Abstract:

Various possibilities for protecting the human eye from blinding through laser radiation have been considered. Of the investigated selectively absorptive andor 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
