Linear Scale！

The grating, also known as the grating displacement sensor (grating sensor), is a measuring feedback device that utilizes the optical principle of the grating. Raster is often used in closed-loop servo systems for CNC machines and can be used for linear displacement or angular displacement detection. The measurement of the output signal for the digital pulse, with a large detection range, high detection accuracy, fast response characteristics. For example, in CNC machine tools are often used to detect the coordinates of the tool and the workpiece to observe and track the tool error to play a role in compensating the movement error of the tool.
The grating is divided into transmission grating and reflection grating according to the manufacturing method and the optical principle.
