MeX

MeX turns any SEM into a 3D measurement device

MeX is a stand alone software package that turns any SEM with digital imaging into a true surface metrology device. Using stereoscopic images the software automatically retrieves 3D information and presents a highly accurate, robust and dense 3D dataset which is then used to perform traceable metrology examination. The results are obtained irrespective of the SEM magnification providing metrology at macro and micro levels. No additional hardware is necessary to run MeX and it can be used with any SEM. Due to the unique AutoCalibration routine the calibration data is automatically refined. Thereby only MeX enables traceable 3D measurements at any magnification in the SEM.

Height & Roughness Measurement

Profile measurement enables virtual cutting of specimen. The user defines a path on the optical image and receives the corresponding 3D profile. Roughness and contour measurements conform to recognized international EN ISO standards such as 4287/4288. The profile analysis also allows the fitting of primitives such as circles, angles or others.

 

Volume Analysis

Volume analysis calculates the volume of voids and protrusions. The measurement area is defined directly on the optical image. The volume is determined throughout the computation of a soap film model. For the 3Dboundary of the selected area MeX calculates a covering surface that behaves like a soap film.

 

Area Measurements

Area analysis provides the determination of Sa, Sq and Sz over a surface. Parameters like roughness, waviness and the fractal dimension of user defined surface patches are achieved. MeX automatically calculates the ISO conform analysis. For the visual representation of the surface a grey scale or pseudo colored depth map can be used. It is also possible to display ISO-lines to highlight depth variations.

 

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.
