Optical linear encoders dominate the high resolution market compared to other types of linear encoders, e.g. magnetic, capacitive, and inductive ones. This is because optical linear encoders are advantageous in terms of measuring range, precision and response speed.

Phase gratings are one of the most important parts in optical linear encoders. As a position sensor with very high resolution, an optical linear encoder usually uses infrared LED, visible LED, small light bulbs or diode laser as its light source. They are widely used in various lathes, machining centers, automation equipment, and measuring devices. They can used in either linear or rotary way. The precision ranges from several hundred microns to submicron or even as small as one nanometer.

Optical linear encoders are essential parts in modern industry. They not only represent a high precision, but also significantly improve the productivity.
