Laser Interferometer
Coming soon: FDM-3 with sub-nanometer resolution
The FDM-3 laser interferometer from fionec offers up to three compact and lightweight measurement heads, making it ideal for integration as control interferometers. With measuring distances of up to one meter per measurement head, most length measurements in the production environment can be optimally addressed. Thanks to a high measuring frequency of 40 kHz, integrated interfaces and customized software solutions, a complete and straightforward integration into existing systems is possible. The laser interferometer impresses with an attractive price-performance ratio, without compromising on measurement resolution.
