Integrating sphere scanner Hammerhead is designed for characterizing the spatial uniformity of the integrating sphere. A beam of light is directed at all 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.  
Hammerhead is a fully automated integrating sphere scanner which is easy and convenient to use. Moreover, the 12 VDC operating voltage and wireless control ensure that the system does not require any additional wiring or modifications to the integrating sphere. The scanner is designed to produce extremely stable luminous flux, and to be compatible with your existing photometer, further reducing measurement uncertainty compared to dedicated signal readout solutions.
The Hammerhead measurement software automates the whole scanning process. The user only needs to select the angular step size and start the scan. The software displays the resulting responsivity map during the scan, and at the end of the measurement outputs the data in a format directly compatible with the fisheye camera method which measures the intensity distribution of the light source and automatically calculates the spatial non-uniformity correction factor for luminous flux measurements.
