Place of Origin: Jilin, China Brand Name: YT Model Number: YTV122 Material: Optical Glass Surface Quality: 40/20, 40-20 Dimension Tolerance: 0.0/-0.1mm Angle Tolerance: 3 Arcmin Flatness: 1/4 Lambda, L/4 Substrate: Fused silica/BK7/K9 Wedge Angle: 0° 58' Thickness (mm): 1.5 Wavelength Range (nm):: 350 - 2200 Diameter (mm): 12.5 Angle Tolerance (arcsec): ±30 Ray Deviation (°): 0.5 Coating: customized 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. Two wedge prisms can be used as an anamorphic pair for beam shaping (to correct the elliptical shape of diode outputs). Or, a pair of wedge prisms can steer a beam anywhere within a circle described by the full angle 4θ, where θ is the deviation from a single prism. This beam steering is accomplished by rotating the two wedge prisms independently of each other, and is typically used to scan a beam to different locations in imaging applications.
