Whenever dot alignment is processing at quite long work distance, not simply relying on a simple laser pointer, it is brave choice to use 50mW 445nm blue laser diode module. It is design with high duration aircraft used aluminum alloy housing tube and inner metal heat sink cooling system. Within wide range operating temperature, it is achieving superior nice thermal emitting and highly stable blue dot alignment in continuous use.
AC/DC adapter is providing continuous electric power source from 50mW 445nm blue laser diode module, which is assuring highly stable blue dot projection under increasing temperature. The inner APC, ACC driving circuit board is protecting itself from burning out or damage. In practical blue laser dot projection, after quite easy installation and adjustment of laser beam focus, it makes no mistake and no barrier dot indication onto multiple surfaces effectively.
