What is Fiber Laser Protection Mirrior/Lens?
The Fiber Laser Cutting Machine Protective Lens serves as a protective barrier between the laser beam and the cutting machine, preventing damage caused by reflected laser energy.
This fiber laser protective lens effectively redirects the laser beam towards the workpiece, ensuring precise and efficient cutting operations while extending the lifespan of the machine.

The lifespan of laser cutting and laser welding machine lenses can vary depending on several factors. These factors include the laser power, operating conditions, maintenance practices, and the quality of the lenses themselves.
Typically, high-quality lenses used in laser cutting and welding machines have a relatively long lifespan. With proper care and maintenance, they can last for hundreds or even thousands of hours of operation. However, it's important to note that the lenses will gradually degrade over time due to factors such as thermal stress, beam intensity, and debris accumulation.
Regular cleaning and inspection of the lenses are essential to prolong their lifespan. Keeping the lenses free from dirt, debris, and residue will help maintain their optical clarity and efficiency. Additionally, following the manufacturer's recommended maintenance procedures and replacing the lenses when necessary will ensure optimal performance and extend their lifespan.

The focusing lens plays a crucial role in converging the laser beam to a specific focal point. It enables precise and controlled laser cutting, engraving, or marking applications by concentrating the laser energy at the desired spot.




It is forbidden to touch both side of the lens directly with your hands when replace the protective lens/safety windows.
Pls wear gloves,hold the slide parts of the lens.
