The IRT-5000 Series of FTIR microscopes provides new functions that dramatically improve infrared micro-spectroscopic analysis. The IRT-5000 microscope is used with either the FT/IR-4000 or FT/IR-6000 Series spectrometers, combining both micro and macro FTIR measurement, offering the most advanced microscopy and imaging systems. The systems are typically used in the mid-IR for materials identification and forensic analysis or in the near- and far-IR for more fundamental research.
The IRT-5000 FTIR Microscope includes an automatic carousel with a choice of cassegrains and refractive elements for observation and measurement. A mid-band MCT detector is included (with option for a high sensitivity peltier cooled DLaTGS detector). Up to two detectors can be installed to expand the spectral range of the microscope. The unique IQ Mapping function can be used for Transmission/Reflectance or ATR mapping without requirement to move the sample stage. An optional automatic XYZ sample stage with auto-focus can be used for sample or mapping analysis of a larger sample area. The addition of a linear array MCT detector provides very high speed mapping and imaging especially useful for dynamic experiments.
The IRT-5100 is a general purpose FTIR microscope with a standard DLATGS detector (liquid nitrogen cooling not required). The IRT-5100 can also be fitted with a second detector. An optional automatic XYZ stage with autofocus is used for mapping analysis and imaging.
The IRT-5200 FTIR microscope includes a mid-band MCT detector (up to two detectors can be installed). IQ Mapping allows multi-point, line, area and ATR mapping experiments without moving the sample stage, in addition to single-point measurements. An optional automatic XYZ stage provides auto-focus and mapping or imaging analysis of larger sample areas.
Spectra Manager™ Suite provides many automated functions with a simplified operation. Measurement conditions, microscope sample monitoring/control operations and measurement results can be reviewed in a single screen. The dedicated microscope interface provides various types of measurements such as single and multiple points, mapping, and linear array measurements using a single mouse-click for mode selection. Real-time monitoring of the spectrum and a calculated functional group image can be specified during mapping measurement.
The ClearView ATR objective provides a simultaneous sample viewing as the ATR prism contacts the sample and during ATR data collection. IQ Mapping enables automated multi-point mapping, line mapping, grid mapping and IR Imaging analysis of a microscopic area with a manual sample stage and a single element detector.
IQ Mapping coupled with a “ClearView” ATR objective allows ATR mapping and ATR Imaging of a sample in contact with the ATR objective without moving the sample stage or ATR objective, while observing the sample area in contact with the crystal prism. IQ Mapping minimizes sample damage and provides high-speed and cross-contaminant free measurements of a relatively small sampling area.
Absorption peaks due to atmospheric water vapor and CO2 can make it difficult to obtain high quality sample spectra. The standard microscope and FTIR optical system includes multi-zone purge to reduce effects of atmospheric gases, but the most effective solution is the measurement of samples in a vacuum. The IRT-5000 series can be configured as a full vacuum FTIR microscope system.
