Iinkcazo zokusebenza kwesihluzi ziinkcazo eziyimfuneko zentsebenzo yokucoca ngolwimi olunokuqondwa lula ngabaqulunqi benkqubo, abasebenzisi, abavelisi bokucoca, njl.njl Ngamanye amaxesha zibhalwa ngumenzi wecebo lokucoca ngokusekelwe ekusebenzeni okufezekisiweyo kwesihluzi, mhlawumbi kumsebenzisi, okanye ikhathalogu yemveliso eqhelekileyo engasetyenziswanga ngokucacileyo, eyokugqibela esingayi kuxoxa ngayo apha. Kwiimeko ezininzi, iinkcukacha zokusebenza zihlala zibhalwa ngumyili wenkqubo.
Ukuze ufumane umsebenzi ofunekayo kwinkqubo, umyili uchaza umsebenzi ofunekayo wesihluzi kwi-metric. Ekubhaleni imetriki enjalo, umbuzo wokuqala ekufuneka uphendulwe ngulo: Sisetyenziselwa ntoni isihluzo? Injongo yesihluzi kufuneka icaciswe gca nakakade, kwaye oku kuya kuba sisiseko sokubhala. Ngokwenene akukho ndlela icwangcisiweyo yokuchaza iinkcukacha zokusebenza. Ngamanye amaxesha ukusebenza kwenkqubo apho isihluzi sifakwe khona kufuneka sibe kwinqanaba elithile, ngaphandle koko akuyi kugxilwa kwinkcazo engaphezulu. Iimfuno zokusebenza zesihluzi kufuneka zimiselwe ngokulula, kodwa oku akusoloko kungumsebenzi olula. Akukho zimfuneko zipheleleyo zokusebenza; ukusebenza kufuneka kube phezulu njengoko ubunzima okanye ixabiso elinokwenzeka livumela. Kule meko, inkqubo isebenzisa izihlungi zentsebenzo eyahlukeneyo, kwaye ukusebenza kufuneka kulinganiswe neendleko zayo, ubunzima, kunye nokukwazi ukwenza izigwebo malunga nengqiqo. I-metric yokugqibela iya kuba kukuhambelana phakathi kwezinto ezifunekayo kunye noko kufezekiswayo. Oku kudla ngokufuna igalelo loyilo olukhulu kunye nolwazi lokwenziwa, kunye nonxibelelwano olusondeleyo phakathi komsebenzisi kunye nomenzi. Kubalulekile ukukhumbula ukuba iinkcukacha ezingayonelisiyo izicelo ezenziwayo zezomdla nje kwizifundo. Njengomzekelo, makhe siqwalasele ngokufutshane ingxaki: indlela yokufumana umgca we-spectral kwi-spectrum eqhubekayo. Ngokucacileyo, isihluzo esincinci siyafuneka, kodwa yeyiphi i-bandwidth kunye noluphi uhlobo lokucoca olufunekayo? Amandla omgca we-spectral ohanjiswa sisihluzo uya kuxhomekeka ngokukodwa kwincopho yokuhanjiswa kwayo (ucinga ukuba indawo encopho yesihluzi inokuhlala ihlengahlengiswa kumgca we-spectral kwingxaki), ngelixa amandla e-spectrum eqhubekayo aya kuxhomekeka kwindawo epheleleyo engaphantsi kwe-curve ye-transmittance, kubandakanywa nommandla we-wavelength cutoff kude nencopho. I-passband emxinwa, iphezulu umehluko phakathi kwe-harmonic continuum kunye ne-spectrum eqhubekayo, ngakumbi njengoko i-passband iba yincinci, eyenza ngokubanzi i-cutoff. Nangona kunjalo, i-passband encinci, iya kuba yindleko ngakumbi ukuvelisa, ekubeni ukucutha kwe-passband kwandisa ubunzima bokuvelisa; kwaye iya kwenza umlinganiselo ovumelekileyo wojoliso ube mkhulu, kuba inyusa ngakumbi ubuntununtunu kwi-optical noncollimation. Inqaku lokugqibela apha lithetha ukuba kwintsimi efanayo yokujonga, i-bandwidth encinci ye-filter kufuneka yenziwe ibe nkulu, ukwenzela ukuba i-focal ratio enkulu isetyenziswe, kodwa oku kuya kwandisa ubunzima bokwenza kunye nobunzima benkqubo yonke. Enye indlela yokuphucula ukusebenza kwesihluzi kukwandisa umda we-passband kodwa ulondoloze i-bandwidth efanayo. Imilo yebhendi yoxande inomahluko ophezulu kunesihluzo esilula seFabry-Perot esinobubanzi obusisiqingatha esifanayo, kwaye i-passband inenzuzo eyongeziweyo yokuba i-cutoff kude nencopho yokucoca nayo iba nkulu. Ukuchaza lo mda wokunyuka nge-1/10 bandwidth okanye i-1/100 bandwidth inokumiselwa. Kwakhona, okukhona ubukhali, kokukhona kuba nzima kwaye kubiza kakhulu ukuvelisa.
