Amacala okusetshenziswa ajwayelekile
- Umkhiqizi wesihlungi sesiteshi se-5G usebenzisa i-Ta₂O₅ yezinga le-elekthronikhi, okunciphisa ukulahlekelwa kokufakwa kube yi-1.2dB (ibhendi ye-3.5GHz)
- High-end camera lens manufacturers use optical-grade products to achieve a refractive index of nd=2.15@587.6nm
Izinto okufanele uziqaphele
• Ukuphathwa kwempuphu ye-nano kumele kuhambisane nezindinganiso zokuvikela ukuphefumula ze-ISO 13137
• Kunconywa izitsha zokubhaka ze-Corundum ukuze kusetshenziswe ukushisa okuphezulu
• Izimbozo ezibonakalayo zidinga ukulawula izinga lokufakwa kwe-deposit libe ngaphansi kuka-0.5nm/s
