This compact module has a built-in light source, control circuit, and MEMS-FPI spectrum sensor consisting of an InGaAs PIN photodiode and MEMS-FPI (Fabry-Perot Interferometer) tunable filter which can vary its transmission wavelength by changing the applied voltage. Spectrum and absorbance can be measured by connecting a PC via USB. The product includes evaluation software with functions for setting measurement conditions, acquiring and saving data, drawing graphs, and so on. Furthermore, the dynamic link library (DLL) function speciﬁcations are disclosed, so users can create their original measurement software programs.
- Compact, thin case
- MEMS-FPI spectrum sensor and light source are installed.
- External power supply not necessary: USB 2.0 bus powered
- Transmission wavelength shift due to the ambient temperature change is corrected.
- High-speed measurement
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.
