m (slits per mm)
An optical element with a periodic structure of thousands of closely spaced parallel rulings or lines that disperses light into its component spectral wavelengths.
d sin θ = m λ (m = 0, ±1, ±2, ...)
Dispersive Power

Dimensionless
A dimensionless material property measuring a prism or lens material's ability to separate different spectral wavelengths.
ω = (n_v - n_r) / (n_y - 1)
