Lida-20 Fourier Transform Infrared Spectrometer

Product Introduction
The Lida-20 Fourier Transform Infrared Spectrometer is a compact and reliable FTIR spectrometer designed for routine material identification, qualitative analysis, and research applications. With convenient installation, simple operation, and easy maintenance, it is widely used in biomedicine, materials science, petrochemicals, food safety, environmental protection, quality control, and scientific research.
The Lida-20 uses a Michelson interferometer to modulate infrared radiation into an interferogram. After the infrared beam passes through the sample, the detector collects the sample-related information. The computer then performs a Fourier transform to generate the infrared spectrum for qualitative identification and spectral analysis.

• Modular structure simplifies maintenance and component replacement.

Working Principle
The Lida-20 Fourier transform infrared spectrometer operates according to the Michelson interferometer principle.
1. The infrared source emits broadband infrared radiation.
2. The Michelson interferometer divides and recombines the infrared beam to generate an interference signal.
3. The modulated infrared beam passes through or reflects from the sample.
4. The detector receives the interferogram containing sample-specific absorption information.
5. The software applies a Fourier transform to convert the interferogram into an infrared spectrum.
6. The resulting spectrum is compared with reference spectral libraries for material identification and analysis.
