In addition to protecting against external contaminants, dust wiper seals also help retain lubrication within the system. By preventing dust and dirt from entering the system, these seals help reduce friction between moving parts, which can prolong the life of the equipment and reduce maintenance costs. Proper lubrication is essential for the smooth operation of hydraulic cylinders, pneumatic systems, and other machinery, and dust wiper seals play a vital role in ensuring that lubricants stay where they are needed most.

Another area where composite gratings shine is in the development of lasers and optical communication systems. By integrating composite gratings into laser cavities, engineers can achieve more stable and narrow linewidth outputs, enhancing the performance of laser systems. In optical communication, composite gratings are instrumental in dense wavelength division multiplexing (DWDM) technologies, where they help in multiplexing and demultiplexing multiple optical signals with minimal cross-talk and high precision.
