FOLI30V Vacuum FT-IR Spectrometer

FOLI30V vacuum Fourier transform infrared spectrometer is a new high-end research-grade infrared spectrometer from INSA optics. The FOLI30V has a vacuum design for optical bench and sample chamber, the user does not have to worry about the effect of water vapor and carbon dioxide on the weak absorption signal, at the same time, the design can improve the throughput of the spectrometer. The vacuum FT-IR spectrometer is widely used in nano surface analysis, polymer industry, materials science, pharmaceuticals, semiconductors and catalysis etc.

Features
