PROTECTION OF THE HUMAN EYE FROM LASER RADIATION,
Abstract
Various possibilities for protecting the human eye from blinding through laser radiation have been considered. Of the investigated selectively absorptive and/or selectively reflective (dielectric) optical filters, some have to be disregarded for a variety of reasons. The Schott BG18 type filter glass, in a thickness of approximately 4.3 mm, appears to provide adequate protection in the low and medium energy pulse range and in a spectral range between 0.69 and 1.2 microns, covering the ruby as well as the Nd-doped glass and Ca WO4 lasers. The calculations are based on the assumption of equality of the burn sensitivities of the human and of the rabbit retina. (Author)
