AS7341-DLGM

AS7341-DLGM is an 11-channel multi-spectral digital sensor. It enables new consumer, commercial, and laboratory applications including spectral identification, reflection, and absorption for colour matching, fluid or reagent analysis, passive ambient light measurement, and colour calibration. The spectral response is defined by individual channels covering approximately 350nm to 1000nm with 8 channels centered in the visible spectrum (VIS), plus one near-infrared (NIR) and a clear channel. The NIR channel in combination with the other VIS channels may provide information on surrounding ambient light conditions, including light source detection. The application includes high-precision reflective colour point and spectral measurements, fluid colour, turbidity or reagent-based constituent analysis, spectral power distribution and passive ambient CCT measurement for home and building automation, and high-end display colour management.
