1.Wedge prisms can be used individually to deviate a laser beam a set angle, or two wedge prisms can be used together for beam steering applications.
2.A single wedge prism’s ability to deviate the angle of an incident beam is measured in Diopters with diopter deviating the beam 1cm at a 1m working distance.
3.Two wedge prisms can be used as an anamorphic pair for beam shaping (to correct the elliptical shape of diode outputs).
4.The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle. When viewing a scene through such a prism, objects will appear to be offset by an amount that varies with their distance from the prism .
