Surface Metrology Equipment

Altimet is considered as the specialist in Surface Metrology, with prestigious International References.

Altimet as manufacturer, ensures the development, assembly, sales and maintenance of its range of instruments.


During the end of the 20th century, the study of surfaces has improved. Many areas of industrial activity are directly affected by surface metrology. The phenomena of friction, wear & tear (…) occur at the solid surface and the surface metrology play at this moment a main role in the control of mechanics components, as well as optical and electronical components.

Altisurf © range of Surface Metrology instruments combine metrology with an optical microscopy approach in a 3D mapping, with the taking of successive profiles done by scanning a point of chromatic confocal measurement or low downforce stylus.

Coming from the well-known concept of roughness in Mechanics, the deep study of “Valleys and Peaks” of the surface allows scientists and engineers to develop quality diagnostics, to functionality, aesthetics of their product or their material with a new metrological approach.

This includes new surface roughness parameters currently set up via the work of standards committees the new 3D measurement norm ISO 25 178 within the ISO International.


Altisurf Is Divided Into Different Models


With the AltiSurf© 50, you can measure samples without contact wherever you want thanks to its integrated optical sensor. This measuring profilometer, also integrable on marble in a laboratory, can easily be transported to measure in the workshop near the line or on very large parts.

Our embedded machine has found its applications in engraving measurement,texturing, polished or micro-structured surface states especially in watchmaking industries, fiduciary and laser engraving.

With the measurement mobility in workshop environment, sometimes 6 meters height in the line, with centering rollers cured to 200 ° C.

It is also compatible with many lining for an easier use.
