Wedge Prisms

Applicable for Beam Steering
Different coating options possible

Wedge prisms find applications in steering light beams. Two wedge prisms of equal power, used together can steer input light beams within a narrow cone. Wedge prism produces a small deviation to the light beam which doesn't allow the light return to the source. Holmarc offers wedge prisms in three options; uncoated, single layer MgF2 coated, and broadband AR coated.

Wedge prisms can be used as isolating components. Wedge prism may also be used to produce a small deviation which doesn’t allow light returning to source. Two wedge prisms can be combined to steer a beam anywhere within a circle defined by 4 times the angular deviation of a single wedge.



    Material :     BK7 or equivalent & UV fused sIlica
    Effective aperture :     85 %
    Surface Quality :     40 - 20 ( scratch-dig )
    Dimensional Tolerance :     + 0.0, -0.2 mm
    Angle tolerance :     +/- 3 arc min
    Surface flatness :     λ / 4 @ 632.8 nm
    Thin edge thickness :     3 mm
    Bevel :     0.2 mm x 45°
    AR coating :     Optional



By combining two wedge prisms each of which can be rotated independently, it is possible to direct the beam anywhere within the cone angle defined by 4x the specified angular deviation of one wedge.
