Necessity of Laser Safety Curtains 

     Laser safety curtains are essential protective barriers designed to contain hazardous laser radiation, preventing accidental exposure to operators and                                               bystanders. Their key benefits include: 

     1. Personnel Protection – Blocking harmful laser beams (Class 3B/4) to avoid eye/skin injuries.  

     2. Regulatory Compliance – Meeting workplace safety standards (e.g., GB 7247.1/4/13、IEC60825-1/13、CE/EN 60825-1/4, OSHA ).  

     3. Beam Containment – Preventing stray reflections or scattered laser light from escaping the work area.  

     4. Workspace Safety – Enabling safe operation in shared or open environments.  

     Key Application Scenarios 

     1. Industrial Laser Processing 

          - Laser cutting, welding, and engraving in manufacturing.  

          - Protection against high-power CO₂ or fiber lasers.  

     2. Medical & Aesthetic Lasers  

          - Shielding operators during laser surgeries or dermatological treatments.  

     3. Research & Laboratories

          - Containing beams in physics labs, R&D facilities, or university settings.  

     4. Military & Defense  

          - Securing testing areas for laser-based weaponry or targeting systems.  

     5. Entertainment & Displays  

          - Safeguarding audiences from high-power lasers in light shows.  

     Material & Selection Criteria  

         - Optical Density (OD): Must match the laser wavelength (e.g., OD4+ for 1064nm Nd:YAG lasers).  

         - Flame Resistance: Critical for high-power industrial lasers.  

         - Flexibility & Portability: For temporary setups or mobile laser systems.  

     By integrating laser safety curtains, industries mitigate risks while maintaining operational efficiency. Proper selection based on laser type and power 

     ensures optimal protection.
