A spectrometerkayan aiki ne na gani wanda ke raba hasken polychromatic zuwa bakan. Akwai nau'ikan spectrometers da yawa, baya ga na'urorin da aka yi amfani da su a cikin rukunin hasken da ake iya gani, akwai ma'aunin infrared spectrometers da ultraviolet spectrometers. Dangane da nau'ikan abubuwan rarrabawa daban-daban, ana iya raba shi zuwa spectrometer priism, spectrometer grating da tsangwama spectrometer. Dangane da hanyar ganowa, akwai spectroscopes don kallon ido kai tsaye, spectroscopes don yin rikodi tare da fina-finai masu ɗaukar hoto, da spectrophotometers don gano bakan tare da abubuwa masu ɗaukar hoto ko thermoelectric. Monochromator kayan aiki ne na bakan gizo wanda ke fitar da layin chromatographic guda ɗaya kawai ta hanyar tsaga, kuma galibi ana amfani dashi tare da sauran kayan aikin nazari.
Na'urar sifili ta yau da kullun ta ƙunshi dandamali na gani da tsarin ganowa. Ya ƙunshi manyan sassa masu zuwa:
1. Rage abin da ya faru: wurin abu na tsarin hoto na spectrometer da aka kafa a ƙarƙashin haskakawa na hasken abin da ya faru.
2. Abun haɗakarwa: hasken da ke fitar da tsaga ya zama haske iri ɗaya. Abun da ke haɗuwa yana iya zama ruwan tabarau mai zaman kansa, madubi, ko haɗa kai tsaye akan wani abu mai tarwatsewa, kamar madaidaicin grating a cikin ma'aunin ma'aunin ma'auni.
(3) Watsawa kashi: yawanci amfani da grating, don haka da cewa haske siginar a sarari bisa ga wavelength watsawa zuwa mahara bim.
4. Abun mai da hankali: Mai da hankali kan tarwatsewar katako ta yadda zai samar da jerin tsaga-tsaga hotuna a kan jirgin sama, inda kowane hoton hoton ya yi daidai da takamaiman tsayin igiyar ruwa.
5. Tsare-tsare mai ganowa: an sanya shi a kan babban jirgin sama don auna ƙarfin haske na kowane madaidaicin hoto. Tsare-tsaren ganowa na iya zama tsararrun CCD ko wasu nau'ikan tsararrun gano haske.
Mafi na kowa spectrometers a cikin manyan dakunan gwaje-gwaje su ne CT Tsarin, kuma wannan ajin na spectrometer kuma ana kiransa monochromators, wanda yawanci ya kasu kashi biyu:
1, Simmetrical off-axis scanning CT tsarin, wannan tsarin shi ne na ciki Tantancewar hanya ne gaba daya m, grating hasumiya dabaran yana da daya kawai tsakiyar axis. Saboda cikakkiyar ma'auni, za a sami rarrabuwar kawuna na biyu, wanda zai haifar da haske na musamman mai ƙarfi, kuma saboda sikanin kashe-axis ne, daidaito zai ragu.
2, asymmetric axial scanning CT tsarin, wato, na ciki Tantancewar hanya ba gaba daya m, grating hasumiya dabaran yana da biyu tsakiya gatari, don tabbatar da cewa grating juyi da aka leka a cikin axis, yadda ya kamata hana batattu haske, inganta daidaito. Zane na asymmetric in-axis scanning CT tsarin ya ta'allaka ne a kusa da mahimman abubuwa guda uku: inganta ingancin hoto, kawar da haske na biyu, da haɓaka haske mai haske.
