Abstract: An optical filter and a matching composite layer thereof are provided. The matching composite layer includes a plurality of first refraction layers, a plurality of second refraction layers, and a plurality of third refraction layers. A refractive index of the second refraction layer is greater than that of the first refraction layer, and is less than that of the third refraction layer. Any two of the second refraction layers provided with one of the first refraction layers sandwiched there-between are sandwiched between two of the third refraction layers so as to be jointly defined as a bidirectional incremental module. A number of the bidirectional incremental module included in the matching composite layer is at least M, where M is a positive integer greater than three. The M number of the bidirectional incremental modules are stacked and connected with each other.
