Description
Summary:This report presents a discussion of laser eye-protection filtering materials. Four classes of filters are evaluated for immediate and future filtering capabilities. Salient features required for near-term multiwavelength filtering are discussed in general, and the effectiveness of several filter materials as laser protection is assessed. Spectral illuminances for the most promising eye-protection filters are computed for representative day- and night- lighting conditions to approximate visual acuity. (RH)
