Reflectance is a measure of how much light is reflected by a surface. For dielectric mirrors, the reflectance can be very high, often 99% or more, for specific wavelengths and incident angles. This is due to the constructive interference between the reflected light waves from the different interfaces between the dielectric layers.

Due to their high reflectance and ability to be engineered for specific wavelengths, dielectric mirrors are widely used in various optical applications. These include laser systems, where they are used to direct light, spectral filters in imaging systems, and optical instruments requiring efficient, narrowband reflectors.

Nikon objectivesexplained

In summary, the reflectance of a dielectric mirror is typically very high for the designed wavelength range and depends on multiple factors, including the number and thickness of the layers, the refractive indices, and the angle of incidence. By tailoring these parameters, dielectric mirrors can achieve near-total reflection for particular applications.

A dielectric mirror, also known as a Bragg mirror, is a type of mirror composed of multiple thin layers of dielectric material, usually deposited on a substrate. These mirrors are designed to reflect certain wavelengths of light while allowing others to pass through. The dielectric layers have different refractive indices and are stacked in such a way that they create constructive interference for particular wavelengths, leading to very high reflectance at those wavelengths.
