Whatever kind of working surface users are looking for an easy operating and highly precise line measurement, no matter it is pointing at close or long distance, it is not easy job to get ideal line aligning accuracy immediately. At the same time, on basis of advanced 650nm red laser diode and separate crystal lens with different fan angles, it is being made into a quite practically used device of red line laser module. It enables easy and quick red line projection onto various working surfaces. In occasion that it gets constant power source supply and proper installation onto any other industrial device or equipment, this laser line generator just assures high level of accuracy and high efficiency line generation onto a lot of working surfaces constantly.
This 650nm red line laser module is easy to use in any type of industrial precise line measuring work fields. It applies the best quality separate crystal lens. Before it is flowing into laser market, it also passes through a series of strict laser beam stability test, aging preventing test, alternative high and low temperature changing test up to 24 hours. It projects the best quality red laser light in type of non Gaussian distribution red laser light. No matter it is pointing at close or long distance, this red laser line generator is working well with high fineness and high brightness red reference line projection. 
Whatever kind of working surface it is pointing, it is keeping work with the same line brightness from middle part towards both ends, thus 650nm red line laser module always assures the highest level of accuracy line projection in all precise device manufacturing work fields. Available with wide fan angles of 10 to 93 degree, after projection of highly straight red line within 0.5 meter to 6 meters, only after its basic measurement and experiment of technical data, a correct output power and optic lens degree made laser line generator just achieves no mistake measurement for a lot of application fields, including laser cutting, sand milling, lumber machine, textile garment processing and high tech work etc.
Within freely installed distance of 3 meters, not limited by long distance, high height and other complex working environments etc, this ultra compact size tube made non Gaussian beam 650nm red line laser module makes sure of the most convenient installation, and the most rapid red line indication onto any vertical or horizontal surface. On basis of special use of adjustable focus optic lens, this alignment laser gets high concentration red laser light emission, increasing accuracy and fineness red line projection at great distance. Only if users are taking laser safety measure and wearing correct 650nm wavelength preventing laser safety goggles, without any eye exposure to laser beam aperture, it achieves easy and secured line measurement in all occasions.
