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.
Beam Splitters Range subject to coatings
KBr 7,000 to 400 cm-1
ZnSe 5,000 to 500 cm-1
CaF2 10,000 to 1,000 cm-1
Quartz 15,000 to 3,000 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.
