What is the best method for make clear and accurate enough cross line generation? Under consideration of high work efficiency and low production cost, it is a correct choice for users to apply a 660nm red cross laser alignment. It emits moderate brightness red laser light directly from 660nm red laser diode. Owing to its advanced use of qualified glass coated lens with different fan angles and constant power source supply, this red laser module enables convenient installation, and easy red cross line source generation onto multiple working surfaces.
