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.
Figure 1-2 Noon Spectral Response
Figure 1-3 Sunset Spectral ResponseFor both spectra, the EVM is highly stable, with variations in output at maximum intensity kept to <±1%.
Figure 1-4 Sunset Source Stability
Figure 1-5 Noon Source StabilityThe 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.
