero inogona kuyerwa nekutapurirana, uye zvakare inogona kuratidzwa ne optical density (OD).Hukama hweshanduko pakati payo nekutumira (T) hwakadai: OD=log10(1/T) Shanduko bhendi hupamhi: zvinoenderana nesefa Kudzika-kudzika kwakasiyana, uye hupamhi hwe spectral hunotenderwa pakati pesefa yakatemwa yakachekwa- kure nekudzika uye iyo 1/2 chinzvimbo cheiyo transmittance peak.Kukwirira kumucheto: kureva [(λT80-λT10)/λT10] *

High Reflectance (HR): Chizhinji chechiedza chinopfuura nepasefa chinoratidzwa.

High transmittance (HT): Kutapurirana kwakakwira, uye kurasikirwa kwesimba kwechiedza chinopfuura nepasefa idiki kwazvo.Angle of incidence: Kona iri pakati pechiedza chechiitiko uye yakajairwa yesefa yepasi inonzi angle yechiitiko.Kana chiedza chiri chiitiko chakatwasuka, kona yechiitiko i0 °.

Aperture inoshanda: Nzvimbo yemuviri inogona kushandiswa zvine mutsindo mumidziyo yemaziso inodaidzwa kuti aperture inoshanda, iyo inowanzofanana nehukuru hwekutaridzika kwesefa, concentric, uye idiki zvishoma muhukuru.Kutanga wavelength: Iyo yekutanga wavelength inoreva iyo wavelength inoenderana kana iyo transmittance ichikwira kusvika 1/2 yepamusoro-soro mune refu-wave pass sefa, uye dzimwe nguva inogona kutsanangurwa se5% kana 10% yepamusoro mubhendi- pass sefa Iwavelength inoenderana nekufambisa.

Kuchekwa-kure wavelength: Iyo yakachekwa-yavevelength inoreva iyo wavelength inoenderana kana iyo transmittance mupfupi-wave pass sefa yakaderedzwa kusvika 1/2 yehuwandu hwepamusoro.Mubhendi-pass sefa, dzimwe nguva inogona kutsanangurwa seyepamusoro kufambisa kwe5% kana 10%.Kureba kwewavelength kunoenderana nekupasa.
