Isingeniso Ilensi ye-Si

Ngenxa yezici zayo zokudlulisa i-infrared ezizinzile kanye nezakhiwo zayo ezinhle kakhulu zomzimba, i-silicon isibe yinto esetshenziswa kabanzi ekwakhiweni kwe-optical okuphakathi kwe-infrared. Uma ihlanganiswa nesembozo se-IR AR esakhiwe ngokucophelela, amalensi e-silicon ahlinzeka ngesisombululo esingabizi kakhulu nesisebenza kahle kakhulu sezinhlelo zesimanje zokuthwebula izithombe ze-infrared kanye nokuzwa.

Izici Zezinto Ezibonakalayo kanye Nezinzuzo Zokusebenza I-Si Lens

I-Silicon ibonisa ukudluliswa kwe-infrared okuqhubekayo ngaphakathi1.2–8 μmububanzi bamaza futhi bufaneleka kakhulu3–5 μm (MWIR)izinhlelo zokusebenza. Izakhiwo zayo zomzimba zangaphakathi zivumela amalensi e-silicon ukuthi alondoloze ukuzinza kokukhanya kanye nokwemishini ngisho nangaphansi kwezimo zokusebenza eziyinselele.

Izinzuzo ezibalulekile zezinto ezibonakalayo zifaka:

Ukushisa okuphezulu kokushisa ukuze kuqedwe ukushisa okuphumelelayo
Amandla aqinile okusebenza ngomshini kanye nokumelana nokushaqeka kokushisa
Ubunzima obuphansi uma buqhathaniswa ne-germanium, okuvumela ukwakheka kohlelo oluncane
Ukuzinza okuhle kwemvelo kanye namakhemikhali
Ukuhambisana nezinqubo zokukhiqiza ngokunemba kwe-optical

Lezi zici zenza amalensi e-silicon abe ukukhetha okuhle kakhulu kwezinhlelo ze-infrared okumele zisebenze ngokwethembeka isikhathi eside noma ezindaweni zokushisa ezishintshashintshayo.

Ilensi ye-Si lens yomklamo we-infrared Anti-Reflection Coating Design

Ngenxa yokuthi i-silicon ine-refractive index ephezulu, izindawo ezingamboziwe zingaletha ukulahlekelwa okukhulu kokukhanya. Ukuze kulungiswe lokhu,izembozo ezilwa nokukhanya kwe-infraredzisetshenziswa ezindaweni zelensi ukuthuthukisa ukusebenza kahle kokukhanya.

Isembozo se-IR AR senzelwe ukuthi:

Nciphisa ukubonakaliswa kweFresnel ezindaweni zokuhlangana ze-silicon-air
Khulisa ukudluliswa okusebenzayo kulo lonke ibhendi ye-infrared eqondiwe
Thuthukisa ukucaca kwesithombe, ukuqhathanisa, kanye nokuzwela kokutholwa
Cindezela ukubonakaliswa okulahlekile ngaphakathi kwemihlangano ye-optical

Imiklamo yokumboza ingalungiselelwa ububanzi obuthile be-wavelength efana3–5 μm (MWIR) or 8–12 μm (LWIR), kanye nama-infrared bands enziwe ngokwezifiso achazwe yizidingo zesistimu.

Ukuklama Nokukhiqiza Okubonakalayo Ukuzivumelanisa Nezimo Ilensi ye-Si

Amalensi e-silicon infrared ane-IR AR coating atholakala ngezindlela eziningi zokubonisa ukuze asekele imiklamo yesistimu ehlukahlukene:

Amalensi e-Plano-convex, plano-concave, bi-convex, kanye ne-bi-concave
Amajiyometri ajikelezayo nangokwezifiso
Isembozo se-IR esivimbela ukubonakaliswa ohlangothini olulodwa noma oluphindwe kabili
Ukupholisha okunembile kokubukeka kwendawo elawulwayo kanye nokungaguquguquki

Izinqubo zokukhiqiza zilawulwa ngokucophelela ukuqinisekisa ukuhambisana kobude obuqondile, ukunemba kobuso, kanye nokusebenza kokubopha. Imiklamo eyenziwe ngokwezifiso isekelwa ububanzi, ukujiya, ukugoba, ukubekezelelana, kanye nemininingwane yokubopha.

Izindawo Zokufaka Isicelo

Amalensi e-silicon ane-IR anti-reflection coating avame ukusetshenziswa ku:

Izithombe ezishisayo kanye nezinhlelo zokubona nge-infrared
Amadivayisi okuthola nokulinganisa izinga lokushisa nge-infrared
Imishini yokuqapha nokuhlola yezimboni
I-infrared spectroscopy kanye nezinsimbi zelebhu
Izinhlelo zokulethwa kwe-laser ye-infrared kanye nokudlulisa okubonakalayo

Ukusebenza kwazo okulinganiselayo kanye nokuqina kwazo kuzenza zifaneleke kokubili ukusetshenziswa kwe-infrared kwezentengiselwano kanye nezimboni.
