PhotonSafe Laser Safety Barriers

Movable laser protection Walls - perfect for laser welding, laser cleaning, laser cladding, ..

Constructed of the patented panel PhotonSafe Laser Shield 4005™ and aluminum frames, Our protection walls are designed for the protection of kilowatt-level laser, especially for high power laser welding and lser cleaning, laser processing workshop and laser device, with its characteristics of high level protection and flexibility. The barriers Laser Knight, when they first came out in the year of 2019,  successfully get patent for an invention in 2022. They are the first laser protective barriers with independent intellectual property rights.

As the rapid growth and wide application of high power laser, PhotonSafe has deeply researched and developed its hit product PhotonSafe Protection screens series, and now launch the renewed barriers to meet laser safety demand of high power laser areas. The upgrading barriers are tested by a third party of authority, according to standards IEC 60825, GB/T 7247 and EN60825-1. In addition, conformity with CMA and CNAS, accreditation system which have been integrated to international mutual recognition, PhotonSafe barriers are compliant with CE standards, and meet the threshold of European market. Furthermore in conformity with many national defense recognitions, PhotonSafe barriers are widely applied to laser processing, military industrial enterprises, the fields of semiconductor and medical facilities.

PROTECTION PRINCIPLE

1. When the laser energy incident on the safety panel surface is too low to cause damage, the uniformly scattered surface effectively reduces stray light.

2. When the first layer is damaged, the patented three-layer hollow structure acts as a heat sink, rapid-ly conducting energy laterally to extend the time before the safety panel is penetrated.

3. When the first layer is penetrated, the staggered protrusions in the middle layer enlarge the beam spot, reducing laser energy density and delaying penetration of the middle and third layers. Meanwhile, the patented three-layer hollow structure continues to function as a heat sink, rapidly conducting energy laterally to further extend the time before the middle and third layers are penetrated.

At the same time, the large amount of smoke generated accumulates within the middle cavity, contaminating the laser beam, weakening its energy, and further delaying penetration of the middle and third layers.

Additionally, the visible smoke facilitates safety monitoring and early warning.
