BK7 Powell lens
Description
Powell lens is used to generate straight line. With aspherical curvature on its apex, the output line from powell lenses is even distribution of energy. For comparison, Cylindrical lenses generate gaussian beam profiles with hot-spot centre points and fading edges.
The uniformity of output line is also related with incident wavelength, beam size, divergence, and working distance.

Frequently Asked Questions
A Powell lens is an optical lens used to generate a straight line with even distribution of energy.
Cylindrical lenses generate Gaussian beam profiles with hot-spot center points and fading edges, while Powell lenses generate straight lines with even energy distribution.
The uniformity of the output line is related to incident wavelength, beam size, divergence, and working distance.
Powell lenses can be used for imaging, laser optics, spectroscopy, microscopy, and OEM applications.
Yes, all lenses are available with narrow-band or broadband antireflection coatings peaked for the major wavelength of operation, at which transmittance will exceed 99%.
