Kuonekwa kwechiratidzo cheOpticalhardware spectrometer
A spectrometerchiridzwa chemaziso chinoparadzanisa chiedza chepolychromatic kuita spectrum. Kune mhando dzakawanda dzema spectrometers, kuwedzera kune ma spectrometers anoshandiswa mubhendi rechiedza rinooneka, kune infrared spectrometers uye ultraviolet spectrometers. Zvinoenderana neakasiyana ekuparadzira zvinhu, inogona kukamurwa kuita prism spectrometer, grating spectrometer uye interference spectrometer. Zvinoenderana nemaitiro ekuona, kune ma spectroscopes ekutarisa kwakananga ziso, ma spectroscopes ekurekodha ane photosensitive mafirimu, uye spectrophotometers ekuona spectra ine photoelectric kana thermoelectric zvinhu. A monochromator chiridzwa chinotaridzika chinoburitsa chete mutsara mumwechete wekromatographic kuburikidza nekutsemuka, uye chinowanzoshandiswa pamwe chete nezvimwe zviridzwa zvekuongorora.
Yakajairika spectrometer ine optical platform uye yekuona system. Inosanganisira zvikamu zvikuru zvinotevera:
1. Incident slit: chinhu chinongedzo cheiyo imaging system ye spectrometer yakaumbwa pasi pekuvhenekerwa kwechiedza chechiitiko.
2. Collimation element: mwenje unoburitswa ne slit unova parallel light. Iyo collimating element inogona kunge yakazvimiririra lenzi, girazi, kana yakanyatsobatanidzwa pane inoparadzira chinhu, senge concave grating mune concave grating spectrometer.
(3) Dispersion element: kazhinji kushandisa grating, kuitira kuti chiratidzo chechiedza munzvimbo maererano newavelength dispersion mumatanda akawanda.
4. Focusing element: Nangidzira danda rinoparadzira kuitira kuti riite nhevedzano yezviitiko zvakatsemuka mifananidzo pane yakatarisa ndege, apo poindi yemufananidzo wega wega inoenderana nehurefu hwakati.
5. Detector array: yakaiswa pafocal plane yekuyera kupenya kwechiedza chega chega chewavelength image point. Iyo detector array inogona kuve yeCCD array kana mamwe marudzi emwenje detector array.
Iwo anonyanya kuzivikanwa ma spectrometers mumarabhoritari makuru ndeye CT zvimiro, uye iyi kirasi yema spectrometers inonziwo monochromators, iyo inonyanya kukamurwa kuita mapoka maviri:
1, symmetrical off-axis scanning CT chimiro, chimiro ichi inzira yemukati yekuona yakanyatsoenderana, vhiri reshongwe yegumbo rine imwe chete yepakati axis. Nekuda kwekuenzanisa kwakazara, pachave nechipiri diffraction, zvichikonzera kunyanya kusimba kwechiedza, uye nekuti iri off-axis scan, huchokwadi huchadzikiswa.
2, asymmetric axial scanning CT chimiro, ndiko kuti, nzira yemukati yekuona haina kuenzana zvachose, vhiri regiya regiya rine matemo maviri epakati, kuve nechokwadi chekuti kutenderera kwegiredhi kunoongororwa muaxis, kuvharisa chiedza chakarasika, kuvandudza kurongeka. Dhizaini yeasymmetric in-axis scanning CT chimiro inotenderedza mapoinzi matatu akakosha: kukwenenzvera mhando yemufananidzo, kubvisa chechipiri chakaparadzaniswa chiedza, uye kuwedzera kupenya kupenya.

Spectroscope (Spectroscope) chiridzwa chesainzi chinotyora mwenje wakaoma kuita mitsara inotaridzika, inoumbwa nemaprism kana diffraction gratings, zvichingodaro, vachishandisa spectrometer kuyera chiedza chinoratidzwa kubva pamusoro pechinhu. Chiedza chine mavara manomwe muzuva chikamu cheziso rakashama chinogona kukamurwa (chiedza chinooneka), asi kana iyo spectrometer ichizoora zuva, zvinoenderana newavelength kurongeka, chiedza chinooneka chinongoverengera diki diki re spectrum, zvimwe ziso rakashama harigoni kusiyanisa spectrum, zvakadai se infrared, microwave, ultraviolet, X-ray uye zvichingodaro. Kuburikidza nekutorwa kweruzivo rwechiedza ne spectrometer, kugadzirwa kwemahwendefa emifananidzo, kana kuratidzwa kwekombuta otomatiki yezviridzwa zvenhamba kuratidza uye kuongorora, kuitira kuti uone kuti ndezvipi zvinhu zviri muchinyorwa. Iyi tekinoroji inoshandiswa zvakanyanya mukuona kusvibiswa kwemhepo, kusvibiswa kwemvura, hutsanana hwekudya, indasitiri yesimbi nezvimwe.
