Abstract: An improved light source for use in an opacity monitor (transmissometer) that reduces the variation in light intensity across a projected light beam to enable a more accurate and stable method for measuring the opacity of gases in a stack/duct, especially at low values (e.g., <10%) of opacity while operating within specific performance requirements.
