Hamamatsu Introduces An Ultra-Small MEMS-FPI Spectrum Sensor

Hamamatsu Corporation has announced the release of the C13272, an ultra-small, narrow range spectrum sensor with a MEMS-FPI tunable filter. Fabricated using MEMS (micro-electromechanical systems) technology, the C13272 comes in an 8.9-mm diameter TO-5 package and weighs a mere 1 gram.

The sensor is constructed of a MEMS FPI (Fabry-Perot Interferometer) chip with an InGaAs PIN photodetector covering a spectral response range from 1.55 µm to 1.85 µm. It detects wavelength by tuning the air gap of the silicon-based FPI resonant cavity. This eliminates the grating associated with other spectral sensing methods and, along with its MEMS fabrication, results in a very low profile for integration into compact designs.

The C13272’s spectral response range makes it suitable for materials identification and process control in industrial environments. For conditions where high humidity is present, the C13272 comes in a hermetically sealed package to ensure reliability and maintain a long lifetime.

The MEMS FPI lineup will expand to offer additional package sizes and spectral response ranges. An evaluation kit (C13294) is available to simplify design and development efforts with the C13272.
