Product DescriptionFeatures & SpecificationsDelivery & Returns
The 240AC-FG with a carbon nanofiber at the end of the silicon tip is designed for soft AC mode AFM imaging of deep trenches. The typical fiber radius of curvature is 10nm and the diameter is 50nm at a height of 200nm away from the apex.The gold coating ensures high and stable laser reflectivity in air and liquids. The tetrahedral tip is located precisely at the free end of the cantilever. This allows the tip to be positioned accurately over the area of interest on the sample surface. Please note that while the tetrahedral tip and the tip side of the cantilever are gold coated, the diamond-like spike remains uncoated.
