Focus-Variation combines the small depth of focus of an optical system with vertical scanning to provide topographical and colour information from the variation of focus. The main component of the system is a precision optic containing various lens systems that can be equipped with different objectives, allowing measurements with different resolution.
The Alicona operates with proprietary MeasureSuite software which also allows for quantification of surface roughness and measurement of profile features.
