Full dielectric film reflective color filter

Using the concept of a high and low refractive index material stack, the filter can be designed to reflect the selected wave domain color light in the spectrum, allowing the rest of the  wave domain color light in the spectrum to penetrate the filter. The better reflection effect can be achieved by increasing the number of film layers, or by using a quarter film stack and a half film stack design to achieve mixed color light reflected in a wide wave domain or a multi-wave domain.
