The mention of 55%, 80%, and 10% in relation to oil seals might reflect various metrics or considerations concerning their performance and application. For example, in many mechanical systems, seals can be categorized based on their efficiency, effectiveness in preventing leakage, and their material composition. A 55% rating might refer to a baseline performance measure for standard oil seals, whereas an 80% rating could indicate high-performance seals designed for rigorous applications. On the other hand, a 10% figure could relate to the failure rate or the operating conditions under which these seals can be compromised.

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.
