Great 20 Fourier Transform Infrared Spectrometer is a product independently developed by our company. It has the characteristics of convenient installation, simple use, and convenient maintenance. It is an indispensable spectral analysis instrument for industries such as material science, biomedicine, petrochemical industry, and food safety. At the same time, it is also a necessary laboratory analytical instrument for related majors in universities, research institutes and other institutions. Since its listing, it has occupied a dominant position in the domestic market and won the support and trust of the majority of users.

B. Experimental principle

Using the working principle of interferometer interference frequency modulation, the light emitted by the light source is converted into interference light by Michelson interferometer, and then the interference light is irradiated on the sample, and the receiver receives the interference light with sample information, and then the computer software undergoes Fourier transform The spectrum of the sample can be obtained.
