Dalian Rongshu Optics Co., Ltd was established in 2014, a professional enterprise that develops and produces open optical scale in china. we committed to the research, development, and production of high-precision position feedback products. There are multiple production lines for reading heads, metal grating etching and glass grating. Our products have been widely applied in domestic semiconductor industry, automation industry, high-end printing equipment field, digital medical field ,etc. We have earned the recognition and trust of our customers.
For linear position feedback, the highest precision: 5um/m, resolution up to 10nm
The rotary optical encoder is fitted with excellent accuracy and has a conical mounting system that reduces the need for machined parts with high tolerances and eliminates eccentricity. Accuracy up to 2 arcseconds, maximum diameter up to 300mm.
Non-contact opitical encoder system:lncremental linear optical encoder、Incremental Rotary optical encoder Absolute linear optical encoder、 Absolute rotary optical encoder、 Interferometric laser scale,etc.
