Stability of an optical monitor for deposition of 42-layer interference bandpass filter 520-590 nm
Žídek, Karel
2018 - Czech
We report on stability of a deposition process of a complex system of thin layers. The layers were designed as a 42-layer bandpass interference filter. The layers of TiO2 and SiO2 were monitored both by the means of a crystal and an optical thickness monitor. We discuss the case when the design of the interference filter is continuously adapted according to the real thickness of the already deposited layers. V této zprávě popisujeme stabilitu depozice komplikovaných soustav tenkých vrstev, které byly navrženy jako interferenční filtr s pásmovou propustností. Jde o 42 vrstev TiO2 a SiO2, které jsou monitorovány jednak tzv. krystalovým a optickým monitorem tloušťky. Diskutujeme případ, kdy je návrh IF průběžně upravován podle reálné tloušťky deponovaných vrstev.
