High Precision Optical Glass Laser Line Generator Lens

Industrial Laser Line Generator Lenses

These 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 25% 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.

While it’s assumed that using cylindrical lenses creates the same effect, thus making Powell lenses unnecessary, a big difference between the line created by a cylindrical lens and that created by a Powell lens can be found in the beam intensity along the generated line. It is possible to create a laser line using cylindrical lenses, however, the intensity profile of such a line will have a Gaussian-like distribution, meaning that the line will have a higher distribution at its center and it will slowly fade away as we reach the edges.

About powell lens The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields. Worldhawk are professional supplier for powell lens, in fact, we have already become the one of the main important suppliers of powell lenses in China. cooperation with us , you will get high quality products with reasonable price and products performance at the same time .

Product application introduction:

◇Powell Lenses, also called Laser Line Generator Lens, provide an even distribution of energy along the length of the entire line; In general, we provide 9mm and 6mm powell lens, Fan angle from 10 degrees to 90 degrees, beam diameter from 0.8-5mm, H-K9L powell lens and N-SF6 powell lens; Our powell lens divide into two accuracy, High precision powell lens and Standard Technology powell lens, Laser line uniformity and distribution of energy of High precision powell lens is much even than Standard Technology powell lens.

◇Optical Mirrors in a multitude of reflective coating options, including Protected Aluminum mirror, Enhanced Aluminum mirror, Protected Silver mirror, Protected Gold mirror, or Dielectric mirror.

◇Optical Lenses are optical components designed to focus or diverge light. A Plano Convex Lens or Double Convex lens causes light to focus to a point, while a Plano Concave Lens or Double Concave Lens causes the light traveling through the lens to diverge. Achromatic Lens are ideal for applications requiring color correction, while Aspheric Lens are designed to correct spherical aberration. Germanium Lens, Silicon Lens, or ZnSe lens are ideal for transmitting the Infrared (IR) spectrum, while Fused Silica Lens is well suited for the Ultraviolet (UV).
