CI Systems offers a cost effective highly uniform integrating sphere for the VIS-SWIR wavelength range. The system provides uniform radiance for testing of cameras that operate in a wide spectral range. Now offering three standard sizes: 1”,2” and 4” output port diameters. Using a highly reflective internal coating the system is able to produce uniformity of over 98% at its output port. A continuous variable output is achieved using an high resolution motorized attenuator. Increased dynamic range can be achieved using optional neutral density filters. Using a variety of light sources the system can be adapted to provide higher Luminance intensities and a wider dynamic range.
