Puterea de rezolvare ^[1] este o cantitate care cuantifică „capacitatea” unui spectroscop de a distinge două linii spectrale cu valori de energie foarte apropiate. Este definit ca:

unde Ea și Eb sunt valorile energetice ale celor două linii spectrale. Puterea de rezolvare este, de asemenea, exprimată cu cel mai mic unghi absolut care poate fi rezolvat. ^[2]
