The FT/IR-4000 and FT/IR-6000 Series of FTIR spectrometers redefine the this powerful, easy-to-use technique. Each compact model offers reliable operation with some of the highest performance parameters in the industry. Including a sealed interferometer with corner-cube mirrors and AccuTrac™ DSP technology for rapid and accurate tracking of mirror position and velocity for optimum wavenumber precision and signal-to-noise performance. The FTIR Series includes the intuitive Spectra Manager™ Suite with integrated search software solution, FTIR Spectrometers System Features Interferometer The interferometer is manufactured as a solid cast aluminum block and is completely sealed. The FT/IR-4000 uses a 45 deg Michelson interferometer and the FT/IR-6000 uses a 28 degree Michelson interferometer. A near frictionless bearing (without the need for a gas supply) supports the moving mirror which is driven by a ‘voice coil’ for accurate vibration free movement. Counter Strike 1.6 Non Steam Cheats Chomikuj. Laser tracking of the moving mirror is made using Accutrac™ with the latest in digital signal processing.
