Bk7 Glass Powell Lens - China

PARAMETER:

The Powell lens is a quantum leap forward in line generator performance over the simple cylinder lens.

A cylinder lens produces a poorly illuminated line, one limited by the non-uniform, Gaussian laser beam.

The Powell lens' rounded roof is in fact a complex two-dimensional aspheric curve that generates a tremendous amount of spherical aberration that redistributes the light along the line; decreasing the light in the central area while increasing the light level at the line's ends.

The result is a very uniformly illuminated line used in all manner of machine vision applications; from bio-medical and automobile assembly to chocolate chip cookie production.

The Customized Powell Prism 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
