We will describe an instrument that is developed by Canada for the James Webb Space Telescope (JWST) project. NIRISS will offer powerful imaging and spectroscopic capabilities in the near Infrared: wide-field grism spectroscopy (1-2.5 microns), single object spectroscopy (0.6-3 microns; aperture-masking interferometry with a non-redundant mask and broad-band imaging (1-5 microns). We will explore possible applications to the studies of white dwarfs such as the discovery and characterization of dusty disks around white dwarfs offered by NIRISS and the other instruments on-board JWST.
