High precision of the grid spacing is essential for linear thermal expansion. Measuring lengths of up to 30 m, an accuracy class of up to ± 1 µm and a resolution of 0.1 µm are features of these systems. In addition, the certificate of metrological verification is supplied with each length measuring system.
Optical length measuring systems are manufactured in accordance with strict quality standards and offered in seven different models. Product documentation, available upon request, emphasizes the high quality and reliability.
With absolute measurement, you get immediately readable mass, while incremental encoders only indicate differences. Therefore, incremental measurement requires a reference point.
Optical length measurement is an essential method for the precise determination of lengths in various industries. This technology uses light and optical elements for accurate measurements.
A great advantage of optical length measurements is that they are non-contact, which minimizes wear and protects sensitive surfaces. Therefore, they are ideal for sensitive materials.
The basis of optical length measurements is the interference of light. A beam splitter directs light onto a test surface and a reference mirror. Then the resulting interference patterns are measured.
High-precision optical linear encoders accurately measure lengths down to nanometers. This accuracy enables quality control in microelectronics, precision manufacturing and other demanding areas.
Optical length measurements are not affected by strong vibrations or extreme temperatures. This extends their range of applications and increases their reliability.
The integration of computers enables automated optical length measurements, which increases efficiency and precision. Measurement data can be digitally recorded and analyzed.
The measurement results of optical length measurements are often displayed in real time and can be directly integrated into control systems. As a result, they enable fast feedback and adjustments.
Optical length measurements are used in areas such as manufacturing, quality control, research and development. They contribute to product improvement and process optimization.
However, setting up and calibrating optical length measurement systems requires specialized knowledge. Accurate calibration is critical to ensure precise measurement results.
Overall, optical length measurements offer high precision and flexibility to enable accurate length measurements in a wide range of applications.
