The ISP 1000 integrating sphere from Instrument Systems GmbH was designed with a 1-m diameter for precise measurement of total radiant power and luminous flux of lamps. Suitable for larger, powerful LED modules with applications in solid-state lighting, the sphere’s design minimizes the effect of compromising influence caused by baffles and ports to permit more accurate measuring results. Samples can be placed inside the design on a height-adjustable stage or in a lamp post with suspended or upright configuration, enabling the flux to be determined in 4π. Light radiation also can be launched from outside through a side port to allow heat dissipated from large LED modules to be kept out of the sphere.
