Introduction:

 

    Laser mirrors are an important component of laser light transmission systems. In Co2 laser light path, the mirror can have two applications, the laser tube mirror can be used as the rear end mirror, the lens with a certain curvature of the base, play the role of shock laser; laser design in some, laser reflection Mirror in the laser tube to change the light, play a role in reducing the length of the laser tube; outside the laser tube, mirror and focusing mirror with a complete optical path, making the laser machine design more space-saving and minimize laser loss , To keep the maximum laser work power.

 

Features:

 

• In the CO2 laser industry, the transmission band of the working wavelength reaches 96.8%

• High reflection efficiency, small heat distortion, scratch resistance, long service life, low power lost.​

• The mirror uses molybdenum as a substrate, molybdenum reflector can work in harsh conditions, and long life, high power, the surface without coating, wiping resistance.
