In any type of highly precise and fine enough line alignment at various work distances, it is the best job to operate a Berlinlasers 532nm green laser line generator within 5mW to 100mW. It projects the most visible and the brightest green laser light, after getting low laser beam divergence of less than 1mrad and special use of a separate crystal lens, it keeps work with high fineness green line projection in continuous use. Available with wide fan angles of 10 to 93 degree, only after its correct use of output power and optic lens degree, this green line laser module projects highly straight green line within 0.5 meter to 6 meters, and high level of accuracy line generation for various application fields, including stone, wood, metal and garment processing, sand milling, lumber machine, textile garment processing and high tech work etc.
