MEMS-FPI spectrum sensor
The MEMS-FPI spectrum sensor C14273 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 1750 to 2150 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: 1750 to 2150 nm
-Ultra-compact: TO-5 package
-Ultra light: 1 g
-Hermetically sealed package: high reliability under high humidity environment
-Built-in band-pass filter for cutting off wavelengths outside the spectral response range
A demonstration module with a built-in MEMS-FPI spectrum sensor and near infrared light source measured the reflection spectrum of the plastics. From the spectrum obtained, it is possible to distinguish the component of plastic.
