We analyze the operable angle range of the <i>c</i> axis and the incident angle of the input beam in the beam-fanning novelty filter (BFNF). With Fourier transforms we show the analysis method for the beam-fanning phenomenon. We investigate the beam-fanning phenomenon for not only the <i>c</i> axis but also the incident angle of the input beam in order to operate the BFNF sufficiently. Consequently, we clarify the angle range of the <i>c</i> axis and the incident angle, from which sufficient strong beam-fanning effect can be obtained to operate the BFNF. In addition, we verify the numerical results experimentally.
