The use of blue line laser alignment has just saved a lot of time and reduces manual labor focus input a lot. Anytime, without spending a lot of time on prior line positioning work, there is just no need to spend extra time with the assistance of laser line generator. This 445nm blue laser module is always getting quite high output power up 50mW, thus it is just equipped with even higher operating voltage of 4.2V DC input power supply. Blue laser line is generating from the tube immediately after it is getting continuous electric power source.
At the same time, under condition that blue line laser alignment is getting quite larger size laser tube with diameter of 26mm, there is just quite larger space reserving as its cooling system. With the perfect configuration with APC driving circuit board, when this blue laser module gets constant electric current and output power supply, it is just able to keep constant blue laser line targeting in long term line aligning work. In formal line aligning work, in order to keep its reliable performance, this laser line generator is just allowing daily maximum operating time of more than 8 hours to 10 hours. Only if laser tube gets several time for cooling down, it is just able to get the most reliable line alignment work.
In order to get high security line targeting all the time, the use of blue line laser alignment should be equipped with a pair of laser safety goggles since any high power blue laser module up 50mW might produce thermal energy harmful to human eyes. In addition, it is not allowed to make direct exposure to any powerful blue laser light during the whole process of laser line targeting work. After quite simple installation and adjustment of alignment laser line thickness and laser line targeting direction, this blue laser module is just assuring no mistake line targeting effectively.
