Depending on the performance, traditional spectrometers sell for $5,000 to as much as $100,000 per instrument. Si-Ware Systems (SWS) says that its MEMS based Fourier transform infrared (FTIR) spectrometer module enables instrument makers to sell their products at well below the current price levels. There are different levels of performance and capabilities for spectrometers, and instruments for higher spectral ranges are more costly. For example, mid-infrared (MIR) spectrometers tend to need cooled photodetectors which adds significantly to the cost. The performance of Si-Ware’s module is not as good as the lab-grade spectrometers. However, the company says that its module is good enough for many other applications.
