We developed an unprecedented optical filter which has a luminous efficiency filtering function and an optical low pass filtering function for the downsizing of CCD camera optics. The filter was made of synthetic resin and it had phase grating on its surface. The light transmittance and the optical low-pass function of the new filter which had a 1 mm thickness were a little different from those of a conventional quartz device which had a thickness of more than 3 mm. We discuss the characteristics of and the production processes for the developed filter in this paper.
