IEC 60825 Laser Classification: What Product Teams Must Document

If your product emits laser radiation — including many LiDAR, optical links, and alignment aids — IEC 60825 (and regional adoptions) drives classification, labeling, and user information.

Classification is about accessible emission

Class depends on accessible emission under defined conditions — not the bare diode datasheet wattage. Interlocks, windows, and firmware that enable higher power in service modes all matter.

Documentation pack

• Optical block diagram and wavelengths / pulse characteristics
• Measurement or calculation report supporting the claimed class
• Labels and aperture warnings matching the class
• User information: hazard explanations and maintenance restrictions
• Service mode controls if higher emissions are accessible to technicians

Pitfalls

• Claiming Class 1 while a removable cover exposes a higher class beam.
• Ignoring LED/incoherent optical rules when the product is not truly laser — wrong standard family.
• Forgetting that some jurisdictions layer additional laser product regulations on top of IEC 60825.

FAQ

Does FDA CDRH still matter for US lasers?

US laser products have historically had CDRH reporting/accession expectations alongside IEC-aligned design. Confirm current FDA expectations for your product type.
