The special use of import 635nm red laser diode and qualified glass coated lens inside its durable aircraft used aluminum alloy housing tube, it is being made into an industrial stabilized device of 635nm red dot laser diode module. It is projecting high purity and high brightness red laser light directly from its inner red laser diode. When it makes good use of cooling system and an external electric power source, it is just assuring good thermal emitting, and highly stable and clear red dot alignment at various work distances effectively.
