Silicon Carbide Prism / Seipone Bakeng sa Infrared Optics Aerospace-Grade

Tlhaloso e Khutšoanyane:

Seipone se bataletseng sa silicon carbide (SiC) ke karolo ea boleng bo holimo ea optical e entsoeng ka ceramic e tsoetseng pele ea SiC. E na le karolelano e ikhethang ea ho tiea-ho-boima, ts'ebetso e phahameng ea infrared, le botsitso bo ikhethang ba tikoloho, ke khetho e ntle bakeng sa litsamaiso tsa optical tse hlokang boiteko. Ha li bapisoa le thepa ea setso e kang fused silica, germanium, le zinc selenide, liipone tsa SiC ha li ipabole feela ho spectrum ea infrared e bohareng ho isa ho e hole empa hape li fana ka bobebe, matla a phahameng a mechini, le botsitso ba nako e telele tlas'a maemo a thata a ts'ebetso.

Kakaretso

Seipone sena se sebelisoa haholo ho lisebelisoa tsa ho lekanya matla a sefofane, litsamaisong tsa laser, litšoantšong tsa infrared, le metrology e nepahetseng haholo.

Likarolo tsa Bohlokoa

Ntlafatso e bobebe ea sebopeho: Moralo o tsoetseng pele o nang le dibopeho tsa mahe a dinotshi le tsa topology o fokotsa boima ntle le ho tela matla.
E bobebe haholo: E bobebe haholo ho feta di-substrate tsa seipone tse tlwaelehileng, tse bohlokwa bakeng sa di-platform tsa sefofane le tsa mehala.
Ho satalla ho hoholo: E boloka ho nepahala ha sebopeho sa bokaholimo esita le ka sebopeho se seholo sa lesoba le seipone se sesesaane.
Katoloso e tlase ea mocheso: E netefatsa ts'ebetso ea optical ho pholletsa le liphetoho tse potlakileng kapa tse feteletseng tsa mocheso.
Ho hanyetsa ho ngoapa le ho robeha: Ho thatafala ho lekana le taemane, ho hanela ho kgohlana ha tikoloho.
Qetello e phahameng ea bokaholimo: Bophara ≤ 1 μm, boleng ba bokaholimo bo loketse bakeng sa ho nka litšoantšo tse boima le lits'ebetso tsa laser.

Melemo ea Tshebetso

Botsitso bo phahameng ba modulus le tekanyo: Modulus e tenyetsehang ho fihlela ho 420–450 GPa, e netefatsang ts'ebetso e tsitsitseng tlasa meroalo e boima le ho thothomela.
Ho sotha mocheso ho fokolang: Koefficient e tlase haholo ea katoloso ea mocheso (CTE), e netefatsang botsitso ba optical libakeng tse feto-fetohang tsa mocheso.
Ho hanyetsa ho ts'oaroa ke mocheso le ho bola: E tsitsitse khahlanong le tikoloho ea asiti/alkali 'me e hanela ho feto-fetoha ha mocheso ka potlako.
Sebopeho se senyenyane se teteaneng, se se nang masoba: Bongata ba bongata ho fihlela ho 3.14 g/cm³ ntle le masoba a setseng ka mora ho sebetsa, e leng se fanang ka ho bonahatsa hantle le botsitso ba sebopeho.

Likopo

Mabone a infrared: Litsamaiso tsa ho nka litšoantšo tsa infrared e mahareng le e hole, lik'hamera tsa mocheso, le optics ea ho shebella.
Lisebelisoa tsa laser le tsa optoelectronics: Liipone tsa laser tse matla haholo, setering sa mahlasedi, le dikopano tsa optical tse bontshang lesedi.
Lifofane le bolepi ba linaleli: Liipone tsa teleskoupo ea sepakapaka, mojaro oa sathelaete, le lisebelisoa tsa optical tse fofang moeeng.
Tšireletso le tshireletso: Litsamaiso tsa tataiso ea IR, liipone tse shebaneng le pono ea bosiu.
Metrology e nepahetseng: Interferometry, teko ea ho batalatsa, le optics ea litšupiso bakeng sa ho lekanya.

LBH

P1: Na seipone sa SiC se bonahatsa maqhubu a bonahalang?
A1: Substrate ka boyona ha e bonahale, empa ka masela a bonahatsang a loketseng (a tšepe kapa a dielectric), liipone tse bataletseng tsa SiC li ka sebetsa ka katleho maqhubung a bonahalang, a infrared, esita le a laser.

P2: Ke melemo efe eo SiC e fanang ka yona ho feta diipone tsa khalase kapa tsa tshepe?
A2: SiC e bobebe haholo, e tiile, 'me e tsitsitse mochesong ho feta likhalase kapa li-substrate tsa tšepe. E boetse e tšoarella haholo libakeng tse thata kapa tse sepakapakeng.

P3: Na liipone tse bataletseng tsa SiC li ka sebelisoa lits'ebetsong tsa laser tse matla haholo?
A3: E. Ka ho tsamaisa mocheso hantle le botsitso ba mechini, li-substrate tsa SiC li loketse liipone tsa laser tse matla haholo kapa tse matla haholo ha li kopantsoe le lipente tse loketseng.

P4: Ke boemo bofe ba ho ba bataletseng bo ka fihlellehang?
A4: Kamora ho bentsha ka nepo e phahameng, ho batalatsa ho ka fihla ho ≤ 1 μm, ka ho bapanya le ho ba thata ha bokaholimo ho laolwa ho fihlela litlhaloso tse thata tsa mahlo.
