Precisive® TFS Sensor Platform

The Precisive TFS™ (Tunable Filter Spectrometer) sensor platform consists of a light source, a sample cell (for gases, liquids or solids), a wavelength separating element (spectrometer) and a photo-detector (Figure 1). A wavelength separating element "slices" the wavelength components of the broadband light source which then interacts with the sample molecules. Some of the wavelength components are absorbed and some are transmitted through without any absorption. The resulting spectrum is called absorption spectrum (Figure 2), which acts as "fingerprints" which are used to identify the sample components and/or quantify the composition of the sample.

Precisive TFS™ (Tunable Filter Spectrometer) can now be utilized from UV (Ultra-Violet) through IR (Infra-Red) spectral regions.
