Physical and Optical Evaluation of Reflection Dielectric Laser Eye Protection (LEP) Spectacles

摘要

The physical properties, optical quality, spectral transmittance and laser protection measurements of reflective dielectric laser eye protection (LEP) spectacles supplied by Pilkington Optronics are reported. Research was performed under the Wideband Attenuating Reflective Dielectric Out-of-band Visor Evaluation (WARDOVE) Program whose objective was to define, develop and evaluate reflective dielectric coated out-of-band ALEP visors in the same manner that dye-based absorptive ALEP visors were previously evaluated. Vision performance and human factors evaluations of both reflective dielectric and dye-based LEP spectacles and visors were conducted in the laboratory, in weapon system trainers (WST), and in flight operations. The data presented here document the measured physical performance of the WARDOVE spectacle samples with WD1 and WD2 dielectric coatings prior to any environmental exposure. Discussion of the samples that were evaluated, an overall summary of the physical performance measured, a description of the test methods and instruments, and the detailed data collected are given.
