The Powell lens laser line generator acquires the best line alignment result while comparing with glass cylindrical lens or plastic coated lens. It is generating highly uniform distribution laser beam from beam aperture, getting even brighter laser light emission than formal Gaussian distribution laser beam. It generates a two-dimensional aspheric curve, which is transferring intense laser beam into uniformly illuminated straight line from beam aperture. Especially in occasion of line alignment at quite long distance, non Gaussian distribution laser beam is converted into extremely fine and straight line, keeping the same brightness from middle part towards both ends, thus guaranteeing the highest level of accuracy line alignment in distance.

At present time, this Powell lens laser line generator gets selected fan angle of 16°, 20°, 30°, 45°, 50°, 60°, 93°, which is generating highly straight laser line with different line length and line thickness in use. Under formal laser line alignment work, line laser module produces super fine line thickness of 0.3mm, 1mm, 2mm, 2.5mm, 3mm, 5mm as expected. It is basic information laser line users should learn, including required line length, line thickness and work distance from beam aperture to targeting surface. Laser tech engineers make a series of calculation and experiment, line laser would be selected with correct output power and Powell lens degree so as to achieve no mistake line alignment.

The Powell lens laser line generator gets the most useful design of adjustable focus. After quite easy screw of adjustable cylindrical lens, it gets the most rapid laser light concentration, converting into the finest laser line in use. It is getting freely selected wavelength of 405nm, 445nm, 515nm, 532nm, 635nm, 650nm, 808nm, and 980nm. Unless the genuine laser line alignment is processed without sunlight, high uniformity line laser modules would make quite easy and convenient alignment result for various application fields, including laser scanning, machine vision system, construction and process control etc.
