Specification
The FT/IR is a powerful Mid-IR FTIR spectrometer (wavenumber range 7800 to 350 cm-1), with many features that you find in a research grade instrument, such as non-hygroscopic KRS-5 windows to prevent damage to the interferometer, a Peltier stabilized DLaTGS detector and a high output ceramic source for maximum sensitivity. Permanent optical alignment is guaranteed by corner cube (retro-reflective) mirrors with auto-alignment for maximum energy. With a resolution of 0.7cm-1 and a S/N greater than 25,000:1.
