Paper Abstract

The overall chip size is less than half of a SD card. The spectral resolution is 3~5 nm for the whole spectral range of 350~1100 nm. The first order diffraction efficiency reaches over 70% at the blaze wavelength, which is at 550 nm. The signal-to-noise ratio of the SpectroChip system is 1000:1 with 50 ms integration time. The stray light is about 0.04%. A total solution is ready to be incorporated into any smart phone, wearable devices, and handheld device systems. With the incorporation of our SpectroChip sensors, hundreds to thousands items related to personal healthcare can be added to the worldwide health analysis cloud platform.
