NanoLambda has developed a $10 spectrometer-on-a-chip that's suitable for use on a wide range of consumer devices. The Spectrum Sensor measures individual wavelengths and is accurate to 1 nm with 10nm resolution, allowing NanoLambda to selectively pass light through nanostructures to determine their makeup. The company used traditional wafer processes to create 5mm x 5 mm x 2mm thin nanofilter arrays. Nine hundred of these arrays can be stacked to create a millimeter-scale chip that can be embedded into various Internet of Things devices.
