20nm High-precision and Highly Anti Pollution Open Type Grating Scale System
Product Description
Grating scale incremental linear scale:
RUS grating ruler is an incremental 2um grating ruler designed to provide feedback for high precision linear measurement. It adopts LAMOTION's most advanced interference grating line marking technology, and the grating line error is controlled below 40nm. It uses high strength, corrosion-resistant special stainless steel to ensure long-term stable use.
RUS High Precision Stainless Steel Gate Ruler is made of high precision, super hard, high elasticity and corrosion resistant special substrates.Excellent mechanical and chemical properties of the substrate ensure its long-term stability and reliability;RUS high-precision stainless steel grating ruler uses advanced marking technology to achieve fine marking of 20 micron spacing grating lines, and ensures the accuracy of less than 40 nanometers, +5 um/m, the ruler has its own backing glue, and can be quickly installed by sticker tool.
--High Precision: +5um/m --Low expansion coefficient: 10.5um/m/~C
--High linearity: +2.5um/m --Fast Installation: Provide tape tool, tape tape with back glue
--Small size: 0.2mm thick * 8mm wide --Excellent materials: corrosion resistance, high hardness
--Ultra Long Size: 50m Ultra Long Order Length
