In any type of high precision and high stability line alignment at various work distances, it would be full of challenge for users to get ideal line aligning accuracy before selecting a quite practically used device, such as a Berlinlasers 532nm green line laser module. It is an industrial stabilized line alignment tool. Being made with 5V, 9V 1000mA DC power supply, within wide range output power of 5mW to 100mW, it projects highly visible green laser beam at several miles, but also makes good job for highly clear green line projection for multiple raw material processing works.
The unique use of a qualified glass coated lens is assuring high linear quality and straight green line projection form a 532nm green line laser module. Available with wide range fan angles of 10 to 110 degree, it is projecting 0.5 meter to 6 meters line lengths. Within freely installed distance of 3 meters, it assures no mistake line alignment for both industrial nd high tech precise line measuring works perfectly.
