Among all selectable dot measuring tool, no matter it is pointing at close or long distance, it always makes good job to operate a Berlinlasers 635nm red laser diode module. It projects long distance visible red laser light from a 635nm red laser diode, which gets low laser beam divergence and special tem00 laser beam mode. It just keeps work with the most compact size and the brightest red dot projection in long lasting use.
This 635nm red dot laser alignment gets wide range output power of 5mW to 100mW. It should be working without sunlight. Being made with qualified glass coated lens and glass window inside durable metal housing tube, it generates high transmittance red laser light and highly clear red dot projection in continuous use. Either adopting 16mm or 26mm diameter tube design, within freely installed distance of 3 meters, it brings users easy reaching and high precision dot alignment for drilling system, laser marking, laser engraving, red laser sight, military targeting and high tech etc.
