No matter dot measuring work is processing at close or long distance, not the same as a red laser pointer, it is making even more efficient job with Berlinlasers 638nm red laser diode module. It is projecting high purity and high brightness red laser light from a 638nm red laser diode directly. The advanced use of metal heat sink and APC, ACC driving circuit board are configured with 16mm and 26mm diameter metal housing tube. It always assures superior nice thermal emitting, and highly stable and reliable red dot emission within long lasting time of 8 to 10 hours.
This 638nm red laser diode module gets the lowest laser beam divergence and special TEM00 laser beam mode, which is working well with the most compact size and the brightest red dot emission at various work distances. It enables correct use of output power and freely adjusted laser beam focus and dot emitting direction within three dimensions. Not relying on any manual labor force input, within the maximum work distance of 25 meters, this red dot laser just brings users high precision and good direction dot alignment for multiple raw material processing works effectively.
