ABSTRACT:
A cell for testing passive remote vapor detectors has a cell body with a blackbody radiation source attached to a first end and a window attached to a second end. The blackbody radiation source and the window seal the first and second ends, so that a hazardous vapor can be easily contained. With this arrangement, it is easy to account for the effects of the window on output radiation and thus to calculate radiance and temperature quantities of interest.
