General Description
The AS7263 is a digital 6-channel spectrometer for spectral
identification in the near IR (NIR) light wavelengths. AS7263
consists of 6 independent optical filters whose spectral
response is defined in the NIR wavelengths from approximately
600nm to 870nm with full-width half-max (FWHM) of 20nm. An
integrated LED driver with programmable current is provided
for electronic shutter applications.
The AS7263 integrates Gaussian filters into standard CMOS
silicon via Nano-optic deposited interference filter technology
and is packaged an LGA package that provides a built in
aperture to control the light entering the sensor array.
Control and Spectral data access is implemented through either
the I²C register set, or with a high level AT Spectral Command
set via a serial UART.
Applications
The AS7263 applications include:
• Product authentication
• Bank note/document validation
• Chemical analysis
• Food/beverage safety
