IRT-1000 Microscope

The Irtronμ (Irtron Micro) sample compartment microscopy system is designed to provide affordable analysis of microscopic samples with the high performance features of an external FT-IR microscope accessory.


System Description

The Irtronµ offers unprecedented convenience and ease of use, compatible with the JASCO FT/IR-4000 and 6000 series FT-IR instruments. The microscope accessory installs into the spectrometer sample compartment in seconds without optical alignment. The state-of-the-art optical design guarantees high throughput for highly sensitive measurements of samples approaching 20 microns. The Irtronµ can be operated with the integrated touch panel or via a PC using the Spectra Manager™ II software interface. The sample is observed with the integrated color CCD camera and a 5 inch TFT color LCD monitor. JASCO’s unique ATOS (Aperture Through Optical System) provides simultaneous viewing of the sample image and sampling location specified by the aperture.

System Features

  • Can be easily set into the sample compartment within seconds. No optical alignment is required before measurements.
  • Three measurement modes are available including: Transmittance, Reflectance, and ATR analysis.
  • DLATGS detector in FT-IR main instrument (standard)
  • MCT detector or Near IR optimized detector available (optional)
  • Optional sampling accessories for liquid and powder samples
  • Unique sample observation system allows complete view of sample, even during measurements.
  • Data acquisition and processing are performed by the Spectra Manager Software. Spectral data can be stored with a video capture of the sample view.

Options for the IRT-1000



An optional purge casing can be used to eliminate interference from atmospheric CO2 and water vapor bands.

ATR objective

ATR objective

Three types of optional ATR objectives are available, selecting from ZnSe, Ge, and Diamond crystal elements. An optional pressure sensor (recommended) to protect the ATR objective is also available.
