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).

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. WebThese fixed slits are sold separately to allow customized choices based on the needs of the application. When ordering, be sure to purchase fixed slits of the same model (i.e. same size) for the input port and output port(s). …
