National technical systems (NTS), under sponsorship of department of energy, has been successful in achieving super high efficiency holographic reflection mirrors. Because the technology allows for adjustable reflection band pass wavelengths, both narrow band (delta lambda < than 20nm) and broadband (delta lambda approx. 300Nm) holographic mirrors have been fabricated this past year with maximum optical densities of 6. Recently, nts has extended this technology from the visible spectrum into the near ir region of the spectrum (450 < lambda < 1600nm). A new method of processing which allows for fabrication of holographic mirror which reflects both the laser fundamental and its first overtone (e.g., ndyg 1.06 and 0.53 micros) has recently been documented in the nts laboratories. It is proposed to apply this super high efficiency holographic technology to the protection of the eye against visible and near IR wavelengths. By fabricating visors using this technology protection against picosecond as well as multisecond time frames can be achieved, while still maintaining high scotopic and photoic see-through efficiencies.
