For the most important of all, the operation of this advanced 650nm 50mW red laser diode module always has no exact limitation of working distance. According to the instruction of noncontact red laser dot, it is always able to generate highly bright and visible red reference dot on all desired working surfaces. The noncontact red laser dot can be highly visible at quite long distance. However, the exit of laser beam divergence has just made the generating red dot becomes larger with the dot projecting distance extends.
The external laser tube of 650nm 50mW red laser diode module uses metal housing in order to get super efficient thermal conductivity. The utilization of aluminum alloy housing material always make this red laser module workable for wide operation temperature. Even in quite harsh working fields, this high powered red laser module is always able to be workable for wide working occasions from -10 degree to 50 degree Celsius.
According to easy adjustment and installation of 650nm red laser diode module on desired machine or devices, it has just no limitation of exact dot targeting direction, area or others. Even though sometimes the dot targeting surface is quite to reach, however, this portable size 50mW red laser module is just able to generate a highly visible and bright red reference dot on all working surfaces.
