IMAGING Visible MEMS

High sensitivity micro-spectrometer with broad spectral coverage.

For a long time, spectral analysis of materials has been reserved for academic research laboratories. The arrival of new small and cheap sensors allows their integration into new products and industrial environments to increase the quality of production and product control.

The spectrum data measured by the Hamamatsu C12880MA micro-spectrometer is compatible with the spectrum data measured by conventional optical spectrum analyzers, which facilitates the use of this device without needing to create a database.
The C12880MA is a 2.5cm3 spectrometer head that could be integrated into a wide range of measurement and quality control equipment. Working with wavelengths between UV and near IR, 340-850nm, the micro-spectrometer can be used for food inspection, biometry, water quality, light testing and light level measurements.

The CMOS linear image sensor provides spectral resolution of 15nm. Moreover, the hermetic package allows its use in moist atmosphere. The small package integrates the light sensor and diffractive elements, here a reflective grating and slit.

The report contains a detailed physical analysis with process description and manufacturing cost analysis. It also includes a full comparison with the NanoLambda NSP32 and Consumer Physics SCiO spectrometers.
