  1. An apparatus that records the optical spectrum of emissive materials as a function of polar coordinate angles is reported. The ability of the device to characterize the directive gain of a light source over the optical spectrum is demonstrated. The angular emission profile of an electrically driven LED with a hemispherical diffuser cap was measured. In addition, the device was used to characterize optically pumped materials exhibiting both fluorescence and amplified spontaneous emission, demonstrating its versatility for diverse emissive systems.
