|When users are looking for a good direction dot alignment， either it is pointing at close or long distance， it is making good job with pure light 635nm red laser diode module within 5mW to 100mW. It projects the most intense red laser beam at several miles far away. Owing to special use of cooling system inside different dimension housing tube， it just achieves good thermal emitting and increasing stability red dot projection in continuous use.
This red dot laser applies different dimension metal housing tube. It should be working with clear red dot projection and no light fade in use. It applies a qualified glass coated lens and glass window inside 16mm and 26mm diameter tube. Within freely installed distance of 3 meters， after correct use of output power， it achieves high precision and long lasting dot alignment for both industrial and science precise dot measuring fields effectively.
