The LIGHTSOURCE01EVM is able to replicate sunset and noon lighting spectra. Refer to the following figure for the spectral response of the light source for the sunset and noon modes.

LIGHTSOURCE01EVM Noon Spectral ResponseFigure 1-2 Noon Spectral Response
LIGHTSOURCE01EVM Sunset Spectral ResponseFigure 1-3 Sunset Spectral Response

For both spectra, the EVM is highly stable, with variations in output at maximum intensity kept to <±1%.

The light source also maintains high uniformity, with <±1% variation for a 1 inch diameter spot 12 inches away from the source. This means that the light intensity across the entire spot is consistent, with minimal variation from the center of the spot to the edges. This high uniformity is designed for the calibration of ALS and color sensors, which demand a highly stable and uniform light source.
