High Precision Powell Lens

Product Family Description
Ideal for Alignment and Machine Vision Applications
Multiple Fan Angles Available
Creates Uniform, Straight Line

Powell Lenses, also known as Laser Line Generator, create straight, uniform laser lines by fanning out collimated beams in one dimension. This can be contrasted with standard cylindrical lenses, which produce diverging laser lines with Gaussian intensity profiles. Fan angles of 10°-90° are available.

The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields, convert laser beams into uniform, straight lines. Unlike cylindrical lenses, which generate Gaussian beam profiles with hot-spot center points and fading edges, Powell Lenses provide an even distribution of energy along the length of the entire line.

We provide Powell lens in two precision, one is High Precision Powell Lens; the other is Standard Technology Powell Lens, Please see below to distinguish the two precision powell lens.
