FT/IR-8X

The FT/IR-8X is JASCO’s most advanced FTIR spectrometer to date with an excellent signal-to-noise ratio (55,000: 1) and the highest resolution (0.07 cm^-1).

The highly configurable optical system can be customized to virtually any FTIR application, from simple Mid IR measurement to much more complex analysis in the near and far IR. The 8X makes reliable measurements even for the most challenging applications with options such as emission port optics, external detectors, full vacuum, and step scan.

User-exchangeable components combined with full automation make it possible to perform spectral measurements from 25,000 cm^-1 to less than 20 cm^-1 without touching the system.

Multi Detector

User exchangeable beam splitters and windows

Expandable Wavelength Range

The standard spectrometer uses a Ge/KBr beam-splitter with KRS-5 windows and a DLaTGS detector (also with KRS-5 window) for a spectral range of 7,800 to 350 cm^-1. There is a wide range of options to select part or all of the spectral range from 25,000 to 20 cm^-1, including a fully automated beam-splitter and window exchange for unattended operation. With the widest choice of  optical materials, a wide spectral range can be covered using a minimum number of components including a combination  of new broad-band beam splitter, window, and detector materials covering the mid-IR to far-IR

Nitrogen Purge and Evacuation

A multi-zone N₂ purge system is included as standard to minimize the interference from environmental gases and vapors  (CO₂ and H₂0 elimination algorithms are also included).  The interferometer, sample chamber, and detector areas can all be independently evacuated in a full or partial vacuum instrument  (useful for fast sample loading) to completely eliminate CO₂ and H₂0 for the most sensitive sample measurements, and as the moving mirror does not rely on an air-bearing, the vacuum can easily be maintained.

Emission Ports and External Light Measurement and Characterization

The FT/IR-8X has several options for optical ports with a range of window materials for the measurement of external sources of light and black body devices. A collimated beam can be brought out of the instrument for measurement in external sample compartments.

Rapid Scan and Step Scan

Rapid Scan offers a spectral collection of up to 40 Hz. Step scan (option for the FT/IR-8X) coupled with matching high-speed pv-MCT detectors offers two different spectral collection rates at either 1 millisecond (1,000 Hz) or 10 nanoseconds (100 MHz) using Amplitude or Phase modulation and Time-Resolved with photo-acoustic detection.
