LabSpec 4 Hi-Res Analytical Instrument

Superior spectral resolution for sharp feature recognition

  • Spectral resolution of 3 nm in the VNIR range (350 nm-1000 nm)
  • Spectral resolution of 6 nm in the SWIR range (1001 nm-2500 nm)

Product description

Superior spectral resolution for sharp feature recognition

The LabSpec 4 Hi-Res analytical spectrometer is designed for analysis of materials that are characterized by sharp spectral features that may require more resolute spectral data for accurate detection and identification.

The 3 nm VNIR, 6 nm SWIR spectral resolution of the LabSpec 4 Hi-Res analytical instrument provides superior performance across the 350 nm to 2500 nm spectral range. The enhanced spectral resolution in the SWIR range (1001 nm – 2500 nm) is particularly useful for detecting and identifying compounds with narrow spectral features in these longer wavelengths such as soil mineralogy, pharmaceuticals, cosmetics, plastics and petrochemicals.

Spectral data with 6 nm SWIR resolution provides a strong foundation for building accurate chemometric calibration models for quantitative and qualitative materials analysis. The spectrometer configuration delivers superior signal throughput and is compatible with all ASD bifurcated probes and lighted accessories.

The LabSpec 4 Hi-Res i model
Includes an internal broad-spectrum halogen light source that eliminates the need for an external fiber optic light source, which is required for bifurcated probes and some accessories.
