The VERTEX 80 and the VERTEX 80v vacuum FT-IR spectrometers are based on the actively aligned UltraScan™ interferometer, which provides PEAK spectral resolution. The precise linear air bearing scanner and PEAK quality optics guarantees the ultimate sensitivity and stability. The VERTEX 80v is an evacuated optics bench that can eliminate atmospheric moisture absorptions for ultimate sensitivity and stability, enabling demanding experiments such as high resolution, ultra-fast rapid scan, step-scan, or UV spectral range measurements.
