In order to make highly clear dot alignment at various work distances, in those of industrial and high tech precise dot measuring work fields, it is making good job with a Berlinlasers 635nm red laser diode module within 5mW to 100mW. It projects at least 3 times brighter red laser light than formal 650nm red laser.
Available with low laser beam divergence of less than 1mrad and special TEM00 laser beam mode, this 635nm red dot laser is projecting the most compact size and the brightest red dot emission in continuous use. It is applying qualified glass coated lens, after beam stability test and aging preventing test, it is keeping work with stable and reliable red dot emission in all occasions. Only after correct use of output power, this dot laser alignment makes good job for industrial precise dot measurement, lab experiment, high tech, red laser sight, drilling system etc.
