Dektak® stylus profilers provide accurate, high resolution measurement of surface shape and texture. The heart of a Dektak system is its measurement stylus, which runs over the surface as the sample is moved beneath it on the stage. A variety of stylus shapes and sizes are available to optimize measurement for particular applications. This paper describes the variety of styli that are currently available from Veeco, and guidelines for choosing the optimal tips for your application. Dektak150 表面輪廓儀（臺(tái)階儀）
