HPI-3D Laser Interferometer

HPI-3D is a high-precision laser interferometric system designed for measuring linear displacement, vibrations, angles, and machine geometry, as well as for calibrating CNC machines, CMMs, and measurement systems. It is the result of more than 20 years of experience in laser interferometer development and combines high performance, versatility, ease of use, and a compact design.

The system is suitable for use in production environments, mechanical engineering, maintenance operations, and laboratories. Thanks to wireless connectivity, a wide range of optical components, and compatibility with PC, tablet, or smartphone operation, HPI-3D provides maximum flexibility in real-world applications.
