What laser requirements apply in museums that hold relics and sensitive exhibits?
Direct answerEquipment must run with low heat output and filter harmful UV wavelengths. Never project directly onto fragile artifacts, paintings or ancient specimens, and keep beams on designated projection surfaces only.
Protection Rules for Sensitive Exhibits
- Select equipment with low thermal output and UV filtering in the optical path
- Never aim a laser directly at a relic, painting, manuscript or specimen
- Control cumulative light exposure and total daily illumination time to prevent fading
- Plan the beam path in advance and keep it on designated projection surfaces
- Include an emergency stop and interlock so output stops instantly if a fixture is bumped or moved
What to Prepare Before the Show Is Approved
- A beam path drawing approved by the exhibition curator and conservation staff
- Documented light exposure figures per exhibit surface
- A maintenance schedule that avoids handling of protected objects
- A written response procedure if a beam path change is requested
Conservation staff should sign off the beam path and exposure figures before the installation is fixed in place.
