Description
Powell Prisms – Uniform Line Generators for Laser Systems
Detailed Description:
Powell Prisms are aspheric prismatic lenses designed to convert a collimated laser beam into a uniform, straight line with consistent intensity distribution along its length. Unlike cylindrical lenses, they eliminate Gaussian beam profile hotspots, making them ideal for laser line scanning, machine vision, and 3D scanning applications.
Key Specifications:
Materials: BK7, Fused Silica
Line Angle: 10° ~ 120° (custom angles available)
Input Beam Diameter: 0.5mm – 10mm
Surface Quality: 40/20, 20/10
Surface Accuracy: λ/4 @ 633nm
Coating: AR coating (VIS/NIR)
Uniformity: >90% intensity uniformity along the line
Applications:
Laser line scanners, machine vision, 3D scanning, industrial inspection, barcode readers, laser alignment.
