Aper\u00e7u du produit<\/strong><\/h2>\n

Les plaquettes de quartz JGS1 et JGS2 sont des substrats de silice fondue de grande puret\u00e9, principalement compos\u00e9s de dioxyde de silicium (SiO\u2082). Ces plaquettes de quartz de qualit\u00e9 optique sont largement utilis\u00e9es dans la fabrication de semi-conducteurs, les syst\u00e8mes optiques ultraviolets, les \u00e9quipements laser et les dispositifs de communication par fibre optique.\"jgs1<\/p>\n

Les plaquettes de quartz JGS1 sont produites par d\u00e9p\u00f4t chimique en phase vapeur. Cette m\u00e9thode de fabrication permet d'obtenir des niveaux d'impuret\u00e9s m\u00e9talliques extr\u00eamement bas et une tr\u00e8s faible teneur en hydroxyle, ce qui permet d'obtenir d'excellentes performances de transmission dans la r\u00e9gion de l'ultraviolet profond.<\/p>\n

Les plaquettes de quartz JGS2 sont g\u00e9n\u00e9ralement fabriqu\u00e9es \u00e0 l'aide du proc\u00e9d\u00e9 de fusion \u00e0 la flamme hydrog\u00e8ne-oxyg\u00e8ne. Par rapport au JGS1, le JGS2 contient une plus grande quantit\u00e9 d'hydroxyle mais offre des performances optiques stables dans le spectre de l'ultraviolet \u00e0 l'infrarouge proche, tout en conservant un processus de fabrication plus rentable.<\/p>\n

Les plaquettes de quartz sont disponibles dans des diam\u00e8tres allant de 2 \u00e0 12 pouces et peuvent \u00eatre personnalis\u00e9es en fonction de l'\u00e9paisseur, des exigences de polissage de la surface et des sp\u00e9cifications optiques.<\/p>\n

FAQ<\/strong><\/h1>\n

\"jgs11 Diff\u00e9rence entre les plaques de quartz JGS1 et JGS2 ?<\/h3>\n

Les plaquettes de quartz JGS1 offrent une meilleure transmission dans l'ultraviolet profond en raison de leur tr\u00e8s faible teneur en impuret\u00e9s m\u00e9talliques et en hydroxyle. Les plaquettes de quartz JGS2 offrent une performance stable de l'ultraviolet au proche infrarouge et sont g\u00e9n\u00e9ralement plus rentables pour les applications optiques standard.<\/p>\n

2 Applications typiques des plaquettes de quartz JGS1 ?<\/h3>\n

Les plaquettes de quartz JGS1 sont couramment utilis\u00e9es dans les syst\u00e8mes de lithographie dans l'ultraviolet profond, les composants optiques des lasers \u00e0 excim\u00e8re et les \u00e9quipements optiques de haute pr\u00e9cision dans l'ultraviolet.<\/p>\n

3 Applications typiques des plaquettes de quartz JGS2 ?<\/h3>\n

Les plaquettes de quartz JGS2 sont largement utilis\u00e9es dans les dispositifs de communication par fibre optique, les \u00e9quipements de traitement de l'ultraviolet et les composants optiques g\u00e9n\u00e9raux qui n\u00e9cessitent une transmission stable de l'ultraviolet au proche infrarouge.<\/p>","protected":false},"excerpt":{"rendered":"
