Incremental Optical Linear Scale with 20μm Resolution
Open-Type Steel Gate Ruler for Measuring Instruments
Product Overview
The RUS grating ruler is an incremental 20μm grating ruler designed to provide feedback for high precision linear measurement. It utilizes UNIMETRO's advanced interference grating line marking technology, with grating line error controlled below 40 nm. Constructed from high-strength, corrosion-resistant special stainless steel to ensure long-term stable performance.
