Gold Mirrors - Au

Optical gold mirrors are reflective surfaces made of a thin layer of gold that is coated onto a substrate, such as glass or metal. The gold layer is extremely thin, typically just a few nanometers thick, which allows it to reflect light in the visible spectrum with high efficiency and low absorption.

The gold layer on optical mirrors is usually applied using a process called physical vapor deposition, where gold is evaporated in a vacuum and allowed to condense onto the substrate. The thickness and uniformity of the gold layer are carefully controlled during the deposition process to ensure optimal reflectivity.

One of the key properties of optical gold mirrors is their high reflectivity in the visible spectrum. This makes them ideal for use in applications where precise optical performance is required, such as in telescopes, microscopes, and laser systems. The gold layer on the mirror also provides excellent corrosion resistance, which makes them suitable for use in harsh environments.

Optical gold mirrors can be manufactured in a variety of shapes and sizes, depending on the specific application requirements. They can also be coated with other materials, such as dielectric layers, to improve their reflectivity and reduce losses due to absorption.

Overall, optical gold mirrors are a critical component in many optical systems, providing high performance and reliability in a wide range of applications.
