An integrating sphere (10) comprised of a uniform diffusely reflecting spherical cavity (24) having mutually transverse input and output ports (42, 46) and a linear sample transport mechanism (12) secured thereto so that the multiple samples (136) can be brought into registration with the input port, one at a time, without having to open or disassemble the apparatus when a change of a sample (136) is desired. A vacuum tight seal (72) is provided between the cavity (24) and transport mechanism (12) for maintaining the integrity of a vacuum generated within the sphere when attached to source of optical energy. The device is utilized, for example, to test the emissive characteristic such as the relative fluorescence quantum efficiency of a dye sample placed in the path of a monochromatic optical energy source coupled to the input port (42) while having a light detector coupled to the output port (46).
