Description

Details

The Powell lens has an advantage over cylindrical lenses because latter one produces a poorly illuminated  line, limited by the non-uniform Gaussian laser beam. Huge spherical aberration redistribute light along the line, decreasing the light in the central area while increasing the light intensity at the line's end. The outcome of a Powell lens is uniformly illuminated line used in all forms of machine vision applications.

Features
  • Generates uniform laser line
  • Fan angle from 1° up to 90°
  • Line uniformity better than 25 % total variation in line intensity
  • Line straighness better than 0.1 %
  • Custom made lenses also available
