Step Height Standard

Precise measurements with very high repeatability

Step height standards are used for calibration of the height scale of a wide range of surface measurement instruments, in particular stylus instruments, optical profilers, and atomic force microscopes.

DHM^® by Lyncée Tec refers to wavelengths for height measurements. By using ultrastable interferometric filters for selecting a precise wavelength band of a relatively broad spectrum laser source, DHM^® operating wavelengths are precisely controlled and perfectly stable. The height values do not depend on any calibration,  precise positioning, or repeatability of interferometric piezo-controller, neither on any motorized displacement, or confocal detection system.
