Izigaba ze-granite ziyithuluzi elibalulekile emkhakheni wobunjiniyela bokunemba, ikakhulukazi ekuhlolweni nasekulinganisweni kwezingxenye ze-optical. Zenziwe nge-granite yemvelo, lezi zigaba zinikeza indawo ezinzile neyisicaba, ebalulekile ekufezeni izilinganiso ezinembile ekusetshenzisweni kokuhlolwa kwe-optical.
Enye yezinzuzo eziyinhloko zamapulatifomu e-granite ukuthi ayisicaba ngendlela emangalisayo. Ubuso balezi zinkundla buhlelwe ngomshini ngokucophelela ukuze bube yisicaba kakhulu, ngokuvamile ngaphakathi kwama-micron ambalwa. Leli zinga lokunemba libalulekile lapho kuhlolwa izingxenye ezibonakalayo ezifana namalensi nezibuko, njengoba ngisho nokuphambuka okuncane kakhulu kungabangela amaphutha amakhulu ekusebenzeni. Ngokunikeza indiza yokubhekisela ethembekile, amapulatifomu e-granite aqinisekisa ukuthi izingxenye ezibonakalayo zingalinganiswa ngokunembile futhi zilinganiswe.
I-Granite yaziwa nangokuhlala kwayo isikhathi eside kanye nokumelana nokuguguleka. Ngokungafani nezinye izinto ezingase ziguge noma ziguge ngokuhamba kwesikhathi, i-granite igcina ubuqotho bayo, iqinisekisa ukuthi indawo yokuhlola ihlala ifana isikhathi eside. Lokhu kuzinza kubaluleke kakhulu ekuhlolweni kokukhanya, lapho ukulinganisa okuphindaphindiwe kufanele kuveze imiphumela ethembekile. Izakhiwo ze-Granite ezingokwemvelo nazo ziyenza ingathinteki kakhulu ekukhuleni kokushisa, okungathinta ukunemba kokulinganisa. Lesi sici sibalulekile ezindaweni lapho ukuguquguquka kwezinga lokushisa kuvame khona.
Ngaphezu kwalokho, amapulatifomu e-granite avame ukusetshenziswa nemishini eyahlukahlukene yokuhlola i-optical, njenge-interferometers kanye nama-autocollimator. Lawa madivayisi adinga ipulatifomu ezinzile ukuze asebenze kahle, futhi amapulatifomu e-granite ahlinzeka ngokusekelwa okudingekayo. Ukuhlanganiswa kobuso obuyisicaba be-granite kanye nokuqina kuvumela ukuhambisana okunembile kanye nokubekwa kwezingxenye ze-optical, okwenza kube lula ukuhlola nokuhlola okunembile.
Ekuphetheni, amapulatifomu e-granite adlala indima ebalulekile ekuhlolweni kwezingxenye ze-optical. Ukuthamba kwawo okungenakuqhathaniswa, ukuqina, kanye nokuqina kuwenza abe yinto ebalulekile yokuqinisekisa ukunemba nokuthembeka kwezilinganiso ze-optical, ekugcineni okunegalelo ekuthuthukisweni kobuchwepheshe be-optical.
