Customized Sapphire Optical Windows High Purity Transmittance ≥90%

Lus piav qhia luv luv:

Sapphire kho qhov muag qhov rais yog cov khoom siv kho qhov muag tshwj xeeb uas tsim los ntawm ib leeg-crystal aluminium oxide (Al₂O₃), muaj npe nrov rau lawv qhov kev ua tau zoo kho qhov muag, lub zog txhua yam, thiab tshuaj lom neeg ruaj khov. Raws li qhov nyuaj tshaj plaws oxide siv lead ua (Mohs hardness 9), sapphire qhov rais nthuav tawm cov kev xa tawm zoo heev (~ 83-85% uncoated) hla ultraviolet (200nm) mus rau nruab nrab-infrared (5.5μm) spectra, ua rau lawv zoo tagnrho rau kev thov cov ntawv thov uas xav tau ob qho tib si siab transparency thiab durability.

Kev tsim khoom muaj cov txheej txheem tseem ceeb xws li siv lead ua orientation kev loj hlob, precision dicing, nanoscale polishing, thiab txheej tshwj xeeb. Cov txheej txheem kev loj hlob siab tshaj plaws (piv txwv li, HEM lossis KY txoj kev) tau txais txiaj ntsig zoo boules nrog qhov tsis xws luag (<10⁴ / cm²). Cov qauv siv lead ua hexagonal tshwj xeeb tso cai rau cov khoom siv anisotropic, nrog rau kev pom zoo (C-axis, A-axis, lossis R-dav hlau txiav) tailoring optical kev ua tau zoo rau cov kev siv tshwj xeeb.

Cov yam ntxwv tseem ceeb

1.Extreme Environment Adaptability
Sapphire optical windows qhia tau tshwj xeeb kev ua tau zoo nrog lub melting point ntawm 2053 ° C, tswj cov txheej txheem kev ncaj ncees nyob rau hauv tas li 1000 ° C kev khiav hauj lwm ib puag ncig. Qhov no thermal stability yog enabled los ntawm ib tug ultra-low coefficient ntawm thermal expansion (CTE) ntawm 5.3 × 10⁻⁶ / K raws C-axis, ho superior rau cov pa tsom iav qhov muag. Chemically, sapphire kho qhov muag qhov rais muaj qhov zoo tshaj plaws inertness, tiv thaiv tag nrho cov acids muaj zog (tshwj tsis yog HF) thiab alkalis, ua rau lawv zoo tagnrho rau cov khoom siv tshuaj thiab kev siv marine. Mechanically, cov qhov rais no khav theeb flexural zog tshaj 1000MPa (5-8 lub sij hawm muaj zog tshaj tus qauv kho qhov muag iav) nrog zoo heev cuam tshuam.

2.Optical Performance Advantages
Sapphire optical qhov rais muab> 80% kis tau tus mob thoob plaws ntau yam spectral (200-5500nm ntawm 2mm thickness). Los ntawm optimized siv lead ua orientation (xws li, C-axis perpendicular mus rau lub teeb txoj kev), cov teebmeem birefringence yog zoo txo. Nto zoo ua tau raws li qhov yuav tsum tau kho qhov muag nruj nrog λ / 10 flatness ntawm 633nm thiab nto roughness <0.5nm RMS.

3.Advanced Manufacturing Peev Xwm
Peb lub qhov rais sapphire kho qhov muag txhawb kev ua haujlwm loj (> 300mm txoj kab uas hla) thiab cov geometries nyuaj xws li aspheric thiab stepped configurations. Tshwj xeeb ntug sealing tshuab ua tiav cov nqi xau <1 × 10⁻⁹P·m³ / s rau kev siv lub tshuab nqus tsev. Nrog pob zeb diamond zoo li cov pa roj carbon (DLC) txheej, lub laser-induced kev puas tsuaj pib (LIDT) ncav cuag 15J / cm² (1064nm, 10ns pulses).
