Camera Uniformity Test – KT Mini Sphere

The KT Mini Sphere is a uniform light source and integral intensity detector  based on the integrated sphere concept. Combined with precise current amps and photodiodes for internal adjustment, it is  capable of accurate intensity and color correlated temperature (CCT) control. The KT Mini Sphere can also represent light with different intensities. With our calibration and adjustment procedure we are able to allow nearly step less dimming (16bit resolution of current amps),  as well as calibrations for different CCTs.
