Izigaba zegwadle zingamathuluzi abalulekile emkhakheni wobunjiniyela bokunemba, ikakhulukazi ekuhlolweni nasekulinganisweni kwezingxenye ze-optical. Eyenziwe ngegwadle yemvelo, lezi zigaba zinikeza indawo ezinzile futhi eyisicaba, ebalulekile ukuze kuzuzwe izilinganiso ezinembile ezinhlelweni zokuhlolwa kwe-optical.
Enye yezinzuzo eziyinhloko zamapulatifomu egwadle ukucaba kwawo okuhlukile. Izingxenye ezingaphezulu zalezi zinkundla zenziwe ngomshini ngokucophelela ukuze zibe isicaba ngokwedlulele, ngokuvamile phakathi kwama-microns ambalwa. Leli zinga lokunemba libalulekile lapho kuhlolwa izingxenye ezibonakalayo ezifana namalensi nezibuko, njengoba ngisho nokuchezuka okuncane kungabangela amaphutha abalulekile ekusebenzeni. Ngokuhlinzeka ngendiza yereferensi enokwethenjelwa, amapulatifomu egwadle aqinisekisa ukuthi izingxenye ze-optical zingahlelwa ngokunembile futhi zikalwe.
I-Granite nayo yaziwa ngokuqina kwayo nokumelana nokugqoka. Ngokungafani nezinye izinto ezingase ziwohloke noma ziguge ngokuhamba kwesikhathi, i-granite igcina ubuqotho bayo, iqinisekisa ukuthi indawo yokuhlola ihlala ingaguquki phakathi nesikhathi eside. Lokhu kuzinza kubaluleke kakhulu ekuhlolweni kwe-optical, lapho ukulinganisa okuphindaphindiwe kufanele kuveze imiphumela ethembekile. Izakhiwo ze-Granite zemvelo ziyenza futhi ingathinteki ekunwebeni okushisayo, okungathinta ukunemba kokulinganisa. Lesi sici sibalulekile ezindaweni lapho ukuguquka kwezinga lokushisa kuvame khona.
Ukwengeza, amapulatifomu e-granite avame ukusetshenziswa nemishini yokuhlola ehlukahlukene, njengama-interferometer nama-autocollimators. Lawa madivayisi adinga inkundla ezinzile ukuze asebenze ngempumelelo, futhi amapulatifomu egwadle ahlinzeka ngosekelo oludingekayo. Inhlanganisela yendawo eyisicaba ye-granite kanye nokuqina ivumela ukuqondanisa okunembayo kanye nokuma kwezingxenye ze-optical, okusiza ukuhlola nokuhlola okunembile.
Sengiphetha, amapulatifomu e-granite adlala indima ebalulekile ekuhlolweni kwengxenye ye-optical. Ukucaba kwazo okungenakuqhathaniswa, ukuqina, kanye nokuzinza kuzenza zibe izinto ezibalulekile ekuqinisekiseni ukunemba nokuthembeka kwezilinganiso ze-optical, ekugcineni kube negalelo ekuthuthukisweni kobuchwepheshe be-optical.
