Couple of V-prisms ideal for testing cylinders. The tolerances expressed in the table (in micrometers) refer to flatness of the base, and parallelism between the base and the axis of the V-slot. On request, other faces can be lapped.

Nanoline Alumina high precision instruments

In the field of measuring instruments, 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 tools ofNanoline Aluminaserie are an alternative, cost-effective, compared to the same products in silicon carbide Si-sic, despite having very similar characteristics.
