Continuous ND filters are fabricated on the silver halide photoplates. These filters enable us to get intensity modulated laser beam. Two kinds of continuous ND filters are fabricated. Optical density of one filter is increased radically and that of the other is decreased. In order to get a filter having desirable optical density, a mask which has reversed optical density has to be made. made.
