The DEKTAK IlA is an advanced surface profile measuring system which accurately measures vertical features ranging in height from 131 microns to  50 angstroms on a wide variety of substrate surfaces.
Measurements are made electromechanically by moving the sample beneath a diamond-tipped stylus. The high precision stage moves a sample beneath the stylus according to a user-programmed scan length and speed. The stylus is mechanically coupled to the core of an LVDT (Linear Variable Differential Transformer). As the stage moves the sample, the stylus rides over the sample surface. Surface variations cause the stylus to be translated vertically. Electrical signals corresponding to the stylus movement are produced as the core position of the LVDT changes respectively. An analog signal proportional to the position change is produced by the L VDT, which in turn is conditioned and converted to a digital format through a high precision, integrating analog to digital converter. The digitized signals from a single scan are stored in computer memory for display, manipulation, measurement. Stored programs that can be readily changed make the DEKTAK IIA ideal for both production and laboratory use.
The DEKTAK IlA is a microprocessor-based stylus profiler. The operating system is in permanent memory (PROM); program variables are stored in battery-powered RAM. The battery is sized to retain program data for three weeks without external power. The control console’s keyboard includes keys to control the scan head, measure the acquired data . The instrument is designed to perform routine measurements and analysis with easily remembered single keystrokes in a highly structured format. Versatility is retained for non-routine measurements and analysis by data and cursor manipulation. The DEKTAK 11A video monitor is a nine-inch monochrome CRT which displays programs and graphics. It can also be used to view the substrate either alone or with the graphics superimposed
