ams AS7341 11 Channel Spectral Sensor
Enabling more precise spectral measurements in a small package
The ams AS7341 is an 11-channel spectrometer enabling new consumer, commercial and laboratory applications including spectral identification, reflection and absorption for color matching, fluid or reagent analysis, passive ambient light measurement and color calibration.
The AS7341 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 of surrounding ambient light conditions, including light source detection.
The ams AS7341 spectral sensor is available in an ultra-low-profile package with dimensions of 3.1mm x 2mm x 1mm, which makes it easy to accommodate mobile phones and other portable devices.
The AS7341 provides extremely accurate and precise characterizations of the spectral content of a directly measured light source, or of a reflective surface, thanks to an abundance of features.
