Spektrometa yehardware yekuona zviratidzo zveOptical

Kuonekwa kwechiratidzo chemazisospectromita yehardware
A spectromitachishandiso che optical chinoparadzanisa chiedza che polychromatic kuita spectrum. Kune mhando dzakawanda dze spectrometers, kuwedzera kune spectrometers dzinoshandiswa mu visible light band, kune infrared spectrometers uye ultraviolet spectrometers. Zvichienderana ne dispersion elements dzakasiyana, inogona kukamurwa kuita prism spectrometer, grating spectrometer uye interference spectrometer. Zvichienderana ne detection method, kune spectroscopes ye direct eye observation, spectroscopes yekurekodha nema photosensitive films, uye spectrophotometers yekuona spectra ine photoelectric kana thermoelectric elements. Monochromator chishandiso che spectral chinoburitsa chromatographic line imwe chete kuburikidza ne slit, uye chinowanzo shandiswa pamwe chete nezvimwe zvishandiso zve analytical.
Spektrometer yakajairika ine chikuva chekuona uye sisitimu yekuona. Inosanganisira zvikamu zvikuru zvinotevera:
1. Kutsemuka kwechiitiko: nzvimbo yechinhu chiri muchimiro chemifananidzo yespectrometer inoumbwa pasi pekuvhenekerwa nechiedza chechiitiko.
2. Chinhu cheCollimation: chiedza chinoburitswa nepaburi chinova chiedza chakafanana. Chinhu cheCollimating chinogona kunge chiri lenzi yakazvimiririra, girazi, kana kuti chakabatanidzwa zvakananga pane chinhu chinopararira, senge concave grating mu concave grating spectrometer.
(3) Chinhu chekupararira: chinowanzo shandiswa grating, kuitira kuti chiratidzo chechiedza muchadenga zvichienderana nekupararira kwewavelength mumatanda akawanda.
4. Chinhu chinotarisisa: Tarisa danda rinopararira kuitira kuti rigadzire mifananidzo yakatevedzana yezviitiko zvakatsemuka panzvimbo yakatarisana, uko poindi yega yega yemufananidzo inoenderana nehurefu hwewavelength hwakatarwa.
5. Detector array: yakaiswa panzvimbo yakatarisana yekuyera kusimba kwechiedza chemufananidzo wega wega we wavelength. Detector array inogona kuva CCD array kana mamwe marudzi e light detector array.
Maspectrometer anonyanya kuzivikanwa mumarabhoritari makuru ma CT structures, uye boka iri remaspectrometer rinonziwo monochromators, ayo akakamurwa zvikuru muzvikamu zviviri:
1, chimiro cheCT chekuenzanisa symmetrical off-axis scanning, chimiro ichi chiri mukati me optical path chakasiyana zvachose, vhiri re grating tower rine central axis imwe chete. Nekuda kwekuenzana kwakazara, pachava nekupararira kwechipiri, zvichikonzera chiedza chakasimba, uye nekuti chiri off-axis scan, kururama kuchaderedzwa.
2, chimiro cheCT cheaxial scanning chisina kuenzana, kureva kuti, nzira yemukati ye optical haina kuenzana zvakakwana, vhiri re grating tower rine ma axes maviri epakati, kuitira kuti kutenderera kwe grating kuskenwe mu axis, zvinobudirira kudzivirira chiedza chisina kujeka, uye kunatsiridza kururama. Dhizaini yechimiro cheCT che asymmetric in-axis scanning inotenderera pazvinhu zvitatu zvakakosha: kugadzirisa kunaka kwemufananidzo, kubvisa chiedza chechipiri chakapararira, uye kuwedzera kuyerera kwechiedza.

Spectroscope (Spectroscope) chishandiso chesainzi chinoparadzanisa chiedza chakaoma kuita mitsetse yespectral, ine maprism kana diffraction gratings, nezvimwewo, ichishandisa spectrometer kuyera chiedza chinoonekwa kubva pamusoro pechinhu. Chiedza chine mavara manomwe muzuva chikamu cheziso chisina kusimba chinogona kukamurwa (chiedza chinooneka), asi kana spectrometer ikaora zuva, zvichienderana nekurongeka kwewavelength, chiedza chinooneka chinongotarisa diki diki yespectrum, zvimwe zvese ziso risina kusimba harigone kusiyanisa spectrum, senge infrared, microwave, ultraviolet, X-ray nezvimwewo. Kuburikidza nekutora ruzivo rwechiedza nespectrometer, kugadzirwa kwemaplate emifananidzo, kana kuratidzwa otomatiki kwezvishandiso zvenhamba nekombiyuta, kuitira kuti zvionekwe kuti ndezvipi zvinhu zviri muchinyorwa. Iyi tekinoroji inoshandiswa zvakanyanya mukuona kusvibiswa kwemhepo, kusvibiswa kwemvura, hutsanana hwechikafu, indasitiri yesimbi nezvimwewo.
