A Fresnel Prism has a linear structure with constant prism and relief angles. It deflects collimated light at a constant deflection angle.
A Fresnel Beamsplitter also has a linear structure with constant prism and relief angles. These two angles are equal. Collimated light splits into two equal beams and the included angle between the two beams is referred to as the separation angle.
