The Powell prism is an optical line generator prism primarily used to optimize a laser beam into a straight line with uniform light density, good stability, and excellent linearity. Through a complex two-dimensional aspheric surface design, it redistributes the light path by reducing the light in the central region and increasing it at the edges, thereby forming a straight line with evenly distributed energy.
Features of Powell Prism
The Powell prism can optimally transform a laser beam into a straight line with uniform light density, good stability, and excellent linearity. Unlike cylindrical lenses, which produce a Gaussian beam with a central hotspot and fading edges, the Powell prism eliminates the central hotspot and fading edge distribution of the Gaussian beam, resulting in a straight line with evenly distributed energy. The full fan angle ranges from 1° to 120°, with standard specifications including 5°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, 80°, 90°, 110°, and 120°.
Applications of Powell Prism
Used for positioning, laser line generators, machining alignment, marking building targets, laser scanning systems, and measurement equipment. Applicable in various machine vision applications, ranging from biomedical to automotive assembly to chocolate chip cookie production; online inspection of mobile phones, military applications in aircraft, and shipyards.
