An infrared filter includes a substrate having a front and surface. The infrared filter includes screened ink and an optically clear medium, or dye impregnated medium. The screened ink has a front surface nearest the substrate and a back surface. The screened ink has a first index of refraction. The optically clear medium abuts at least a portion of the back surface of the screened ink. The optically clear medium has a second index of refraction that differs from the first index of refraction of the screened ink by less than a predetermined amount. The dye impregnated medium has a spectral transmission over an infrared wavelength of greater than 70% and a spectral transmission over a visible light wavelength of less than 5%, while at same time maintaining MTF performance of a vision system imaging through the filter. Methods of manufacture are also described.
