VIR Series Rugged FTIR Systems

The VIR Series offers a range of versatile and lightweight FTIRs. Including a hermetically sealed interferometer with anti-vibration technologies for demanding laboratory and field applications where a laboratory instrument may be unsuitable.

Portable FT/IRThe VIR series of FTIR systems is compact, lightweight and versatile. The collimated entrance and exit ports make it an ideal instrument for a wide range of customer designed experiments. The standard instrument includes a hermetically sealed interferometer, DLATGS detector, high intensity source, KRS-5 windows and automatic alignment. Options are available for increased sensitivity, optional spectral ranges including NIR, and battery operation.
