AMS AG has announced the AS7262 visible range sensor and the AS7263 NIR sensor, each providing six calibrated spectral channels.
The multispectral sensors employ a new fabrication technique which enables nano-optical interference filters to be deposited directly on the CMOS silicon die with extreme precision. This interference filter technology offers precise and reproducible filter characteristics which are stable over both time and temperature. They are also much smaller and more cost-effective than the components typically used in today’s spectral analysis instruments.
The AS7262 six-channel visible light sensor with integrated intelligence provides a calibrated digital output over an I2C or UART interface. It measures light intensity at 450, 500, 550, 570, 600 and 650 nm. The AS7263 detects 610- , 680-, 730-, 760-, 810- and 860-nm IR signatures. Both devices include an electronic shutter with LED drive circuitry, which means that device designers can accurately control the light source and the spectral sensing functions with a single chip.
