Overview

EN 207:2017 (CEN) specifies requirements, test methods and marking for laser eye-protectors - filters and complete eye-protectors designed to protect against accidental exposure to laser radiation. The standard covers the spectral range 180 nm (0.18 µm) to 1 000 µm, aligns protection requirements with EN 60825-1:2007 classifications, and includes an informative Annex B giving guidance for selection and use. EN 207:2017 does not apply to protectors intended for intentional exposure (e.g., direct beam viewing); EN 208 covers laser adjustment eye-protectors. A risk assessment is recommended before selecting protection.

Key topics and technical requirements

• Spectral transmittance: Filters and frames must meet maximum spectral transmittance limits at protected wavelengths (scale numbers are specified in the standard’s test tables).
• Luminous transmittance: Filters are assessed relative to the D65 illuminant; minimum luminous transmittance is 20% unless the manufacturer documents workplace illumination adjustments.
• Resistance to laser radiation: Filters and frames are tested for resistance to specified power/energy densities (see the standard’s Table 1). Protective effect must be maintained; no induced transmission (reversible bleaching) or eye-facing splinters are allowed.
• Optical quality and refractive values: Limits on refractive error and surface defects to ensure safe vision when wearing laser safety eyewear.
• Material stability: Resistance to UV exposure, elevated temperature, and ignition from hot surfaces is specified.
• Field of vision, construction and mechanical strength: Requirements and test methods ensure practical usability and physical durability.
• Testing, marking and manufacturer information: Detailed test schedules, required marking (scale numbers, wavelength ranges, time base) and user information are specified.

Applications and who uses EN 207:2017

EN 207 is used by:

• Manufacturers of laser safety eyewear and protective filters to design and certify products.
• Testing laboratories and conformity assessment bodies performing optical and laser-resistance tests.
• Safety managers, EHS officers, and laser operators in industry, healthcare, research and education to select appropriate laser eye-protectors based on wavelength, power, and pulse characteristics.
• Purchasing and procurement teams specifying compliant laser safety eyewear.

Practical use: match the laser parameters (wavelength, power/energy, pulse duration) to the standard’s scale numbers and marked protection range, and perform a workplace risk assessment (Annex B) before selection.
