Prism material dispersion effects on the total dispersion of prism pair system

摘要

The contribution of prism material dispersion to amount of prism pairs system dispersion is discussed. It is found that the second and third order dispersion de- pend on the distance between two prisms(ι)andmotion variable(Δ).As the optical path inside prism increases, the positive dispersion increases and the negative dispersion decreases for the prism pair.
