摘要：
An optical low pass filter consisting of a diffractive optical element consisting of a plurality of regions which have different imaging characteristics and are joined adjacent to one another so that the imaging characteristics are varied discontinuously. This optical low pass filter is to be used for optical instruments using solid-state image pickup devices and so on.
