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.
