Spectral Resolution

(R, Resolution)
(measure of a spectrograph's ability to resolve features of the spectrum)

Spectral Resolution is a measure of a Spectrograph's ability to distinguish features in the spectrum, typically noted as ΔΛ, meaning the smallest division in Wavelengths that the spectrograph can distinguish.

The Resolving Power is defined as:

    λ
R = ——
    Δλ
