IF-Profiler | Optical profiler for roughness & finish

Optical profiler for roughness & finish


IF-Profiler is a handheld 3D roughness measurement system for high resolution measurement of surface finish. Users measure roughness of flat and curved components with only one system. Measurements are performed both profile based (ISO 4287) and areal based (ISO 25178). The lightweight IF-Profiler consists of a 3D measurement sensor and a robust, at the same time handy framework. The ergonomic design combines ease of use and required mechanical rigidity. Traceable and repeatable measurements are achieved in a min. measurement time of three seconds.

High measuring point density

Up to 500 million measurement points ensure a meticulously detailed measurement with tolerances in the μm and sub-μm range along with large working distance. The high measurement point density of Focus-Variation enables operators to gain a consistently high lateral and vertical resolution across high measurement volumes.

Measurement of steep flanks

Light coming from different directions is used to positively influence a measurement. The measurement of the maximum flank angle is not restricted by the numerical aperture of an objective. Depending on the surface users measure surfaces with slope angles up to 87°.

Varying surface reflections

SmartFlash allows high resolution measurements of materials with varying surface characteristics or reflectivity. Modulated light provides optimal illumination throughout the whole measurement area. Users measure glossy, ground, rough, reflective and diffuse components.

Focus-Variation Technology

Alicona measurement systems are based on the technology of Focus-Variation and combine the functionalities of a surface roughness measurement device and a form measurement system. Each Alicona measurement instrument is a surface measurement device, surface roughness measurement system, 3D measurement system for geometrical tolerancing and micro coordinate measurement system. The Focus-Variation technology combines the small depth of focus of an optical system with vertical scanning to provide topographical and color information from the variation of focus. The main component of the system is a precision optics containing various lens systems that can be equipped with different objectives, allowing measurements with different resolution.
