Description

Fourier transform infrared spectroscopy (FTIR) is a technique which is used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas.

Specification

  • Wavelength range 7,800 – 350 cm-1
  • Resolution 0.5 cm-1 to 64 cm-1
  • Wavelength accuracy 0.1 cm-1 at 1,600 cm-1
  • Signal to noise ratio – 30,000/1 rms, 6,000/1 p-p for a 5 second measurement and 100,000/1 rms, 20,000/1 p-p for a 1 minute measurement
  • Available OPD 0.1, 0.2, 0.5, 1 and 2 cms-1

Services

  • General: Sealed and desiccated optical unit. Vibration isolated baseplate.
  • Interferometer: Improved Michelson interferometer, self-compensating for dynamic alignment changes due to tilt and shear, incorporating high reflectivity first-surface aluminum-coated optics.
  • Source: Long-life source with proprietary hot-spot stabilization. User replaceable.
  • Beamsplitter: Proprietary optimized, multi-layer potassium bromide.
  • Detectors: Electrically, temperature-stabilized fast recovery deuterated triglycine sulfate (FR-DTGS) or lithium tantalate (LiTaO3).
