Linear encoder technology:optical encoder！

Once the decision has been made regarding incremental or absolute encoder feedback, the next consideration is whether the sensing technology should be optical or magnetic. While optical encoders have historically been the only option for resolutions below 5 microns, improvements in magnetic scale technology now allow them to achieve resolutions down to 1 micron.

Optical encoders use a light source and a photo-detector to determine position, but their use of light makes them sensitive to dirt and debris, which can disrupt the signal. The performance of optical encoders is highly influenced by the gap between the sensor and the scale, which must be properly set and maintained to ensure that signal integrity is not compromised. This means that mounting must be done carefully, and shocks and vibrations should be avoided.
