The 80251 MIR8025 IR Fourier Spectrometer is for when you don’t have a traditional analytical application for an FT-IR and/or you’re concerned about flexibility. This version uses a CaF2, Beam Splitter for a 0.7 to 8.3 µm spectral range. We designed it specifically for Researchers and OEMs who want an instrument easily adaptable to their special needs, at an economical price, and without compromise in performance. The MIR8025 has selectable resolution starting with 0.5 cm-1, 0.25 m A.U. S/N ratio, and a very broad spectral range. The MIR8025 uses a scanning Michelson Interferometer. Our optical layout includes corner cubes and a retro-reflector. The unique layout is immune to tilt and shift. The retro-reflector and beam splitter are mounted together, providing accurate alignment while desensitizing the system to vibrations and temperature variations. This unibody approach to the beam splitter makes for easy interchangeability with a minimum of realignment required.
