Why Gold Coating Remains Irreplaceable?

In optical drawings and purchase specifications, the term “Gold Coated” is often highlighted as a standalone requirement. At first glance, it may appear to be a premium or even conservative choice. In practice, however, gold coatings are specified not because they are expensive, but because they solve a set of engineering problems that few other materials can address simultaneously.
