Mobile, high resolution measurement

PortableRL is an optical 3D measurement system for quality assurance of micro structured surfaces. Users verify measurement fields of up to (mm) 50x50x26. The system is applied for both curved and flat components. A battery pack allows a flexible use and mobile positioning, enabling the use of the system wherever needed. A large vertical scanning range allows the measurement of various geometry types and forms. Amongst others, fields of use are platen inspection, asphalt measurement, quality assurance of turbine or rotor blades, 3D measurement of steel and body parts.

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.
