How do I prevent laser beams from damaging broadcast camera sensors?

Practical Protection Steps

• Map camera positions and lens angles first, then design beam paths that stay clear of them
• Run a full camera test with the real lenses before the first recording
• Reduce power or increase scan speed where beams must pass near a lens
• Zone the beam path so high-intensity effects stay in areas no camera can see
• Enable scan-fail protection so output stops when a galvanometer stops moving

Why Scan-Fail Protection Matters

• A stopped scanner turns a moving beam into a single static point with far higher energy
• Scan-fail logic detects the stall and cuts or diverts output within milliseconds
• Interlocks also protect presenters, performers and crew who move between cameras
