what wavelength range is considered a retinal hazard
One of the. main considerations in the retinal hazard (wavelength range of 400 nm to 1400 nm at IEC 60825-1. or 380 nm to 1400 nm at IEC 62471) is the size of the focal spot on the retina - the smaller this. becomes, the higher the power/energy density and consequently - the higher the hazard.
