Whenever advanced 660nm red laser diode tech and a qualified glass coated lens are configured with a high duration metal housing tube, it is created into a professional cross line measuring tool of a 660nm red cross line laser module. It is projecting highly visible and intense red laser beam directly from an inner import 660nm red laser diode. Owing to its special use of thermal emitting system design inside a high duration metal housing tube, configured with constant electric power source supply and different dimension metal housing tube, this cross laser alignment tool is always working well as an accessory part and bringing users convenient cross line projection for multiple precise machinery processing works constantly. 
Basically 660nm red cross line laser module applies an AC/DC adapter as its electric power source. Employed by an import 660nm red laser diode within 5mW to 100mW, it is configured with 5V, 9V 1000mA AC/DC adapter, and accepting wide range electric current of 100V to 240V. In addition, owing to its special adoption of an inner metal heat sink cooling system inside its high duration anodized aluminum alloy housing tube, red laser always enables quite easy carrying and installation. In various industrial machinery processing works, red cross laser alignment tool gets strong environmental stabilization, which bears wide range operating temperature, different humidity and mechanical moving or calibration etc. It maintains long time lasting red vertical and horizontal lines generation within 10 hours per day, and up to 85% laser beam stability for all long term cross line alignment works. 
660nm wavelength belongs to the red laser light band, the generated red laser light source from a 660nm red cross line laser module also has strong penetration in industrial environments, such as metal and wood surfaces. The human eye is highly sensitive to the red laser light and can be clearly identified even in brightly light workshops. Being made with an import 660nm red laser diode within 5mW to 100mW, besides its formal cross line projection for close distance and inner room, this cross laser alignment tool is also making satisfied cross line generation within long extending distance of 25 meters and other ambient lighting occasions etc. 
Being made with a qualified glass coated lens within 10, 15 and 110 degree fan angles and adjustable focus optic lens inside a durable metal housing tube, this 660nm red cross line laser module also gets low laser beam divergence fan angle and clear cross line edges, which can achieve submillimeter or even higher precision positioning to meet the needs of precision processing. It is a necessity for laser operators to make correct selection of output power and optic lens fan angle. This ultra compact size red cross laser alignment can be flexibly integrated into various processing equipment without complex debugging, ready to use. Usually is widely used for a lot of industrial mechanical processing works, including metal cutting, welding, and woodworking, the red cross line source can quickly mark the processing starting point, boundary, or center line, helping operators to accurately align work pieces and equipment (such as cutting machines and welding guns).
