Fused Silica (JGS1, 2, 3)
Fused silica (FS) yog cov khoom siv dav siv nrog cov tshuaj purity siab, zoo thermal expansion yam ntxwv, qis qis ntawm refraction thiab zoo heev homogeneity. Zoo heev thermal expansion yam ntxwv yog ib qho zoo heev feature ntawm fused silica.Thaum piv rau N-BK7, UV fused silica yog pob tshab nyob rau hauv ib tug dav dav ntawm wavelengths (185 nm - 2.1 µm). Nws yog khawb tiv taus thiab nthuav tawm tsawg kawg fluorescence thaum raug wavelengths ntev tshaj 290 nm. Fused silica suav nrog qib UV thiab qib IR.

Peb lub neej ntawd siv cov khoom sib npaug Suav ntawm fused silica, feem ntau muaj peb hom fused silica hauv Suav teb: JGS1, JGS2, JGS3, lawv siv rau ntau daim ntawv thov. Thov saib cov ncauj lus kom ntxaws nram qab no raws.
JGS1 feem ntau yog siv rau optics nyob rau hauv lub UV thiab pom wavelength ntau yam. Nws yog dawb ntawm npuas thiab inclusions. Nws yog sib npaug rau Suprasil 1 & 2 thiab Corning 7980.
JGS2 feem ntau yog siv los ua lub substrate ntawm iav los yog reflectors, vim nws muaj cov npuas me me hauv. Nws yog sib npaug rau Homosil 1, 2 & 3.
JGS3 yog pob tshab nyob rau hauv lub ultraviolet, pom thiab infrared spectral cheeb tsam, tab sis nws muaj ntau npuas nyob rau hauv. Nws yog sib npaug rau Suprasil 300.
