Fixed slit spectroscopy
WebMOS is an efficient way to obtain the spectra of many sources all within the field of view (FOV) of an instrument at a single pointing. This can also be accomplished using a wide field slitless spectroscopy capability (WFSS) like that offered with the NIRISS and NIRCam instruments. To compare and contrast MOS spectroscopy and wide field ... 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).

In order to achieve the scientific objectives NIRSpec has four operational modes: Multi-Object Spectroscopy (MOS) In MOS the total instrument field of view of 3 × 3 arcminutes is covered using 4 arrays of programmable slit masks. These programmable slit masks consist of 250 000 micro shutters where each can individually be programmed to 'open' or 'closed'. The contrast between an 'open' or 'closed' shutter is better than 1:2000. If an object like e.g. a galax…
