Product Description
Spot Diameter 5mm Laser Line Powell Cylindrical Lens
Used for positioning, Laser Marking Machine, processing marking, marking building objects, laser scanning system, measuring equipment.Used in various machine vision applications;From biomedicine to car assembly to chocolate chip cookie production;Mobile phone various online detection, aircraft military applications, ship factory.
Powell prism (also known as laser linear generator lens) is an optical crossing prism, which can be optimized for the input of laser beam with 0.8mm diameter. After passing the laser beam, it can be optimized into A straight line with uniform light density, good stability and good linearity.Unlike cylindrical lenses which produce central hot spots and discoloured edge gaussian beams, the central hot spots and discoloured edges of gaussian beams can be eliminated, forming a straight line with uniform energy distribution.All fan Angle from 1 ° to 120 °, standard specification has 5 °, 10 °, 20 °, 30 °, 45 °, 60 °, 90 °, 110 °, 120 °.
Gaussian laser beam by ordinary cylindrical lens, produces the uneven distribution of straight line, and Powell AT the top of the prism is complex two-dimensional aspheric surface, through laser will produce a large number of spherical aberration, light path is redistributed, reduce the light of the central region, increase the edge of the light, to form a uniform line, suitable for all kinds of biological medicine, automobile assembly, food processing and machine vision applications.

Product application introduction:
❤Laser module include Line Laser Module, Cross Line Laser Module, Dot Laser Module... Can be used in Industrial marking devices, laser medical equipment, stage lighting and laser targeting devices, Machine vision, Laser Positioning Surveying Instrument, Laser Sight and so on.
❤Cylinder Lenses are offered in both plano-concave and plano-convex configurations, they are typically used to focus incoming light to a line, or to change the aspect ratio of an image.
❤Optical Windows are flat, plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments. Optical Windows should be selected based on the material transmission or mechanical properties of the substrate. Optical Windows do not cause change in the magnification of a system.
❤Powell Lenses, also known as laser line generating lenses, create straight, uniform laser lines by fanning out collimated beams in one dimension. The apex of each lens below features an acylindric curve that evenly redistributes the optical power of a Ø0.8 mm (1/e2), 633 nm gaussian input beam into a projected line with less than 20% intensity variation over the line's central 80% . This can be contrasted with standard cylindrical lenses, which produce diverging laser lines with Gaussian intensity profiles. Fan angles of 10° to 90° are available.
❤Powell lenses are lenses that create a straight laser line by dispersing, in a controlled way, an input collimated beam. They were first proposed in 1987 by I. Powell where he describes the design of an optical element for laser beam line expansion; that element bears some resemblance to a prism with a small radius at its apex and expands the laser beam in only one direction.
