Any time users are not able to make quick response and good direction dot alignment at long work distance, it is just a very nice chance for users to apply a 445nm blue laser diode module. It keeps work with intense and formal brightness blue laser light directly from a 445nm blue laser diode up to 50mW to 100mW. It is an industrial stabilized dot measuring tool. Being made with a metal heat sink cooling system, and APC, ACC driving circuit board, it assures good thermal emitting and highly stable blue dot alignment within long lasting time of 8 to 10 hours.
The genuine dot alignment with 445nm blue laser diode module is continuing for quite long time. The advanced use of glass coated lens has just substituted formal plastic coated lens. After up to 24 hours aging preventing and beam stability tests, and proper use by skilled users or professionals, it is able to maintain highly stable and no decay light dot generation in long lasting use. Only if blue dot laser gets correct use of output power and freely adjusted dot diameter and dot emitting direction, this blue laser makes sure of high precise, good direction and low cost dot alignment at great distance constantly.
