Incremental Linear Scale


The LF100 series is a high accuracy, high repeatability scale designed for applications on CNC machine tools where display steps of up to 0.1μm are required.

These linear scales have a thermal behaviour similar to steel or cast iron.

Accuracy grades of ±3μm or ±2μm per meter traverse are available.
