General Description

The AS7263 is a digital 6-channel multi-spectral sensor 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.

This product suits for the following applications:

  • Product authentication
  • Bank note/document validation
  • Chemical analysis
  • Food/Beverage safety
