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.
WebThe slit and slitless modes have some operational differences. 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). WebThere are 10 first-order gratings available for long-slit spectroscopy, providing resolving powers of ~500–17,000 from the UV at 1150 Å through the NIR at ~10,000 Å.

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. real chase bank checksSlitless 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.
