Slitless spectroscopy is astronomical spectroscopy done without a small slit to allow only light from a small region to be diffracted. It works best in sparsely populated fields, as it spreads each point source out into its spectrum, and crowded fields will be too confused to be useful. It also faces the problem … See more • Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph (JWST component) • Echelle grating See more • Spradley, Joseph L. (September 1990).
