Paper Abstract

An advanced optical filter to protect the eye from laser beams is opaque to the entire visible spectrum except for three narrow bands, one in the blue, one in the green, and one in the red. A typical such filter transmits only about 6% of the incident light; yet vision through it is bright and clear and in full natural color.
