Product Description

PRODUCT DESCRIPTION

The Powell lens resembles a round prism with a curved roof line. The lens is a laser line generator, stretching a narrow laser beam into a uniformly illuminated straight line.It 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 alignment, all forms of machine vision applications,and construction and process control.

FEATURE

1. Generates uniform laser line

2. Accurate Fan angle

3. Excellent uniformity
