The new µCMM

Measure components with extremely tight tolerances in high accuracy

μCMM is the most accurate purely optical micro-coordinate measuring system in its class. Users combine advantages from tactile coordinate measuring technology and optical surface measuring technology and measure the dimension, position, shape and roughness of components with only one sensor. The optical CMM offers high geometric accuracy of several optical 3D measurements in relation to each other, enabling the measurement of small surface details on large components and precisely determining the position of these individual measurements in relation to each other. The spectrum of measurable surfaces includes all common industrial materials and composites such as plastics, PCD, CFRP, ceramics, chrome, silicon. Materials from matte to polished, reflective components can be measured. Simple operation is implemented by single-button solutions, automation and ergonomic control elements such as a specially designed controller. Air-bearing axes with linear drive enable wear-free use and highly accurate, fast measurements. This makes μCMM ideal for permanent use in production, too.

Intuitive usability, designed for multiple users

The spectrum of measurable surfaces is largely material-independent and includes all materials and composites commonly used in the industry, from matte to polished or mirrored components.

Dense non-contact and material-independent measurement

Alicona measurement systems offer the functionalities of a surface- as well as a coordinate measurement system combined into one system. As a result, your quality assurance becomes more cost effective, is easier to execute and delivers results more efficiently.

Wear-free and
efficient use

All components, including the moving axes, operate contact-free. Air-bearing linear drive axes enable wear-free operation and highprecision, fast measurement. This makes μCMM ideal for permanent use in production.

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.
