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. 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.

WebThe JWST IFUs. JWST has 2 IFUs: the MIRI medium resolution spectrometer (MRS) provides R ~ 1,500–3,500 spectroscopy from wavelengths of 4.9 to 27.9 μm over a contiguous field of view up to 6.6'' × 7.7'' in size, while NIRSpec provides R ~ 100, 1,000, and 2,700 spectroscopy from 0.6 to 5.3 μm over a contiguous field of view 3" × 3" in size. WebThe fixed slits are always open and, therefore always appear in MSA science mode exposures. Pointers also show zero-order images of the right spectral slitlets—these zero-order slit images are seen in the medium resolution (R ~ 1,000) spectral configurations and appear on detector NRS1.
