An angular-independent Solc-type electro-optical filter based on two-dimensional (2D) angularly periodically poled LiNbO3 is presented. We find that the 2D angularly poled LiNbO3 can provide invariable radial reciprocal vectors which can be used in designing angular-independent Solc-type electro-optical filter. The study demonstrates that the Solc-type filter based on 2D angularly poled LiNbO3 can keep its central passing wavelength unchanged even though the incident light deviate from the normal incidence. The angular-independent Solc-type electro-optical filter can find its application in multi-angle, multi-beam filtering.
