Ames Semiconductor (ams AG, SIX Swiss Exchange: AMS), a leading supplier of high-performance sensor solutions and analogue ICs, today announced the world's first cost-effective, multi-channel spectroscopic on-chip sensor solution, opening the way for a new generation of spectroscopic analysers for consumer and industrial applications. The increasing integration of sensors into smartphones and tablets has created a new wave of mobile applications, and the introduction of the AS7262 and AS7263 enables the widespread use of chip-scale spectroscopy, revolutionising spectroscopy for both industrial and consumer applications," said Jean Francois Durix, director of marketing for Emerging Sensor Systems at Amax Semiconductor. The introduction of the AS7262 and AS7263 has revolutionised spectral sensing innovation for industrial and consumer applications by enabling widespread use of chip-scale spectral analysis. The new spectral sensing solutions dramatically reduce the cost and solution size of spectral analysis and are widely applicable to applications such as food safety, product certification, and routine testing, helping to better protect people's health and the environment in which they live."
Packaged in a small 4.5 x 4.4mm array package, both the ultra-low power AS7262 visible sensor and AS7263 near infrared sensor offer six calibrated spectral channels. Extremely competitively priced, this new multi-channel spectral sensor opens the door for testing and use in a variety of applications in consumer products and real-world applications. Its primary solutions include material and product certification, product quality and integrity, and material content analysis in the near infrared (NIR) and visible spectra.
The multispectral sensor uses a new fabrication technique that allows nano-optical interference filters to be extremely precisely attached directly to CMOS silicon wafers. The interferometric filter technology used in this sensor is extremely accurate and stable, independent of time and temperature, and is smaller and more cost-effective than the components commonly used today in all types of spectral analysis instruments.
The intelligent AS7262 six-channel visible light sensor provides calibrated digital outputs via an I2C or UART interface. It measures the intensity of light in the visible range at six different wavelengths: 450 nm, 500 nm, 550 nm, 570 nm, 600 nm, and 650 nm, while the AS7263 detects the infrared characteristics of the near-infrared spectrum at 610 nm, 680 nm, 730 nm, 760 nm, 810 nm, and 860 nm. Both products include an electronic shutter with LED drive circuitry, meaning that device designers can accurately control the light source and spectral detection functions from a single chip.
The new multispectral sensors feature a small footprint and low power consumption, which measurement equipment OEMs can leverage to easily enable new product development. For example, bulky lab-grade analytical equipment can now be replaced by convenient handheld devices. In factories, where samples produced today have to be sent from the production line to the laboratory for chemical analysis, future quality testing will be possible on the production line with new compact and robust spectral analysers based on multispectral sensors.

AS7341 11-channel spectral sensor
ams' 11-channel spectrometer for spectral recognition and colour matching applications
The ams AS7341 is an 11-channel spectrometer for spectral recognition and colour matching applications in mobile devices. The spectral response is defined in the wavelength range from approx. 350nm to 1000nm. Six channels can be processed in parallel by independent ADCs, while the other channels are accessed via a multiplexer. Eight optical channels cover the visible spectrum, one channel can be used to measure near-infrared light, and one channel is a photodiode without a filter ("transparent").
The device also incorporates a dedicated channel to detect ambient light flicker at 50 Hz or 60 Hz. The flicker detection engine can also be used to buffer the data when other flicker frequencies are externally calculated. the NIR channel in combination with the other VIS channels provides information on the ambient light conditions (light source detection). The device can also be synchronised with external signals via pin GPIOs.The AS7341 integrates a filter into a standard CMOS wafer via nano-optical deposition interference filter technology, and the package provides a built-in aperture to control the light entering the sensor array. Control and spectral data access is achieved via a serial I2C interface. The device is available in an ultra-thin package measuring 3.1 mm x 2 mm x 1 mm.

The following is the sensor module AS7343:
Product Description:
The 14-channel AS7343 chip is packaged in a 3.1mm × 2mm × 1mm flat package and, like a spectrometer, the sensor is used to measure the spectral power distribution of a light source or reflected light. The sensor has 12 equally spaced measurement channels in the visible spectrum, adjacent to a near-infrared (NIR) channel, and an XYZ function. Unlike its predecessor, the AS7341, the AS7343 combines a multi-channel spectral sensor with XYZ technology. the XYZ channels are tightly aligned to the CIE 1931 XYZ colour space, which is the standard model for the human eye's perception of colour. the AS7343 produces direct XYZ values, i.e., colour co-ordinates, which give the user flexibility in choosing whether to perform a full-spectrum analysis or a simple colour scan. The AS7343 has the flexibility to choose whether to perform full spectrum analysis or simple colour scanning.
The AS7343 generates unique spectral features for any light source and reflected light, and up to six channels can be used simultaneously for more flexible performance. This new model is four times more sensitive than its predecessor, the AS7341, for better colour balance perception and signal analysis across the spectrum, while automatic ADC reconstruction provides faster multi-channel readings.
In applications such as plant lighting, a single AS7343 sensor is often sufficient to provide high-resolution measurements of spectral power distribution. If higher resolution is required, the filter response curves of two or more AS7343 sensors can be configured to partially overlap, reducing the bandwidth of each channel and increasing the measurement resolution. This technique can also be used with the AS7341. In addition, the AS7343 sensor can perform chromatography on liquids or materials to support horticultural growing applications such as the measurement of plant chlorophyll concentration.
Another scenario for the AS7343 is its application in smoke and heat alarms for the detection of smoke spectral signatures.The spectral analysis of the AS7343 enables the smoke sensor to distinguish between different types of smoke from burning wood, plastic or water vapour.
Product Features:
-14 optical channels distributed on the VIS, including XYZ and one NIR.
-Includes 2 additional channels: unfiltered channel, scintillation channel
-6 parallel ADCs for signal processing
