Guangzhou Lokshun CNC Equipment Co.,Ltd., started from Guangzhou Sino Digital Readout Co.,Ltd., founded in August 2002. It is a private hi-tech company engaged in developing, researching and manufacturing CNC equipment. It produces product series including linear displacement sensors, encoder digital displays and encoders. 
广州市诺信数字测控设备有限公司，发展始于广州市信和光栅数显有限公司，成立于2002年8月，是一家专业开发、研制、生产数控装备制造业的民营高科技公司，专门生产光栅线位移传感器、光栅数显表和编码器等一系列产品。

Starting from Taiwan, Rational Precision Instrument Co., Ltd., was set up in Guangdong, China in 1995, and is now a professional company in precise measuring field. With the R&amp;D force from both Taiwan and mainland China, Rational has been a successful high-tech company by dedicating to innovation and manufacturing for measuring systems. Rational has been highly focused on precise and high resolution measuring equipment and is a leading supplier of varieties of measuring systems or devices such as Digital Measuring Projectors, Video Measuring Systems and Linear Scales in China and Asia. With the state of the art technology, which integrates optics, machinery, electronics and software engineering, Rational has won outstanding reputation in precision measuring field. We have been awarded main titles of good reputation and honored enterprises in Guangdong province, China for many years and are ISO9001-2015 and CE certified.

Rational Digital Read-Out (DRO) 万濠光栅

A digital readout (DRO) is a numeric display, usually with an integrated keyboard and some means of numeric representation. Its integral computer reads signals generated by <a href="https://en.wikipedia.org/wiki/Linear_encoder" target="_self">linear encoders</a> or (less frequently) <a href="https://en.wikipedia.org/wiki/Rotary_encoder" target="_self">rotary encoders</a> installed to track machine axes, using these measures to keep track of and display to a machine operator the workpiece position (e.g., milling machines), or tool position (lathes, grinders, etc) in space. 
由大量等宽等间距的平行狭缝构成的光学器件称为光栅（grating）。一般常用的光栅是在玻璃片上刻出大量平行刻痕制成，刻痕为不透光部分，两刻痕之间的光滑部分可以透光，相当于一狭缝。精制的光栅，在1cm宽度内刻有几千条乃至上万条刻痕。这种利用透射光<a href="https://baike.baidu.com/item/%E8%A1%8D%E5%B0%84/1084873" target="_blank">衍射</a>的光栅称为透射光栅，还有利用两刻痕间的反射光衍射的光栅，如在镀有金属层的表面上刻出许多平行刻痕，两刻痕间的光滑金属面可以反射光，这种光栅称为反射光栅。
