The VIR series FT-IR spectrometers are designed with flexibility in mind, providing various configurations for the laboratory, the field and customized applications.
For even greater flexibility, external connection optics allows the user to install up to three different attachments in one system, selecting the most appropriate application accessory by simply switching the PC controlled optical configuration. A further extension of application capabilities can be achieved by integrating the universal optical base to configure a freely customized configuration by simply placing optimized optical components and sample holders onto the base. Thus even a large sample or an attachment which cannot fit in a standard sample compartment can now be utilized without compromise.

| Option: | – | Halogen lamp (Auto switching) | High-intensity ceramic source | |
| Rapid scan: | – | 40 Hz (Option) | 40 Hz (Option) | |
Step 2: Selection of accessories
A wide variety of measurement attachments are available.
| Name of attachment | Main application / feature |
| SmartTech attachment | Qualitative measurement of powder and solid samples |
| Fiber interface attachment | Process monitoring |
| Long path gas cell attachment | Quantification of gas/vapor samples |
| Single reflectance ATR attachment | Analysis of powder, solid and liquid samples |
| NIR Specular reflectance attachment | Non-destructive measurement of coatings and reflective samples |
| IRT-1000 micro IR attachment | Micro-samples and contaminants |
| Autosampler attachment | High throughput analysis of drugs, etc. |
| Transmission measurement attachment | Qualitative / quantitative analysis of film samples |
| MultiChambIR attachment | Three measurement modes (Transmittance/reflectance, diff use reflectance and ATR) in one attachment |
The unique MultiChamberIR attachment allows a user to select among three measurement modes from transmittance, ATR and DRIFTS in one attachment. Such multi-measurement modes in one attachment are best suited to incoming inspection of a wide variety of samples ranging from solids to powders to liquids for qualitative and quantitative applications.
Combination with MultiChambIR attachment
Furthermore, the Universal optical base allows a user to configure freely customized optics by simply putting mirrors and sample holders onto the bench.
