Phetiso e Phahameng ea Bohloeki bo Phahameng ba Sapphire Optical ≥90%

Setšoantšo se Hlahisitsoeng sa Sapphire Optical Windows se Ikhethileng ≥90%

Tlhaloso e Khutšoanyane:

Lifensetere tsa optical tsa sapphire ke likarolo tse ikhethileng tsa optical tse entsoeng ka aluminium oxide e le 'ngoe ea kristale (Al₂O₃), e tsebahalang ka ts'ebetso ea eona e ikhethang ea optical, matla a mechini, le botsitso ba lik'hemik'hale. Jwalo ka kristale e thata ka ho fetisisa ea oxide (boima ba Mohs 9), lifensetere tsa sapphire li bontša phetisetso e ntle haholo (~83-85% e sa koaheloang) ho pholletsa le ultraviolet (200nm) ho ea ho mid-infrared (5.5μm) spectra, e leng se etsang hore li be ntle bakeng sa lits'ebetso tse hlokang ponaletso e phahameng le ho tšoarella.

Tlhahiso e kenyelletsa lits'ebetso tsa bohlokoa ho kenyeletsoa kholo ea tataiso ea kristale, ho arola ka nepo, ho bentša ka nanoscale, le ho penta ka mokhoa o ikhethileng. Mekhoa e tsoetseng pele ea kholo (mohlala, mekhoa ea HEM kapa KY) e hlahisa li-boule tsa boleng bo holimo tse nang le sekoli se tlase (<10⁴/cm²). Sebopeho se ikhethang sa kristale sa hexagonal se nolofalletsa thepa ea anisotropic, ka tataiso e ntlafalitsoeng (li-C-axis, A-axis, kapa R-plane cuts) e etsang hore ts'ebetso ea optical e lumellane le lits'ebetso tse itseng.

Litšobotsi tsa Bohlokoa

1. Ho Ikamahanya le Tikoloho ka ho Feteletseng
Lifensetere tsa optical tsa safire li bonts'a ts'ebetso e ikhethang ka ntlha ea ho qhibiliha ea 2053°C, li boloka botsitso ba sebopeho maemong a ts'ebetso a 1000°C a tsoelang pele. Ho tsitsa hona ha mocheso ho nolofalitsoe ke coefficient e tlase haholo ea katoloso ea mocheso (CTE) ea 5.3×10⁻⁶/K ho potoloha C-axis, e phahametseng haholo likhalase tsa optical tse tloaelehileng. Ka lik'hemik'hale, lifensetere tsa optical tsa safire li bontša ho se sebetse hantle ho makatsang, li hanela li-acid tsohle tse matla (ntle le HF) le alkalis, e leng se etsang hore li be ntle bakeng sa lisebelisoa tsa ts'ebetso ea lik'hemik'hale le lits'ebetso tsa metsing. Ka mechini, lifensetere tsena li na le matla a ho thiba a fetang 1000MPa (makhetlo a 5-8 a matla ho feta khalase e tloaelehileng ea optical) ka khanyetso e ikhethang ea tšusumetso.

2. Melemo ea Tshebetso ea Optical
Lifensetere tsa optical tsa safire li fana ka phetiso ea >80% ho pholletsa le sebaka se seholo sa spectral (200-5500nm ka botenya ba 2mm). Ka ho shebana le kristale e ntlafalitsoeng (mohlala, C-axis e otlolohileng ho ea tseleng ea leseli), litlamorao tsa birefringence lia fokotsoa ka katleho. Boleng ba bokaholimo bo fihlela litlhoko tse thata tsa optical ka ho batalatsa ha λ/10 ho 633nm le ho ba thata ha bokaholimo <0.5nm RMS.

3. Bokgoni ba ho Etsa Dihlahiswa bo tswetseng pele
