Wedge Prisms are optical elements designed with plane-inclined surfaces, typically inclined at very small angles towards each other. These prisms are ideal for beam steering applications, where they can be used to divert light towards their thicker portion. By selecting the appropriate wedge, precise beam deviation can be achieved without affecting other beam parameters.

When two wedges with sloping surfaces in close proximity are used together and counter-rotated, continuous variation of beam deviation can be produced. The prisms are available in standard and precision types, and with different wedge angles to suit specific requirements.
