综述
The AS7265x family incorporates 3 chips to deliver an 18-channel multi-spectral sensing array covering wavelengths from 410nm to 940nm. The AS72651 covers NIR wavelengths from 600nm to 870nm and serves as the master controller for the set. When combined with the AS72652 (spectral response from 560nm to 940nm) and the AS72653 (spectral response from 410nm to 535nm) the full set delivers 18-channels with FWHM of 20nm. The device family integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology in LGA packages, and each AS7265x device has two integrated LED drivers with programmable current and which can be timed for electronic shutter applications.

Demo Kit for AS7265x
AS7265xDemoKit
The AS7265x Demo Kit is a Windows PC-hosted evaluation environment, designed to provide the user an quick-start approach to spectral sensing. The demo kit consists of the evaluation board, USB-UART cable with Micro-USB connector, and a USB stick which includes drivers, documentation and graphical user interface. The demo board includes unpopulated device pads for the installation of standard LED light sources suited to the specific spectral needs of the application. By default, the LED pads are unpopulated. If necessary also a housing can be provided on request.
