Whenever users are looking for an easy operating and highly clear dot alignment, either it is pointing at close or long distance, it makes good job with a Berlinlasers 650nm red laser diode module within 5mW to 100mW. The advanced use of an import 650nm red laser diode and metal heat sink cooling system are cooperating well, which just assures the most reliable red dot projection within 8 to 10 hours use.
This red dot laser alignment applies strict laser beam stability test and special use of a glass coated lens inside highly durable metal housing tube. It keeps work with high intensity and high transmittance red laser light emission, and highly clear red dot projection under moisture or dust etc. Within freely installed distance of 3meters, without the use of sunlight, it provides users the most precise and the most reliable red dot aligning source for drilling system, military targeting, laser marking, laser engraving and high tech work etc.
