Manufactured with two H-shaped lapped parallel surfaces to ensure stability and lightness. The three levels of tolerances are shown in the table. The parallelism tolerance is equal to the flatness. Side faces ground (± 20 µm/m). If required, they can be supplied with handles on the heads and wooden case.

Microplan® Test Report included.

Nanoline Alumina high precision instruments

In the field of metrology, the search for new materials with improved mechanical and physical characteristics led to the use of ceramics for the manufacture of certain instruments.

The Alumina (Al2O3) produced by the Microplan® Group has technical characteristics suitable for metrology, such as dimensional stability, hardness, low expansion coefficient and an excellent modulus of elasticity.

The instruments of Nanoline Alumina series are an alternative, cost effective, compared to the same products in silicon carbide Si-sic, having very similar characteristics.
