Sapphire Optical Fiber Light Transmission Extreme Environments

Lus piav qhia luv luv:

Sapphire Optical Fiber yog ib qho kev ua tau zoo ib leeg-crystal kis nruab nrab tsim rau kev siv kho qhov muag uas xav tau tshwj xeeb ua haujlwm ntev, kub tsis kam, thiab spectral stability. Ua los ntawmSynthetic sapphire (ib leeg-crystal aluminium oxide, Al₂O₃), cov fiber ntau no muab kev sib kis tau zoo ntawm qhov muag los ntawmpom rau thaj tsam nruab nrab-infrared (0.35-5.0 μm), deb tshaj qhov txwv ntawm cov tsoos silica-based fibers.

Taw qhia

Vim nwsmonocrystalline qauv, sapphire fiber ntau ua rau muaj kev tiv thaiv zoo rau tshav kub, siab, corrosion, thiab hluav taws xob. Nws ua kom ruaj khov teeb liab kis tau tus mob nyob rau hauv hnyav thiab reactive ib puag ncig uas zoo tib yam fibers yuav yaj, degrade, los yog poob pob tshab.

Cov yam ntxwv tshwj xeeb

Tsis sib xws Thermal Endurance
Sapphire optical fibers khaws cov khoom kho qhov muag thiab kev ncaj ncees txawm tias raug raukub tshaj 2000 ° C, ua rau lawv haum rau kev saib xyuas hauv qhov cub, turbines, thiab combustion chambers.
Wide Spectral Qhov rai
Cov khoom txhawb nqa lub teeb kis tau zoo los ntawm ultraviolet mus rau nruab nrab-infrared wavelengths, tso cai rau siv tau yooj yim hauvspectroscopy, pyrometry, thiab sensing applications.
High Mechanical Robustness
Cov qauv siv lead ua ib leeg muab lub zog tensile siab thiab tawg tsis kam, ua kom muaj kev ntseeg siab nyob rau hauv kev co, kev poob siab, lossis kev ntxhov siab.
Exceptional Chemical Stability
Resistant rau acids, alkalis, thiab reactive gases, sapphire fibers ua hauj lwm zoo nyob rau hauv chemically aggressive atmospheres, nrog rauoxidizing los yog txo ib puag ncig.
Radiation-Hardened Khoom
Sapphire inherently tiv thaiv kom tsaus ntuj los yog degradation nyob rau hauv ionizing hluav taws xob, ua rau nws zoo tagnrho rauaerospace, nuclear, thiab kev tiv thaivkev ua haujlwm.

Kev Siv Tshuab

Sapphire optical fibers feem ntau yog tsim los sivLaser-Heated Pedestal Loj hlob (LHPG) or Edge-defined Film-fed Growth (EFG)txoj kev. Thaum lub sij hawm kev loj hlob, ib tug sapphire noob siv lead ua yog rhuab mus rau ib tug me me molten cheeb tsam thiab ces kos upwards ntawm ib tug tswj tus nqi los tsim ib tug fiber nrog ib tug sib xws txoj kab uas hla thiab zoo meej siv lead ua orientation.
Cov txheej txheem no tshem tawm cov ciam teb thiab cov impurities, uas ua rau aTsis muaj teeb meem tsis muaj ib leeg-crystal fiber. Tom qab ntawd qhov saum npoo yog precisely polished, annealed, thiab optionally coated nrogtiv thaiv los yog reflective txheejlos txhim kho kev ua tau zoo thiab kav ntev.
