Burleighs Horizon profilometer uses optical interferometric technology to nondestructively measure disk surface topography

Burleigh`s Horizon profilometer uses optical interferometric technology to nondestructively measure disk surface topography. The Horizon has two modes: Smooth mode can measure roughness from the angstrom to the micron level on smooth and polished surfaces, while texture mode extends the vertical range to 100 mm, enabling measurement of rougher surfaces and steps. In a 16.5 by 12 by 22-inch footprint, the tool has a scan speed of 1.1 mm/sec at 480 by 480 pixels and a vertical range of 0.1 nm to 100 mm.
