Powell Lens is an optical scribing prism, which can optimize the laser beam to form a straight line with uniform light density, good stability and good straightness after passing through. It is superior to the scribing mode of cylindrical lens, which can eliminate the central hot spot and faded edge distribution of Gaussian beam.

We have Powell Lenses in stock with various angles and beam diameters, welcome to inquiry and purchase. We also support customers to customize various sizes and specifications.Thank you. 

When Gaussian laser beam passes through ordinary cylindrical lens, it will produce unevenly distributed straight lines, while the top of Powell prism is a complex two-dimensional aspheric surface. When the laser passes through, a large amount of spherical aberration will be generated, redistributing the light path, reducing the light in the central area and increasing the light at the edge to form a uniform straight line.

It is suitable for various machine vision applications such as positioning, laser scribing machine, processing scribing positioning, marking building targets, laser scanning system, measuring equipment, food processing, etc., from biomedicine to automobile assembly to chip production; various mobile phone online detection, aircraft military applications, shipyards.

Fan Angle Range

AOS Optics provides the Fan Angle range of Powell Lenses processing is 1 degree to 120 degrees. The current processing angles are 1°,3°, 4°, 5°, 7°, 10°, 15°, 20°, 22°, 30°, 35°, 45°, 55°, 60°, 70°, 72°, 75°, 80°, 82°, 90°, 100°, 110°, 112°, 115°, 118 degrees, and 120°. AOS Optics supports customers to customize powell lens of any angles. The Fan Angle determines the length of the laser line when the distance is certain. AOS Optics uses advanced technology to produce Powell Prism to perfectly ensure the consistency of the length of the lines of large quantities of products.

Laser Beam Diameter

AOS Optics supports customers to customize powell lens of various shapes and sizes of spots. Shapes include circular, elliptical, square, and rectangular laser spots. The beam diameter ranges from 0.5mm to 18mm. It is very important that the laser spot size matches the powell lenses. A perfect match will produce uniform lines. We have more than 100 prisms with different spot shapes and sizes, and the inventory is tens of thousands of pieces.

Uniformity of Powell Lens

 The uniformity of the lines after laser shaping by prism is the key indicator to judge the quality of prism. The high-precision products we produce reach the international level, and the uniformity can reach up to 80%-90% within 90% of the center area of ​​the line. High-precision linear lasers must use high-precision Powell prisms to play a finishing touch and icing on the cake.

Straightness of Powell Lens 

We use advanced technology to ensure the straightness of prism lines, and the straightness can be guaranteed to be 99.9%, and it is guaranteed that there are no defects such as stray light, dark lines, shadow lines, etc. around the lines.
