NH-3N

This equipment has made complete non-contact, high precision, automatic measurement of shape, dimensions and surface roughness possible with a laser probe system. It provides multi-measurement functionality for a wide range of uses from R&D to quality control of the manufacturing line for photonic devices, semiconductor products, ultra-precision machining parts, etc. for which the market will demand smaller products with higher precision and lower costs.

Features

  • Four years after first being sold, the NH-3, which has become a byword for non-contact height measurement, has evolved into the new NH-3N, implementing feedback on the functions of the high precision NH-3 SP.
  • Experience the world of ultimate non-contact measurement which features auto focus functionality that is not affected by low reflectivity and completely non-destructive measurement, at the same time pushing the edge of precision for Z, X and Y measurements.
