High reflectors are optical coatings maximizing the reflectance of an optical surface in a specified spectral range. The coating performance outside of the specified spectral range is generally of no interest. High reflectors can be divided into two groups: metal coatings and dielectric coatings. Thin layers of silver, aluminum, gold provide high reflectance in a wide spectral range but they are extremely fragile and it is difficult to maintain them over long periods of time. Often metal high reflectors require a protective dielectric layer. Dielectric high reflectors can be considered as an alternative but they exhibit much narrower high reflection range.
OptiLayer provides various numerical tools for designing dielectric and metal-dielectric high reflectors. |
