Key Features

Precise standard-illuminant reproduction: 32 independent LED channels reproduce Planckian-radiator spectra over 2000K-20000K. Independent channel control provides 60000 illuminance levels, automatic spectral switching in a preset sequence and single-channel minimum illuminance below 1lux for high- and low-light tests. High color rendering and uniformity: Ra>95 reproduces colors faithfully, while brightness uniformity >90% at the sphere center supports stable, consistent measurements. A large 150mm sphere opening supports a 220° field of view for ultrawide-angle and complex imaging tests. Spectrum: 380nm-980nm. Correlated color temperature: 2000K-20000K. Opening diameter: 150mm. Color rendering index: Ra>95. The 32 independent channels reproduce Planckian spectra, such as CIEA, and CIED-series daylight spectra over 2000K-20000K. Each channel has 60000 illuminance levels; single-channel switching takes 30ms and multichannel spectral switching completes within 70ms. Preset sequencing is supported, with single-channel minimum illuminance below 25lux for high/low-light tests. A 7-inch touchscreen provides intuitive operation; C/C++API and GUI interfaces support integration and automation.
