Laser Safety In normal operation, LIPs are fundamentally as safe as lamp projectors Assuming radiance and beam geometry are equivalent LIPs are designed to emit light nearly identical to a lamp projector But – “raw”, collimated laser beams can be harmful Since laser sources are inside the projector, care must be taken Particular considerations during maintenance access Since laser sources are used, special safety regulations applyConsult your manufacturer for specific safetyrequirements, and to answer any questionsabout your particular situationOctober 17, 2019LIPA Webinar: Understanding LIPs Safety RegulationsSlide 13

Summary LIPs present hazard similar to lamp projectors Very unlike raw laser beams However, due to embedded laser, laser regulations apply US is now (nearly) harmonized to worldwide IEC standard Most high-power LIPs are RG3, and therefore require variance Variances are specific to a manufacturer & model family!
