Techniques are described to furnish an IR suppression filter, or any other interference based filter, that is formed on a transparent substrate to a light sensor. In one or more implementations, a light sensor includes a substrate having a surface. One or more photodetectors are formed in the substrate. The photodetectors are configured to detect light and provide a signal in response thereto. An IR suppression filter configured to block infrared light from reaching the surface is formed on a transparent substrate. The light sensor may also include a plurality of color pass filters disposed over the surface. The color pass filters are configured to filter visible light to pass light in a limited spectrum of wavelengths to the one or more photodetectors. A buffer layer is disposed over the surface and configured to encapsulate the plurality of color pass filters and adhesion layer.
