Powerful Blue Dot Laser Set [15W] [450nm]

Description: 
A blue laser is a laser that emits electromagnetic radiation with a wavelength between 360 and 480 nanometres, which the human eye sees as blue or violet. It made of high-quality hard aluminum that is durable and rustproof.
Blue beams are produced by helium-cadmium gas lasers at 441.6 nm, and argon-ion lasers at 458 and 488 nm.
It featured PWM drive mode which is suitable for the CNC laser engraving machine.
It should be mentioned that this is not an active laser.
It can be widely applied to such material as wood, some plastics, paper, bamboo, horns, leather, rubber stamps.

Attention:
