Laser eye protection is important due to the availability of laser sources (continuous and pulsed) over a broad range of wavelengths. The military uses many laser systems (e.g., training devices, range finders, target designators, communications devices) that emit potentially eye damaging radiation. Because personnel risk exposure to these devices, a growing need exists for eye protection at a variety of wavelengths for both CW and pulsed sources. The objective of this proposal is to develop laser eye protection coatings using transparent metallo-dielectric multilayer stacks. These stacks provide a high transparency window in the visible spectrum but block both UV and IR light. The coatings have sufficient optical density to protect the eye from damage by IR laser radiation threats. In the Phase I effort we built and tested stacks on both rigid and flexible substrates to provide LEP technology for a wide variety of applications. The Phase II work will integrate these materials into polycarbonate visors. Test samples will undergo extensive optical and physical testing by Revision Eyewear to demonstrate that these visors meet the ballistic, optical and quality standards required by the military. We will deliver test visors incorporating the proposed technology with supporting performance data to the customer. BENEFIT: This LEP technology solution will create a passive barrier that protects against both continuous wave (CW) and pulsed laser emissions, will be compatible with incorporation into a polycarbonate visor during molding, and not be angularly dependent. Because of dramatically increased use of military laser systems The U.S. Air Force, Army, and Navy all have requirements for increased requirements for LEP for personnel. Potentially any commercial field that uses lasers or laser eye protection (e.g., medical/dental laser surgery, lab technicians, welding, manufacturing, and laser research) can benefit from develop of LEP technology.
