Lenska silikon dahaarka leh ee monocrystalline silikoon caado dahaar leh oo dahaarka leh filim lidka-milicsiga AR

Lenska silikoon ee dahaarka leh ee monocrystalline silikoon caado dahaar leh AR-ka-hortagga filimka Sawirka leh

Sharaxaad Gaaban:

lenska silikoon monocrystalline dahaarka leh waa curiye indhaha ah oo shaqaynaya oo ku salaysan nadiifnimo sare oo monocrystalline silicon (Si) iyadoo la adeegsanayo farsamaynta indhaha ee saxda ah iyo tignoolajiyada daahan. Silicon Monocrystalline waxay leedahay gudbinta iftiinka aad u fiican ee infrared band (1.2-7μm), oo ay weheliso dahaarka sida filimka lidka-milicsiga (AR), filimka sare ee milicsiga (HR) ama filimka filter, waxay si weyn u wanaajin kartaa gudbinta ama waxqabadka milicsiga ee kooxo gaar ah. Alaabooyinka waxaa si weyn loogu isticmaalaa imaging infrared, laser optics iyo ogaanshaha semiconductor.

Tilmaamaha lenska silikoon ee dahaaran:

1. Waxqabadka indhaha:
Qiyaasta gudbinta: 1.2-7μm (u dhow infrared ilaa dhexe-infrared), gudbinta> 90% ee 3-5μm daaqada atmospheric band (daahan ka dib).
Sababta oo ah tusmada dib u soo celinta sare (n≈ 3.4@4μm), filim lidka-milicsiga (sida MgF₂/Y₂O₃) waa in lagu dhejiyaa si loo yareeyo luminta milicsiga dusha sare.

2. Degganaanshaha kulaylka:
Isku xidhka ballaarinta kulaylka hooseeya (2.6 × 10⁻⁶ / K), iska caabin heerkul sarreeya (heerkulka shaqeynaya ilaa 500 ℃), oo ku habboon codsiyada laysarka awoodda sare leh.

3. Guryaha makaanikada:
Mohs engegnaanta 7, caabbinta xoqan, laakiin jajabnaanta sare, waxay u baahan tahay ilaalinta geesaha.

4. Tilmaamaha dahaarka:
Customized anti-reflection film (AR@3-5μm), high reflection film (HR@10.6μm for CO₂ laser), bandpass filter film, etc.

Codsiyada lenska silikoon ee dahaaran:

(1) Nidaamka sawirka kulaylka infrared
Sida qayb muhiim ah oo ka mid ah lenses infrared (3-5μm ama 8-12μm band) ee la socodka ammaanka, kormeerka warshadaha iyo qalabka habeen aragga military.

(2) Nidaamka indhaha ee laser
CO₂ Laser (10.6μm): Muraayadaha muraayadaha sare ee resonators laser ama isteerinka iftiinka.

Fiber laser (1.5-2μm): Leniska filimka ka-hortagga wuxuu hagaajiyaa waxtarka isku-xidhka.

(3) Qalabka tijaabada Semiconductor
Ujeeddada microscopic infrared ee ogaanshaha cilladda wafer, u adkaysata daxalka balaasmaha (ilaalinta dahaarka gaarka ah ayaa loo baahan yahay).

(4) Qalabka falanqaynta indhaha
Iyada oo ah qayb muuqaal ah oo ah Fourier infrared spectrometer (FTIR), gudbinta sare iyo qalloocinta xagasha hoose ayaa loo baahan yahay.

Qiyaasaha farsamada:

Lenska silikon monocrystalline ee dahaarka leh wuxuu noqday qayb muhiim ah oo aan la bedeli karin oo ku jira nidaamka indhaha ee infrared sababtoo ah gudbinta iftiinka infrared ee aad u fiican, xasilloonida kuleylka sare iyo sifooyinka daahan la beddeli karo. Adeegyadayada gaarka ah waxay xaqiijinayaan waxqabadka ugu fiican ee muraayadaha leysarka, kormeerka iyo codsiyada sawirka.

Adeegga gaarka ah ee XKH

XKH waxay bixisaa habayn buuxda oo ah muraayadaha silikoon monocrystalline ee dahaarka leh: Laga soo bilaabo xulashada substrate silicon monocrystalline (iska caabin> 1000Ω · cm), farsamaynta saxda ah ee indhaha (spherical / aspherical, saxnaanta dusha λ / 4 @ 633nm), dahaarka caadada ah (ka-hortagga-milicsiga / milicsiga sare / filimka shaandhaynta, taageerada tijaabada adag ee naqshadaynta deegaanka), tijaabinta tayada kala duwan dufcad yar (10 xabo) ilaa wax soo saar ballaaran. Waxa kale oo ay bixisaa dukumeenti farsameed (curyaaminta dahaarka, xuduudaha indhaha) iyo taageerada iibka ka dib si loo daboolo shuruudaha baahida ah ee nidaamyada indhaha ee infrared.
