MEMS-FPI spectrum sensor



Ultra-compact near infrared spectrum sensor that integrates MEMS tunable filter and photosensor, built-in band-pass filter

The MEMS-FPI spectrum sensor C14272 is a ultra-compact sensor that houses a MEMS-FPI (Fabry-Perot Interferometer) tun-able 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 1350 to 1650 nm. It is suitable for installation in simple, compact instruments for measuring material absorbance and the like.

-Built-in Hamamatsu InGaAs PIN photodiode single element chip
-Spectral response range: 1350 to 1650 nm
-Ultra-compact: TO-5 package
-Ultra light: 1 g
-Hermetically sealed package: high reliability under high humidity
-Built-in thermistor
-Built-in band-pass filter for cutting off wavelengths outside the spectral response range
