Optical filter and method of forming the same |
| abstract |
The embodiment of the invention provides an optical filter and a forming method thereof. The optical filter includes a substrate and a plurality of filter stacks formed on the substrate. Each filter stack includes a high index layer, a medium index layer, and a low index layer. The high refractive index layer has a first refractive index higher than 3.5. The medium refractive index layer is disposed on the high refractive index layer. The middle refractive index layer has a second refractive index higher than 2.9 and lower than the first refractive index. The low refractive index layer is disposed on the middle refractive index layer. The low refractive index layer has a third refractive index, and the third refractive index is lower than the second refractive index. |
