Whenever 660nm red laser diode and qualified glass coated lens are integrated into a durable anodized aluminum alloy housing tube, it is designed and manufactured into a professional dot measuring tool of a Berlinlasers 660nm red laser diode module. It emits intense and bright red laser light at several miles far away. Cooperated with adjustable focus optic lens design in front of laser beam aperture, red laser enables immediate red laser light concentration and converts into a compact size, good round shape and highly bright red dot projection in distance.

Within the lowest energy and time consumption, laser diode module enables long term lasted red laser light and red dot projection, allowing easy installation and debugging with small desktop marking machines. A correct output power made laser device can provide ideal dot alignment source for non metallic material marking, simple metal marking, auxiliary positioning marking etc.
