More Information
Summary:A flexible filter for use in filtering wavelengths of light that interfere with night vision awareness systems is disclosed. A filtering material is applied to a first flexible film in a substantially liquid form and is cured thereto using ultraviolet light. The filtering material filters wavelengths of light between about 610 and 930 nanometers when cured. A second flexible film is temporarily held in place by a support member. The second flexible film is applied to the cured filtering material and is fused thereto using a combination of increased temperature and pressure for a predetermined time. The first and second flexible films are made of polyurethane.
