We have studied the effective design of the neutron Talbot-Lau interferometer on the premise of the wavelength-resolved measurement. Based on this study, several sets of gratings have been developed for the RADEN beam line in J-PARC MLF. The performances of interferometers have been evaluated and compared with the case of using continuous beams.
