Product Features

The R7 blue diode laser is an upgraded version of the original R6 series blue laser. The performance of modified laser products is in the leading position in the world. Its wavelength is 445nm, the power is 50W, the beam quality is higher, and it has the advantage of conduction cooling.

Due to its high photon energy advantage, blue diode laser has the characteristics of high absorption rate and no spatter in the processing of copper and other metal materials. It has irreplaceable advantages in the field of material processing.

R7 series blue diode lasers will continue to launch new products, please stay tuned.
