BK7 Glass Powell Lens
PARAMETER:
The Powell lens is a quantum leap forward in line generator performance over the simple cylinder lens. A cylinder lens produces a poorly illuminated line, one limited by the non-uniform, Gaussian laser beam. The Powell lens' rounded roof is in fact a complex two-dimensional aspheric curve that generates a tremendous amount of spherical aberration that redistributes the light along the line; decreasing the light in the central area while increasing the light level at the line's ends. The result is a very uniformly illuminated line used in all manner of machine vision applications; from bio-medical and automobile assembly to chocolate chip cookie production.
The Customized Powell Prism resembles a round prism with a curved roof line. The lens is a laser line generator, stretching a narrow laser beam into a uniformly illuminated straight line

Bevel
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 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.
Supplier: Spherical lens, aspheric lens, cylindrical lens, prisms, filter, coating ,mirror, powell lens, collimator lens
Sunday Optics provides many kinds of roof prisms including Schmidt Roof Prism Lehmann Roof Prism Abbe Roof Prism Penta Roof Prism and Combined Roof Prism, etc. Lehamann Prism Material: Optical glass, H-K9L, Quartz Size:5-300mm Angle Tolerance:3 Size Tolerance:+/-0.05mm Coating: AR BBAR Metal
Penta Angle Prism are widely used in laser level, Image system, precision system, and optical area. For penta prism, the deviation angle of 90 is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled, we can produce high precision penta angle prism,and make coating according to customer's request.
