Integrating sphere source with spherical illuminated field for the uniformity and white balance of fisheye cameras Uniformity adjustment of fisheye cameras Digital cameras with fisheye and super-wide angle lenses are characterized by viewing angles of up to >180°. Since these cameras map a hemispherical image in front of the objective lens on the image plane, reference light sources with a hemispherical illuminating field are required for uniformity matching. Please see our technical article "Integrating sphere source for homogeneity and white balance of fisheye cameras". Integrating sphere source with spherical illuminated field Integrating sphere based ,uniform light sources‘ offer luminous fields with highly uniform light distribution. In order to provide Fisheye cameras with a hemispherical illuminating field for uniformity matching, the camera must be placed in the center of the integrating sphere. This requirement significantly increases the design complexity of the integrating sphere ant its associated light sources and baffles. White balance with different light spectra Together with the uniformity adjustment, a white balance can be set for color cameras. In order to optimize the camera’s performance under different lighting conditions, the uniformity and white balance should be carried out at more than one color temperature.
