FTIR engine
C16511-01
High-speed and compact near infrared spectrometer that can be incorporated into inline process
The C16511-01 Fourier transform infrared spectrometer (FTIR) engine is a compact Fourier transform near infrared spectrometer. A Michelson optical interferometer, a control circuit, and a calculation circuit are built into a compact enclosure. Spectrum and absorbance can be measured by connecting a PC via Ethernet. It can be applied to real-time measurement performed on site without bringing the measurement sample into the analysis room as well as continuous monitoring. In addition, Ethernet communication offers higher communication speed and durability than USB communication, making it applicable to FA devices.
The optical interferometer has a built-in light input section, beam splitter, fixed mirror, movable mirror (ϕ3 mm), and photodetector. The photodetector acquires light intensity signals that vary depending on the position of the movable mirror. The optical spectrum is obtained by processing (Fourier transform) these light intensity signals.
The FTIR engine has a built-in semiconductor laser (VCSEL: vertical cavity surface emitting laser) for monitoring the movable mirror position, which allows spectrum measurement with high wavelength accuracy.
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.
