General

The INTERSPEC series FTIR modules are stable, rugged units requiring the minimum of external utilities.

*The sealed, desiccated enclosure keeps the interferometer dry

*The IR/NIR source does not require water cooling

*The interferometer mechanical bearing does not require a gas supply.

For easy access, those system components which have a finite lifetime (i.e. laser, and radiation source) are located at the front side of the module. A yellow LED indicator indicates, when the scanning is turned on.

Interferometer Performance

The interferometer compartment under cover is 250 x 250 mm wide and 140 mm high. The Interspec 400-X series of instruments employ a sealed and desiccated interferometer, ensuring high spectral integrity with low levels of water vapour within the interferometer. We also offer a version (400-XZ) that employs a ZnSe moisture insensitive optics to be impervious to water vapour and can be used to advantage in serious tropical environment's.

Near infrared version (400-XN) employs a fused silica optics and is insensitive to any influence of water vapour.

Resolution in the infrared is available factory default from 2 cm^-1 to 32 cm^-1 (option 0.5 and 1 cm^-1). The overall wavelength range is 7000 to 400cm^-1 (IR) or 15000 to 3000 cm^-1 (NIR).

Extending Wavelength Ranges

In order to facilitate the use of more than one beam splitter or detector , provision has been made to interchange the beam splitter and detector assemblies allowing the Interspec 400-X to be used at any wavelength from 15000 to 400 cm^-1.

Sample Handling Accessories

Interspec 400-X series instruments may be used as an heart of a more complex spectroscopic system. Sampling handling and the whole system is defined by the customer.
