Ultra-compact near infrared spectrum sensor that integrates MEMS tunable filter and photosensor, built-in band-pass filter
The MEMS-FPI spectrum sensor is a ultra-compact sensor that houses a MEMS-FPI (Fabry-Perot Interferometer) tunable filter that can vary its transmission wavelength depending on the applied voltage and InGaAs PIN photodiode in a single package. The spectral response range is 1550 to 1850 nm. It is suitable for installation in simple, compact instruments for measuring material absorbance and the like.
