Types of IR Instrumentation

IR spectroscopic instrumentation is grouped into multiplex (Fourier transform) and nonmultiplex (dispersive) methods. These two categories reflect the means by which the spectra are acquired.

Different types of IR instruments are available dispersive grating spectrophotometers, FT instruments, and nondispersive photometers. Until the 1980s, and the... 

There are two major types of IR instruments one type detects IR emitted from objects, such as IR cameras and the other detects IR radiation absorbed by objects, such as IR spectroscopy. The uses of the IR technique in the analytical and detection field are based on IR absorption characteristics at specific wavelengths by the substances of interest.
