Abstract

An exposure indicating device disposed in a respirator system. The exposure indicating device comprises a diffractive optical element. The exposure indicating device comprises a material having an index of refraction that changes as a function of exposure to a chemical vapor, where the exposure indicating device provides an optical signal that changes in optical property as a function of exposure to the chemical vapor.
