Description: Bruker DektakXT is a stylus profilometer capable of measuring 55 mm in a single scan and 3D mapping of area up to 200 mm x 200 mm with stitching. Stage configuration allows for automated X, Y, and rotation along the stage’s normal vector. Stylus measuring range (z) is up to 1 mm with a minimum resolution of 15 nm. Stages fixtures are interchangeable: vacuum table for 8-inch) wafers and 150 mm x 150 mm microporous ceramic vacuum table are available.
