If users are getting serious need of highly clear and accurate dot measurement, it is not able to rely on manual dot projecting tool, but making even better job with a pro red dot laser alignment within 5mW to 100mW. It projects pure and bright red laser light source, after getting less than 1mrad laser beam divergence and special TEM00 laser beam mode, it assures the most precise and the brightest red dot projection at various work distances.
Only after advanced use of durable anodized aluminum alloy housing tube, and special use of electric wires, this 635nm red laser diode module enables freely installed distance of 3 meters, easy and quick reaching of red dot projection in continuous use. After easy mounting and adjusting to correct position, it just assures high level of accuracy and high brightness red dot alignment for military targeting, laser communication, drilling system high tech and lab experiment etc.
