By analogy with optical observations, ''e.g.'' in astronomy, the term [[optical resolution]] in [[structure determination]], <math>d_\mathrm{opt}</math>, is used to describe the expected minimum distance between two resolved peaks in an electron-density map.

<math>d_\mathrm{opt} = [2(\sigma_\mathrm{Patt}^2 + \sigma_\mathrm{sph}^2)]^{1/2}</math>

where <math>\sigma_\mathrm{Patt}</math> is the standard deviation of the Gaussian function fitted to the Patterson origin peak, <math>\sigma_\mathrm{sph}</math> is the standard deviation of the Gaussian function fitted to the origin peak of the spherical interference function, representing the Fourier transform of a sphere with radius <math>1/d_\mathrm{min}</math>, and <math>d_\mathrm{min}</math> is the nominal [[resolution]].

The term was introduced into the protein structure determination literature by Vaguine, A. A., Richelle, J. & Wodak, S. J. [(1999).
