Laser Protective Lens

 

The role of a fiber laser protective lens is to safeguard the critical optical components in fiber laser systems. It prevents contaminants like metal debris, dust, and smoke from reaching the internal optics, which helps avoid damage and degradation to the laser system's focusing lens. By acting as a barrier, the protective lens enhances the longevity and reliability of the fiber laser, ensuring consistent performance and maintaining high cutting or welding precision. 

High transmittance and reflectivity:

Fiber laser lenses are made of high purity glass or crystal materials, with extremely high transmittance and reflectivity, which can effectively control the energy distribution and direction of the laser beam. The specific values of transmittance and reflectivity depend on the design of the lens and the choice of materials, and can usually meet the needs of fiber lasers for high-precision laser beam control.

High stability and durability:

Fiber laser lenses can work stably in harsh environments such as high temperature, high humidity and high pressure, and are not susceptible to optical distortion caused by environmental factors. Its material has good corrosion resistance and wear resistance, and can maintain the stability of optical properties for a long time.

05

 

Versatility:

 

The retaining cap essentially holds all of the consumable parts of the torch together. As temperatures at this end of the machine are extremely high, it's not just the parts creating and focussing the arc that are worn down; the component holding them together also degrades over time.

 

Premium Quality

 

Made of high quality quartz crystal.

Cleaning method:

Put finger covers on your left thumb and index finger.

Spray ethanol onto polyester cotton swabs.

Left thumb and index finger gently pinch the side edge of the lens, (Note: The finger cover should not touch the surface of the lens, so as not to leave traces)

 

Put the lens facing your eyes, hold the polyester cotton swab in your right hand, and clean both sides of the lens surface from the bottom up. After cleaning, make sure that there is no residue: Detergent, floating ash, foreign matter, impurities, etc.
