The Gemini surface topography instrument combines the Vista large sample AFM and the Horizon non-contact optical profiler to provide direct 3-D measurements from the millimeter to the angstrom level. The Vista offers contact, AC, phase and lateral force imaging modes with an optional scanning tunneling mode. The Horizon offers the capability to measure areas as large as 2 x 2 mm with a Z range of 100 microns, while also providing vertical resolution to the angstrom level. The Gemini measures topographic features as well as surface roughness, friction and compliance.
