Wedge Prism

Wedge PrismsFeatures: 1° to 15° Beam Deviation at 632.8nm, Ideal for beam steering.Applications: Beam steering, Projection Systems, Imaging Systems, Laser Measurement Systems, etc.Description:Wedge prism is optical element with plane-inclined surfaces; usually the faces are inclined toward one another at very small angles. It diverts light toward its thicker portion. By selecting appropriate wedge it is easy to create precise beam deviation without affecting other beam parameters. If two wedges are used together with sloping surfaces in close proximity it is possible to produce a continuous variation of beam deviation by counter - rotating the wedges.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. A single wedge prism's ability to deviate the angle of an incident beam is measured in Diopters with 1 diopter deviating the beam 1cm at a 1m working distance.Specifications: Material: BK7 or UV Fused SilicaDesign Wavelength: BK7: 632.8nm, [email protected]                                    UVFS: 355nm, n=1.476@355nmDimension Tolerance: +0.0/-0.2mmThickness: 3mm on the thinnest edgeWedge Angle Tolerance: <3 arc minutesFlatness: <λ/[email protected] Quality: 60/40 scratch and digClear Aperture: >90%Deviation Angle From 1deg to 10degCoating: Specified by customer
