AS72651-BLGT

AS72651-BLGT is a smart 18-channel VIS to NIR spectral- ID 3-sensor chipset with an electronic shutter. The multispectral sensor can be used for spectral identification in a range from visible to NIR. Every of the three sensor devices has 6 independent on-device optical filters whose spectral response is defined in a range from 410nm to 940nm with FWHM of 20nm. Using the AS7265x chipset requires the use of firmware. It must be loaded into a serial flash via a UART interface. The information about the conditions of the performed calibration (for example light source, gain, integration time) can be found in the table of optical characteristics of the respective component. Any operation other than these conditions might require a new calibration in the application. Application includes product/brand authentication, anti-counterfeiting, portable spectroscopy, product safety/adulteration detection, horticultural and specialty lighting, and material analysis.
