Umhlinzeki Welensi Eqondile Yefekthri
Ngenxa yokuthi ingilazi yesafire inekhono eliphelele lokudlulisa i-spectrum kusuka ku-ultraviolet kuya ku-infrared, imikhiqizo ye-lens eyenziwe ngesafire ayikwazi nje ukuba nempilo ende yesevisi, kodwa futhi ivumelane ne-spectra ehlukahlukene, ukuze kuncishiswe ukusetshenziswa kwengilazi ye-optical nokunciphisa ivolumu ithuluzi.

Izinto ezibonakalayo
I-Sapphire iyi-crystal aluminium oxide eyodwa (Al2O3). Ingenye yezinto eziqinile kakhulu. I-Sapphire inezici ezinhle zokudlulisela ngaphezulu kokubonakalayo, futhi eduze ne-IR spectrum. Ibonisa amandla aphezulu emishini, ukumelana namakhemikhali, ukuqhutshwa kwe-thermal kanye nokuzinza kokushisa. Ivamise ukusetshenziswa njengezinto zefasitela emkhakheni othize njengobuchwepheshe besikhala lapho kudingeka khona ukuklwebheka noma ukumelana nezinga lokushisa eliphezulu.
