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).

WebNIRSpec's IFU can obtain spatially resolved imaging spectroscopy of a contiguous 3" × 3" area on the sky. To achieve this, the IFU uses specialized optics to reformat the spatial field of view and direct light to the spectrograph optics, which are shared with the multi-object spectroscopy (MOS) and fixed slits (FS) spectroscopy observing modes.

The LRS slit mode is suited to a broad range of spectroscopic observations and therefore supports a wider range of operational choices. The single slit is 4.7" long (3.18 mm; 42.7 pixels) and 0.51" wide (0.33 mm; 4.6 pixels).

WebSpectroscopic slits are narrow apertures in the optical path designed to allow light only from the intended scientific target onto the detector array. These slits are usually narrow in the dispersion direction, which limits the size of the target in the wavelength direction and improves the spectral resolution.
