Principle of instrument

The light emitted by the light source is divided into two beams by the beam splitter (similar to the semi-transparent semi-reverse mirror), one beam reaching the moving lens and the other beam reaching the fixing lens. Two beams of light are reflected by the fixed mirror and the moving mirror and then return to the beam splitter, and the moving mirror moves in a straight line at a constant speed, so the two beams of light after the beam splitter form the light path difference and produce interference. After the beam splitter meets, the beam splitter passes through the sample pool, and reaches the detector through the sample, and then the signal is processed by Fourier transform to finally obtain the infrared absorption spectrum of transmittance or absorbance with wavelength or wavelength.
