AM4·series grating system

High-precision small-volume series grating ruler and reading head



Primary advantages

- AM4 series grating system is a compact grating for high dynamic precision system, single-field scanning application and low-latency subdivision processing, so that it has excellent dynamic performance.

- The AM4 series grating system is adapted to the M4 series ultra-thin stainless steel scale with a 40m grating pitch. The expansion coefficient is exactly the same as that of the substrate, and no separate temperature compensation is required.

- Corrosion-resistant, wear-resistant scale, high-strength scale, can effectively prevent the damage of the scale, making it still applicable in places with harsh environments. The scale surface is uncoated and when contaminated, the scale can be cleaned with solvents.
