Compact MEMS-FPI Sensor for Portable NIR Spectrometers

Hamamatsu’s MEMS-FPI spectrum sensors utilize a built-in MEMS Fabry-Perot interferometer and InGaAs PIN photodiode to measure NIR spectra. With their high sensitivity to NIR wavelengths and their compact size, they are suitable for portable devices used to identify materials. For example, as shown in this video, a MEMS-FPI sensor and an NIR light source were integrated into a handheld device to identify textile materials based on their NIR reflection spectra.
