The ultra-stable SP-DI laser interferometers can be used both for long-term measurements in research and development, e.g. for material analyses, and in compact design (SP-DI/F) as feedback sensors for positioning systems in industrial environments. They are characterized by a unique thermal stability of less than 10 nm/K.
The SP 15000 C5 calibration laser interferometer was developed to meet the requirements of machine and equipment manufacturers. Length, angle and straightness can be measured simultaneously with high accuracy. Due to the compact straightness option, the setup and adjustment of the measuring systems is very easy and quick, even in confined spaces. Straightness can be measured over a length of 6.5 meters.
