JGS1, JGS2, thiab JGS3 Fused Silica Optical iav Featured duab

Lus piav qhia luv luv:

"Fused Silica" lossis "Fused Quartz" uas yog amorphous theem ntawm quartz (SiO2). Thaum sib piv rau borosilicate iav, fused silica tsis muaj additives; yog li nws muaj nyob rau hauv nws daim ntawv ntshiab, SiO2. Fused silica muaj ntau dua kis tau tus mob nyob rau hauv infrared thiab ultraviolet spectrum thaum piv rau ib txwm iav. Fused silica yog tsim los ntawm melting thiab re-solidifying ultrapure SiO2. Synthetic fused silica ntawm qhov tod tes yog tsim los ntawm silicon-nplua nuj chemical precursors xws li SiCl4 uas yog gasified thiab ces oxidized nyob rau hauv ib tug H2 + O2 cua. SiO2 hmoov av tsim nyob rau hauv cov ntaub ntawv no yog fused rau silica ntawm ib tug substrate. Cov fused silica blocks raug txiav rau hauv wafers tom qab uas cov wafers thaum kawg polished.
