Igranite, iliwa lendalo elivutha umlilo elenziwe ikakhulu iquartz, i-feldspar kunye ne-mica, idlala indima ebalulekileyo kodwa ihlala ingahoywa ekuvelisweni kweelensi ezichanekileyo. Iimpawu ezikhethekileyo zeGranite zenza ukuba ibe yinto efanelekileyo kwizicelo ezahlukeneyo kwishishini le-optical, ngakumbi ukuveliswa kweelensi ezikumgangatho ophezulu kwiikhamera, ii-microscopes kunye ne-telescopes.
Enye yeenzuzo eziphambili zegranite kukuzinza kwayo okungaqhelekanga. Xa usenza iilensi ezichanekileyo, ukugcina indawo ehambelanayo kunye nokuzinza kubalulekile ukuqinisekisa ukucaca kunye nokuchaneka kwe-optical. I-coefficient ephantsi ye-Granite yokwandiswa kwe-thermal ithetha ukuba ayizugoba okanye igxumeke ngokuguquguquka kweqondo lobushushu, iyenze ibe sisixhobo esisisiseko esifanelekileyo sokusila iilensi kunye nezixhobo zokupolisha. Oku kuzinza kuvumela abavelisi ukuba bafezekise ukunyamezela okuchanekileyo okufunekayo kumacandelo aphezulu okusebenza.
Ukuqina kwe-Granite kwenza ukuba ibaluleke kwimveliso yelensi. Izinto eziphathekayo zinokumelana neenkqubo ezingqongqo zokusila kunye nokupholisha okufunekayo ukudala iindawo ezigudileyo, ezingenasiphako ezifunekayo kwiilensi ezichanekileyo. Ngokungafaniyo nezinto ezithambileyo, i-granite ayinxibi lula, iqinisekisa ukuba izixhobo ezisetyenziswa kwimveliso yelensi ziya kugcina ukusebenza kwazo ngokuhamba kwexesha. Oku kuhlala konga imali yabavelisi kuba banokuthembela kwisixhobo segranite ixesha elide ngaphandle kokusitshintsha rhoqo.
Ukongeza, ubuhle bendalo be-granite kunye nemibala eyahlukeneyo inokunyusa umtsalane wobuhle bezixhobo zokukhanya. Ngelixa ukusebenza kubalulekile, impembelelo yembonakalo yeelensi ezichanekileyo kunye nezindlu zazo zinokuchaphazela ukhetho lwabathengi. Ukusebenzisa i-granite kwezi zicelo akunikezeli nje isiseko esomeleleyo nesithembekileyo, kodwa songeza into yobuhle.
Isishwankathelo, iipropathi ezikhethekileyo zegranite (ukuzinza, ukuqina, kunye nobuhle) zenza ukuba kube yinto ebalulekileyo yokuvelisa iilensi ezichanekileyo. Njengoko imfuno yetekhnoloji ye-optical ephucukileyo iqhubeka nokukhula, indima yegranite kushishino kusenokwenzeka ukuba ibaluleke ngakumbi, iqinisekisa ukuba abavelisi banokuhlangabezana nemigangatho engqongqo efunekayo ekusebenzeni komgangatho ophezulu wokukhanya.
