Broadband Dielectric Mirrors

The design objective of broadband dielectric mirrors is to provide high reflectivity over a wide spectral range. When a light wave incident on the dielectric mirror, each layer interface results in reflection. These reflected waves interfere with each other, leading to enhanced reflection at specific wavelengths. By carefully choosing the types of dielectric materials and the thickness of each layer, mirrors can be designed to have very high reflectivity in certain spectral regions.broadband dielectric mirrors is that they can provide very high reflectivity (up to 99.99% or more) and a very wide reflection bandwidth. Additionally, they are typically less sensitive to environmental changes (such as temperature and humidity), making them highly desirable for a variety of industrial and scientific applications.
