ams AS7261 Spectral Sensing Engine
The AS7261 integrates Gaussian interference filter technology to enable chromatic white color sensor which provides direct XYZ color coordinates consistent with the CIE 1931 2° standard observer color coordinates. Additional mapping of XYZ coordinates to the x, y (Y) of the 2-dimensional color gamut and scales of the CIE 1976 u’v’ coordinate system, providing accurate correlated color temperature (CCT) measurements and color point deviation from the black body curve for white light color in the ∆u’v’ coordinate system. A near-IR channel and LED drivers with programmable currents increase application flexibility, including support for electronic shutter applications. Control and spectral data access is implemented either through either the I²C virtual register set, or via the serial UART enabling use of the high level smart spectral command set.
ams AS7263 6-Ch NIR Spectral Sensing Engine
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.
ams AS7264N Consumer Grade Smart XYZ + Bio-Blue + NIR Sensor
The AS7264N provides direct XYZ sensor data which conforms to the tri-stimulus standard observer color response of the human eye. In addition, two channels added for measurement of blue spectrum light, plus a near-IR channel enables additional application flexibility. LED drivers with programmable currents are provided for electronic shutter applications. The AS7264N integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology and is packaged in 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 an I²C register set.
ams AS7341 – 11-Channel Spectral Color Sensor
AS7341 is an 11-channel multi-spectral sensor for color detection and spectral analysis applications. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. 6 channels can be processed in parallel by independent ADCs while the other channels are accessible via a multiplexer. 8 optical channels cover the visible spectrum, one channel can be used to measure near infra-red light and one channel is a photo diode without filter (“clear”). The device also integrates a dedicated channel to detect 50Hz or 60Hz ambient light flicker. The flicker detection engine can also buffer data for calculating other flicker frequencies externally. The NIR channel in combination with the other VIS channel may provide information of surrounding ambient light conditions (light source detection). The device can also be synchronized to external signals via pin GPIO. AS7341 integrates filters into standard CMOS silicon via Nano-optic deposited interference filtertechnology and its package provides a built in aperture to control the light entering the sensor array. Control and Spectral data access is implemented through a serial I²C interface. The device is available in an ultra-low profile package with dimensions of 3.1mm x 2mm x 1mm.
