IRT-7100 Fully Automated FT-IR Microscope

Micro FT-IR has generally been reserved for measuring specified samples such as small contaminants on polymer films or micro samples transferred to infrared transparent windows. Today, JASCO’ s innovative FT-IR Microscopes, the IRT-5000/7000 Series, provide new functions that dramatically improve infrared micro-spectroscopy analyses. These microscope systems can be easily interfaced with the FT/IR-4000 or FT/IR-6000 series spectrometers, offering the most advanced microscopy and imaging systems available in the market. Coupling JASCO’ s proven technology for infrared spectroscopy, accumulated over 50 years, with the most advanced optical design, the IRT-5000/7000 Series offer the best solution for even the most challenging sample analyses.
The IRT-7100 fully automated FT-IR microscope includes a standard mid-band MCT detector, with an option to simultaneously install up to two detectors. It is easily field-upgradable to an IR imaging system by adding an optional linear array detector. The standard automatic sample stage provides wide area mapping and multi-ATR mapping by combining the “IQ Mapping” function with the XYZ auto-stage.

  • Fully automated sample stage with auto focus function as standard
  • IQ Mapping
  • Up to four objectives
  • Dual detector capability
  • Variety of measurement modes (Transmission, reflection, ATR, Grazing Angle Reflection)
  • Field upgrade to IR Imaging System using a linear array detector

FT-IR Micro-area Analysis:
IQ Mapping™

JASCO's new FT-IR microscope systems feature an innovative capability for sample analysis, "IQ Mapping". This function enables automated multi-point mapping, line mapping and IR Imaging analyses of a microscopic area with a manual sample stage and a single element detector. The microscope system automatically scans the specified points or area, rapidly collecting a full spectrum of each point without moving the sample stage.
The IQ Mapping function can provide a measurement of a maximum area of 400 µm square using the 16x cassegrain objective. The combination of IQ Mapping with the automated XYZ stage provides a wide area analysis capability.
