1 Scope
This document specifies the technical requirements and labeling for laser eye-protectors, and describes corresponding test methods.
It applies to eye-protectors (including filters, frames, side shields, etc.) designed to prevent accidental exposure to laser radiation (wavelength range: 180 nm–1 mm), such as laser goggles, laser eye shields, or laser face masks/visors; also applicable to eye-protectors used for laser alignment.
This document does not apply to laser-protective filters used as observation windows on laser equipment, nor to filters on optical devices (e.g., microscopes or magnifiers).
2 Normative References
The following documents contain provisions that, through reference in this text, constitute essential requirements. For dated references, only the cited version applies; for undated references, the latest version (including amendments) applies.
GB/T 2410: Determination of light transmittance and haze for transparent plastics
GB 3609.1: Eye and face protection—Welding protection—Part 1: Welding eye-protectors
GB/T 32166.2-2015: Personal protective equipment—Eye and face protection—Occupational eye and face protectors—Part 2: Measurement methods
3 Terms and Definitions
Terms defined in GB/T 30042-2013 and the following apply:
3.1 Resistance Category (RC): The maximum irradiance or exposure level a laser protector can withstand without degradation.
3.2 Optical Density (OD): Logarithm (base 10) of the reciprocal of spectral transmittance (see Formula 1).
3.3 Pulse Duration: Time difference between half-power points of pulse rise/fall (for ultrashort pulses, related to spectral bandwidth).
4 Technical Requirements
4.1 Optical Density (OD)
For multi-wavelength protectors, OD values must be specified for each wavelength/range.
If OD is wavelength-dependent, the minimum value within the range shall be provided.
OD values >2.9 shall be rounded down (max 8); ≤2.9 may be rounded or kept to one decimal place.
4.2 Visible Light Transmittance
Must generally be ≥20%. If <20%, a warning shall be included: Low visible transmittance may impair hazard recognition.
4.3 Resistance Category (RC)
All protected wavelengths/ranges must be specified.
Filters, side shields, and frames must withstand 5 s or 50 pulses (whichever is longer) of laser exposure without damage (e.g., cracking, melting, or coating detachment).
4.4 Laser Exposure Duration
Duration shall be categorized as continuous (C), pulsed (P), short-pulsed (S), or ultrashort-pulsed (U) (see Table 1).
4.5 Short-Pulse Transmittance
For S/U lasers, spectral transmittance under saturated absorption must be tested.
4.6 Lens Uniformity (Plano Lenses)
Spherical/cylindrical power and prism diopter differences shall comply with Table 2.
4.7 Corrective Lenses
Power tolerances for corrective lenses shall meet Table 3.
4.8 Filter Material & Surface Quality
No defects (bubbles, scratches, or impurities) affecting performance.
Scatter limits: ≤3% haze (for ≥20% transmittance) or ≤3.0 cd·m⁻²·lx⁻¹ (for <20%).
4.9 Environmental Stability
UV Resistance: ≤10% transmittance change after testing.
Heat Resistance: OD shall not decrease; transmittance change ≤10%.
Flame Resistance: No sustained burning.
4.10 Field of View
Horizontal: ≥40° temporal, ≥20° nasal per eye.
Vertical: ≥30° above/below the line of sight.
