The generated blue laser beam is direct and practical. Even though this blue cross laser alignment is not getting brighter laser beam than 473nm blue DPSS laser tech, however, it is getting mass production of 445nm blue laser diode, which is not only able to get highly stable and reliable cross line positioning in continuous work, but also available with quite low price. Even though this blue crosshair laser module gets quite higher output power of 50mW to 100mW, it is still able to be compactly designed and manufactured with 16mm diameter laser tube.
Under condition that blue cross laser alignment is getting external electric power source of DC input power supply, equipped with the most advanced APC, ACC electric driving circuit, no matter how long it is lasted for continuous cross line positioning, this blue cross line laser module gets constant electric current supply and output power supply, making sure of the most reliable cross line positioning.
In process of continuous cross line measuring work, the tube of blue cross laser alignment temperature might increase seriously. However, laser tech engineer has just made great technical innovation of thermal emitting system, according to its constant electric current supply providing, this blue laser module gets good performance and supports more than 8 hours continuous cross line aligning. There is no possibility of laser diode and driving circuit burning out, getting extremely long serving lifetime of more than 8000 hours as well.
