title: General formulation for the integrated effective emissivity of any axisymmetric diffuse blackbody cavity.
abstract: A general method for the precise evaluation of the integrated effective emissivity of a diffuse frustrum-cone cavity is formulated. The mathematical expressions derived can be applied to calculate precisely the integrated emissivity of, or the irradiance of a detector from, any practical axisymmetric cavity with circular symmetry. Some typical values of integrated emissivity are presented for cylinders, cylindro-cones, double cones, and cylindro-inner-cones, and comparisons between such cavities are made.
