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.


μCMM enables highly accurate measurements of the smallest geometric features, even on large components. The individual surface characteristics are verified with large measuring point density. Due to the high accuracy of the axis systems, these individual measurements can be precisely set in relation to each other within the entire measurement volume. A 3D measurement is only done at the relevant measuring positions and thus in a very short time. Users now have the ability to measure both surface roughness and GD&T features with tolerances in the single-digit μm range with only one measurement system.

* Each point represents a distance measurement of a specific length.
* 5 lengths, 3 times, 7 directions, according to ISO 10360-8
* Test uncertainty according to ISO 23165: U(k=2) = 0.05 μm + 0.3 μm/m (lase r interferometer)

Part of the μCMM calibration is the determination of the length measurement errors according to ISO 10360:8. In this example μCMM achieves a length measurement error of 0.3+L/600 over the entire travel distance. The difference of 0.5 μm to the accuracy specification of 0.8+L/600μm shows that the accuracy specification of the micro coordinate measuring system is chosen conservatively.
