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
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.
Hanzhong Brisun Optics Co., Ltd. Is the high High precision optical element manufacturer provides customized production of Various optical lenses, including spherical lens, cylindrical lens, optical window, mirror, prism, filter, metal base mirror and other high-precision optical elements. The base materials include various optical glass, fused quartz, calcium fluoride (CaF2), zinc selenide (ZnSe), germanium (GE), silicon (SI), sapphire, metal and other materials. And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings.
The plane convex cylindrical lens will focus the incident light on the line with positive focal length. It is composed of a plane and a convex cylinder. It is often used to focus parallel or divergent beams on the line or change the aspect ratio of the image. The flat concave cylindrical lens is composed of a plane and a concave cylinder, and its focal length is negative. It is often used to focus parallel or divergent beams on the line or change the aspect ratio of the image. Borisun optics provides cylindrical lenses without coating and coated with antireflection film. Antireflective film options include UV, VIS, NIR, and SWIR. Germanium, silicon or zinc selenide substrates are suitable for infrared applications, while fused quartz is suitable for ultraviolet applications.

Plano Convex or Concave Square Cylindrical Cylinder Lens
Cylinder Lenses are offered in both plano-concave and plano-convex configurations, they are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylinder Lenses are available with positive or negative focal lengths, they are used for the optics, lasers, medical science, electronics, tele-communication and others.
1. Cylindrical lens with its circumference surface polished.
2. Applicable for laser focusing into a line, changing beam shape into sheet-shape, or irradiating at a distance with elongated line
3. Focal length shortened by reducing the rod lense diameter compared to cylindrical lenses
4. Distortion-free, flexion-free, straight line gainable when projection was made at a distance, by precised process and polishing.
5. Suitable for collecting large sum of light into sensor by putting it right in front of line sensor
Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications

Optical Cylindrical lens
PARAMETER:
A plano concave cylindrical lens is used to expand light in on axis. A negative cylindrical lens is able to diverge collimated input light away from a line. Plano-concave cylindrical lenses are used for one-dimensional compression of images, anamorphic beam shaping, and laser line generation.
