Roof Powell Lens
Optical Powell Lens
Laser Line Generator Lenses, also known as Powell lenses, generate a straight, uniform laser line by fanning out a collimated beam in one dimension, as shown in the diagram above. The apex of each lens features an aspheric curve that evenly distributes the optical power, resulting in an intensity variation of less than 20% over the center portion of the line. You will get more even energy distribution along the laser line than using the rod lenses and lenses.
Powell lens are available with output fan angles of 5°- -110°. They are designed for use at 405-900 nm with 2 an input beam diameter of 0.8 -5.0mm (1/e ). Rectangular input beam can be customized for powell lens.
The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields.
