Product Overview
We are famous for making and exporting BK7 Glass Powell Lens in Changchun, Jilin, China. 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 Powell lens 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 . Specification Material:Fused silica/ BK7glass Diameter:I 0.8mm, I 1mm, I 2mm, I 3mm, I 5mm, I 9mm, I 10mm, I 15mm or customized size Diameter Tolerance:+0.0/-0.05mm / A 0.05mm Range of Fan:3A ,5A ,10A ,15A ,20A ,30A ,45A ,53A ,60A ,70A ,75A ,85A ,90A 96A ,100A ,110A ,120A Angle tolerance:90% Bevel:
