spectral resolution
  واگشود ِ بیناب، ~ بینابی  
vâgošud-e binâb, ~ binâbi
Fr.: résolution spectrale  

The capacity of a spectrograph to separate two adjacent spectral lines. The theoretical spectral resolution depends on the grating dispersion, grating position, pixel size, collimator and camera focal length, and the entrance slit-width.
