Laser Protective Eyewear

Optosigma Laser Protective Eyewear – made by YAMAMOTO Japan – provides personal eye protection for laser lab workers, complying with CE EN 207 (European) and ANSI Z136.1 (US) laser safety standards. Selection depends on laser wavelength and maximum output power.

Optical density and wavelength ranges:
– UV goggles (190-380 nm), for excimer, frequency-tripled Nd:YAG (355 nm), HeCd (325 nm)
– Visible goggles by wavelength: Green 532 nm, for Nd:YAG second harmonic, Red 633-660 nm, for He-Ne and red diode lasers, NIR 780-1064 nm, for Nd:YAG, diode, Ti:Sapphire
– Broadband goggles: single pair covers multiple wavelength ranges (e.g. 532+1064 nm)
– CO2 10.6 um: polycarbonate lens; OD 4+ at 10.6 um

Frame styles:
– Goggle (wraparound): full side protection; recommended for high-power class 4 laser work
– Safety glasses (fit over): wear over prescription glasses; lower side protection
– Lightweight frames for extended wear in spectroscopy and microscopy labs

Compliance markings:
– CE EN 207 marking with scale number (L or D rated)
– Optical density and wavelength range printed on lens
– Visible light transmission: typically 20-60% for operator visibility
