The GladiATR Vision optical design is all reflective, preserving the full spectral range inherent to diamond. For standard mid-IR, the spectral range available with the GladiATR Vision will be 400-400 cm-1. For Far-IR configuration, the spectral range is extended to less than 50 cm-1. The GladiATR Diamond ATR accessory is compatible with the Spectrum 3/Frontier spectrometers. It includes: Base Optics Monolithic diamond crystal plate High pressure clamp with three interchangeable tips Liquids retainer with volatiles cover Purge tubes Purge kit Spectrometer base mount
