Powellenses is one kind of opticaruling lens, xi'an lingyue machinery&electr.Ltd.Cnsupply powellenses that divergence angle from 10íp to 100íp, the standard have 30íp\45íp\53íp\60íp\70íp\85íp\90íp.
When 1mm laser bean get through the powellenses, it is optimized transformed a line which is uniform, stability, straight .Lineation by powellenses is better than aspheric lensse, as by powellense can cancelling centrahotspot of gaussian beams and fade-marginadistribution.

Applied range:
Laser scriber
Machining -position by makeing
Building- graticule by makeing
Laser scanning system
Customs can order by index following
Divergence angle
Work distance
Beam wavelength or beam diameter
Width of lineation.

Standard:
Divergence angle materials
