Optical filters and methods for forming the same
An optical filter and a method for forming the same are provided. The optical filter includes a substrate and a plurality of filter stacks formed on the substrate. Each of the plurality of filter stacks includes a higher-refractive-index layer, a medium-refractive-index layer, and a lower-refractive-index layer. The higher-refractive-index layer has a first refractive index of higher than 3.5. The medium-refractive-index layer is disposed on the higher-refractive-index layer. The medium-refractive-index layer has a second refractive index higher than 2.9 and lower than the first refractive index. The lower-refractive-index layer is disposed on the medium-refractive-index layer. The lower-refractive-index layer has a third refractive index lower than the second refractive index.
