Custom/OEM FTIR Spectroscopy Solution (IRE-1)

The IRE-1 Engine is an FTIR solution designed and manufactured for your application. Based on the IRD 3, a dedicated vapor phase GC-IR detector with over 25 years of market success, the IRE-1 has a proven track record not typically found in new products. The IRE-1 will assist customers with the development of conceptual spectrometers and with the modernization of existing FTIR spectrometers.

  • Designed and built for your application
  • Small footprint
  • Mid-IR and Near-IR configurations
  • High-performance electronics
  • USB interface
  • Complete data analysis software



The IRE-1 consists of specific hardware items that act as a foundation that can be expanded or subtracted based on the needs of the customer. The standard hardware in the IRE-1 is as follows.

  • Proprietary air-cooled conical infrared source designed to simulate a true black body and maximum emissivity of mid, far and near-infrared energy
  • Michelson interferometer with automatic, computer controlled alignment, digital servo loop for accurate control of mirror velocity, voice coil magnet drive with diaphragm bearing
  • HeNe laser reference: 633nm 
  • State of the art electronics designed to take full advantage of the technology developed to support today’s high-performance audio marketplace
  • Optical baseplate
  • Purge cover
  • IR detectors, sampling mirrors and accessories, Essential FTIR Software and custom designs are optional
