Indima yeGranite ekukhiqizweni kwamaLensi Asezingeni Eliphezulu.

 

I-Granite, idwala lemvelo eliyi-igneous elakhiwe ngokuyinhloko yi-quartz, i-feldspar kanye ne-mica, idlala indima ebalulekile kodwa evame ukunganakwa ekukhiqizweni kwamalensi anembe kakhulu. Izakhiwo ezihlukile ze-Granite zenza kube yinto efanelekile yezinhlelo zokusebenza ezahlukahlukene embonini yokukhanya, ikakhulukazi ekukhiqizweni kwamalensi asezingeni eliphezulu amakhamera, ama-microscope kanye nama-telescope.

Enye yezinzuzo eziyinhloko ze-granite ukuzinza kwayo okumangalisayo. Lapho wenza amalensi anembe kakhulu, ukugcina indawo ehlala njalo nezinzile kubalulekile ukuqinisekisa ukucaca nokunemba kokukhanya. I-coefficient ephansi yokwanda kokushisa kwe-granite isho ukuthi ngeke igobe noma iguquguquke ngokushintshashintsha kwezinga lokushisa, okwenza kube yinto eyisisekelo efanelekile yokugaya nokupholisha amalensi. Lokhu kuzinza kuvumela abakhiqizi ukuthi bafinyelele ukubekezelelana okunembile okudingekayo kwezingxenye ze-optical ezisebenza kahle kakhulu.

Ubulukhuni be-granite buyenza ibaluleke kakhulu ekukhiqizweni kwelensi. Le nto ingamelana nezinqubo ezinzima zokugaya nokupholisha ezidingekayo ukuze kudalwe izindawo ezibushelelezi nezingenaphutha ezidingekayo kumalensi anokunemba okuphezulu. Ngokungafani nezinto ezithambile, i-granite ayigugi kalula, okuqinisekisa ukuthi amathuluzi asetshenziswa ekukhiqizweni kwelensi azogcina ukusebenza kwawo ngokuhamba kwesikhathi. Lokhu kuqina konga imali kubakhiqizi ngoba bangathembela emishinini ye-granite isikhathi eside ngaphandle kokuyishintsha njalo.

Ngaphezu kwalokho, ubuhle bemvelo be-granite kanye nemibala eyahlukahlukene kungathuthukisa ukukhanga kobuhle bamadivayisi okukhanya. Nakuba ukusebenza kubalulekile, umthelela obonakalayo wamalensi anembe kakhulu kanye nezindawo zawo zokubeka kungathinta nokukhetha kwabathengi. Ukusebenzisa i-granite kulezi zinhlelo zokusebenza akugcini nje ngokunikeza isisekelo esiqinile nesithembekile, kodwa futhi kunezela nesici sobuhle.

Ngamafuphi, izakhiwo ezihlukile ze-granite (ukuzinza, ubulukhuni, kanye nobuhle) zenza ibe yinto ebalulekile ekukhiqizeni amalensi anembe kakhulu. Njengoba isidingo sobuchwepheshe obuthuthukisiwe be-optical siqhubeka sikhula, indima ye-granite embonini cishe izoba yinto ebaluleke kakhulu, okuqinisekisa ukuthi abakhiqizi bangahlangabezana nezindinganiso eziqinile ezidingekayo ekusebenzeni kwe-optical kwekhwalithi ephezulu.
