The document describes a high resolution instrument called the Form Talysurf i-Series that can perform both surface finish and contour measurement simultaneously. It has a high resolution gauge with a range of up to 5mm and resolution down to 0.4nm, ensuring accurate measurement. The instrument also has low noise axes, temperature compensation for consistent performance, and algorithms that eliminate instrument influence from results. It can measure roughness, waviness, contour, and perform 3D analysis with optional upgrades, making it suitable for applications like automotive and bearings.
