Apple iPhone X capacities, with a standard offer from ams.

Upon acquiring MAZet in 2016, ams extended its leadership in advanced optical sensing. The acquisition brought to ams several innovative technologies, including spectral sensing. In developing its new AS726X multispectral sensor series (AS7261, AS7262, and AS7263), ams has not only maintained its place in Apple’s ambient light sensor supply chain, it’s also added a new multispectral sensor to its portfolio. With the AS726X series, ams provides a wide array of solutions, from an XYZ sensor and an NIR sensor to a visible light sensor made entirely of interferometric filters.

Offered as three separate devices, the AS726X multispectral sensor series provides three different sensing wavelengths, offering solutions for color matching (i.e. skin tone in the cosmetics industry) and food analysis. All three devices share the same package (4.5 x 4.7 x 2.5 mm) and configuration. 

The AS726X sensors feature interferometric filters, allowing for a more robust, versatile approach than organic filters. In fact, the AS726 provides three different sensing behaviors in six different cells: true-color sensor, visible light sensor, and pure NIR sensor.

This report analyzes ams’ complete multi-spectral sensor portfolio, from sensor die to packaging. This report also includes a complete analysis of the package and sensor die, along with a cost analysis and a price estimate for the device. Moreover, it features a comparison with the ams interferometric multispectral sensor currently found in the Apple iPhone X. Overall, this report covers all of ams’ available technologies in spectral sensing.
