The dispersion angle is obtained from the wavelength (lambda) in Å, the dispersion order (m) and the lines/mm of the grating (r) as:
The resolution is then given as:
with F = effective focal length of the spectrograph, which for the Cananea Boller & CHivens is equal to 465mm. Here is a web program which calculates dispersion angle and spectral resolution using the above formulae.
