AS7265x Smart 18-Channel VIS to NIR Spectral_ID 3-Sensor Chipset
The AS7265x chipset is a sophisticated 18-channel multispectral sensor solution designed for spectral identification across the visible to near-infrared (NIR) spectrum. It comprises three devices: AS72651 (master), AS72652, and AS72653. Each sensor features six independent on-device optical filters with spectral responses ranging from 410nm to 940nm with a Full Width at Half Maximum (FWHM) of 20nm. This chipset offers a compact, integrated solution with built-in LED drivers for electronic shutter applications, eliminating the need for additional signal conditioning. The AS7265x is ideal for applications requiring precise material analysis, product authentication, anti-counterfeiting, and safety checks.
