Zvinodiwa pakushanda kwefirita itsananguro dzinodiwa pakushanda kwefirita mumutauro unogona kunzwisiswa zviri nyore nevagadziri vemasisitimu, vashandisi, vagadziri vefirita, nezvimwewo. Dzimwe nguva mugadziri wefirita anonyora zvinodikanwa zvichibva pakushanda kwefirita. Dzimwe nguva zvinonyorwa nemugadziri wefirita zvichibva pakushanda kwefirita, kungave kumushandisi, kana kune katalogi yezvigadzirwa yakajairwa isingashandiswe zvakajeka, yekupedzisira yatisingazokurukure pano. Kazhinji, zvinodikanwa pakushanda zvinowanzonyorwa nemugadziri wesisitimu.
Kuti awane mashandiro anodiwa kubva kuhurongwa, mugadziri anotsanangura mashandiro anodiwa ehupfu hwesefa nenzira yekuenzanisa. Pakunyora chiyero chakadaro, mubvunzo wekutanga unofanirwa kupindurwa ndewekuti: Hupfu hwesefa hunoshandiswa chii? Chinangwa chehupfu hwesefa chinofanira kutsanangurwa zvakajeka uye nemazvo, uye ichi ndicho chichava hwaro hwekunyora. Hapana nzira yakarongeka yekutsanangura ruzivo rwekushanda. Dzimwe nguva mashandiro ehurongwa hwesefa hunofanirwa kunge huri padanho rakati, zvikasadaro hapazovi nekutarisisa mune imwe tsananguro. Zvinodiwa zvekushanda kwehupfu hwesefa zvinofanirwa kutsanangurwa zviri nyore, asi izvi hazviwanzo kuve nyore. Hapana zvinodiwa zvakakwana zvekushanda; mashandiro anofanira kunge akakwira sezvinobvumidzwa nekuomarara kana mutengo unogoneka. Muchiitiko ichi, hurongwa hunoshandisa mafirita ekushanda kwakasiyana, uye mashandiro anofanira kuenzaniswa nemutengo wayo, kuomarara, uye kugona kuita sarudzo pamusoro pezvinonzwisisika. Chiyero chekupedzisira chichava kubvumirana pakati pezvinodiwa nezvinogona kuitwa. Izvi zvinowanzoda ruzivo rwakawanda rwekugadzira nekugadzira, uye kutaurirana kwepedyo pakati pemushandisi nemugadziri. Zvakakosha kuyeuka kuti zvirevo zvisingagutse mashandisirwo anoshanda zvinongori zvedzidzo chete. Semuenzaniso, ngatifungei muchidimbu nezvedambudziko iri: nzira yekuwana mutsetse wespectral mu continuous spectrum. Zviri pachena kuti, firita re narrowband rinodiwa, asi bandwidth ipi uye rudzii rwefirita runodiwa? Simba remutsetse wespectral unotumirwa nefirita rinonyanya kutsamira pakutumira kwaro kwepamusoro (tichifunga kuti nzvimbo yepamusoro yefirita inogona kugadziriswa nguva dzose kune mutsetse wespectral mudambudziko), nepo simba re continuum spectrum richitsamira panzvimbo yese iri pasi pe transmittance curve, kusanganisira nzvimbo ye wavelength cutoff kure ne peak. Kana passband yakamanikana, musiyano uripo pakati pe harmonic continuum ne continuous spectrum wakakwira, kunyanya sezvo passband ichiva yakamanikana, izvo zvinowanzowedzera cutoff. Zvisinei, kana passband yakamanikana, ichave inodhura zvikuru kugadzira, sezvo kupfupika kwepassband kunowedzera kuoma kwekugadzira; uye zvichaitawo kuti allowable focal ratio ikure, sezvo inowedzerawo kunzwa kune optical noncollimation. Pfungwa yekupedzisira pano inoreva kuti pakuona kumwe chete, bandwidth yakamanikana yefirita inofanira kuitwa yakakura, kuitira kuti ratio yakakura yefocal ishandiswe, asi izvi zvichawedzera kuoma kwekugadzira uye kuoma kwesystem yese. Imwe nzira yekuvandudza mashandiro efirita ndeyekuwedzera kukwira kwemucheto kwebhandi asi uchiramba uine bandwidth imwechete. Chimiro chebhandi re rectangular chine musiyano wakakwira kupfuura firita iri nyore yeFabry-Perot ine hafu yehupamhi, uye bhandi re passband rine mukana wekuwedzera wekuti cutoff kubva pa filter peak inovawo yakakura. Kutsanangura kukwira kwemucheto uku ne 1/10 bandwidth kana 1/100 bandwidth kunogona kutsanangurwa. Zvakare, kana mucheto wakadzika, zvinova zvakaoma uye zvinodhura kugadzira.
