Tlhaloso e Khutšoanyane:

Lense ea optical ea SiC e emela karolo ea optical ea boemo bo holimo e thehiloeng holim'a thepa ea silicon carbide (SiC), e nang le litekanyo le li-geometri tse ka fetoloang ka botlalo. Ho sebelisa thepa e phahameng ea optical ea SiC—ho kenyeletsoa lifensetere tse pharaletseng tsa phetiso, index e phahameng ea refractive, le li-coefficient tse matla tsa optical tse seng tsa linear—lilense tsena li fumana lits'ebetso tse pharaletseng ho photonics, litsamaiso tsa tlhahisoleseling ea quantum, le photonics e kopantsoeng.
ZMSH e fana ka lilense tsa optical tsa SiC tse sebetsang hantle (lilense tsa optical tsa silicon carbide) tse nang le litekanyo le li-geometri tse ka fetoloang ho fihlela litlhoko tse fapaneng tsa sistimi ea optical. Li entsoe ka thepa ea silicon carbide e hloekileng haholo, lilense tsena li bontša botsitso bo ikhethang ba mocheso, matla a mechini le ts'ebetso ea optical, e leng se etsang hore li be ntle bakeng sa lits'ebetso tse tsoetseng pele ho kenyeletsoa le li-laser tse matla haholo, litsamaiso tsa lifofane le li-optics tsa infrared.
Ka lebaka la ho hanyetsa mocheso o phahameng haholo, ho thatafala ha mahlaseli a kotsi, le ho tiea ha mechine ho ikhethang, lilense tsa mahlo tsa SiC li sebelisoa haholo litsamaisong tsa lifofane, mahlale a LiDAR, le litsamaisong tsa mahlo tsa ultraviolet. Motsoako oa tsona o ikhethang oa thepa ea thepa o nolofalletsa ts'ebetso e tšepahalang libakeng tse feteletseng ha ka nako e ts'oanang li boloka ts'ebetso e phahameng ea mahlo.
