Solid State Flat Fielding Sources from 2800K to 7500K

Spectra-CT Color Tunable Spectral Calibration Sources

Save money and save space. The Spectra-CT produces multiple CCTs and high dynamic range for multilevel testing. Engineered for their high performance requirements in image sensor production testing and calibration, they are ideal for both R&D and manufacturing applications.

Spectra-CT integrating sphere based uniform light sources utilize warm white and cool white LEDs controlled by a high-precision programmable DC power supply. With the active cooling system inside, the output is kept stable over a broad range of luminance levels up to 50,000 cd/m2.

Simple and convenient software is provided together with the system for CCT selection, luminance adjustment together with related system information. For advanced applications such as multi-system integration, software API is available.

Select from three CT-1000 product models ranging from 5 cm luminance port to 20 cm luminance port
