What is the thickness and micro-roughness of the SCHOTT Nexterion® Slide H coating?
The coating on Nexterion® Slide H has been measured using atomic force microscopy (AFM) and ellipsometry. As the coating swells in the presence of water it has been measured in both the dehydrated and hydrated state. The dehydrated Nexterion® Slide H coating is approximately 10 – 20 nm thick with a peak-to-trough roughness of less than 1 nm (rms roughness = 0.29 nm), similar to the surface of the underlying glass. After 30 minutes hydration, the film thickness stabilizes at 50 – 100 nm, and has a final peak-to-trough roughness of approximately 10 – 20 nm (rms roughness = 3.20 nm).
