Integrating sphere scanner is designed for characterizing the spatial uniformities of integrating spheres. A stable narrow beam of light is pointed at various parts of the sphere surface, covering the whole 4π solid angle. The photometer signal for each direction is recorded producing the sphere responsivity map.
The sphere responsivity map, together with the intensity distribution of the light source under test, can be employed to calculate the spatial non-uniformity correction factor for the luminous flux measurement. This correction reduces the measurement uncertainty of the luminous flux and luminous efficacy measured for the lighting product.  
Our easy-to-use integrating sphere scanner, Hammerhead, is designed to produce extremely stable luminous flux, and to be compatible with various photometer output readout solutions. Moreover, the 16 VDC operating voltage and wireless communication ensure that the system does not require any modifications or additional wiring to the integrating sphere.
The Hammerhead measurement software automates the whole scanning process. The user only needs to select the angular step size and start the scan by pressing a button. The software displays the progress of the scan in real time, and outputs the data in a format directly compatible with fisheye camera method, which measures the intensity distribution of the light source and automatically calculates the spatial non-uniformity correction factor for the luminous flux measurement.
