Ultra-compact NIR sensor

Hamamatsu’s C14273 MEMS-FPI spectrum sensor weighs just 1 g and the ultra-compact sensor houses a MEMS Fabry–Perot interferometer (FPI) that can vary its transmission wavelength depending on the applied voltage and an InGaAs PIN photodiode in a single TO-5 package. Its spectral response range is 1750–2150 nm.
