Powell Lens

Powell Lens (Laser Line Generator Lens)

 

Normally cylindrical lenses can produce straight line, but it only generates Gaussian beam profiles with hot-spot center points and fading edges. Unlike cylindrical lens, laser line generator lens can produce an uniform distribution of energy along the line. While, the input beam diameter must be smaller than 1mm.

 

Creates Uniform, Straight Line
Several Fan Angles Available
Ideal for Alignment and Machine Vision Application
