FTIR Microscopes

The IRT-5000 and IRT-7000 Series of FTIR Microscopes

FTIR microscopy has generally been reserved for measuring specified samples such as small contaminants on polymer films or micro samples transferred to infrared transparent windows. The innovative IRT-5000/7000 Series FTIR Microscopes provide new functions that dramatically improve infrared micro-spectroscopy analyses. These FTIR microscope systems are used together with the FT/IR-4000 or FT/IR-6000 Series spectrometers, offering the most advanced microscopy and imaging systems.

Coupling JASCO’s proven technology for infrared spectroscopy with the most advanced optical design, the IRT-5000/7000 Series offers an ideal solution for the most challenging sample analyses.

FT-IR Micro-Area Analysis - IQ Mapping

The IRT-5000 and IRT-7000 series systems feature a unique and  innovative function for sample analysis – IQ Mapping. This  enables automated multi-point mapping, line mapping and IR imaging analyses of a microscopic area with a manual or auto sample stage and a single element detector. Using a scan mirror the microscope moves the incident light to  specified points, rapidly collecting a full spectrum at each position without moving the sample stage. IQ Mapping can be used to measure and image an area up to 400 x 400 µm using a 16× Cassegrain objective. The combination of IQ Mapping with the automated XYZ stage allows fast mapping and imaging of a wide area.
