ASD range

For more than 25 years, ASD FieldSpec, TerraSpec, and LabSpec spectrometers have set the standard for near-infrared (NIR) spectroscopy analysis in research, exploration, and industrial environments. 

ASD spectrometers and spectroradiometers provide state-of-the-art, real-time performance. Now part of SciAps (a Malvern Panalytical company), these gold-standard systems are backed by world-class engineering, support, and innovation.

Whether you're mapping mineralogy from the sky or drilling into data on the ground, these spectrometers and spectroradiometers offer precise, reliable, and application-ready performance across the entire spectrum of exploration and analysis.

• ASD TerraSpec mineral analyzers provide portable, rapid, and non-destructive analysis of minerals in the lab or the field
• ASD FieldSpec spectroradiometers are designed specifically around the challenges researchers face when collecting spectral measurements in the field
• ASD LabSpec spectrometers (with built-in fiber optic light source) are suitable for applications requiring a spectrophotometer

Key differences at a glance

• Cable design: FieldSpec has a permanently factory-installed fiber optic cable, while TerraSpec and LabSpec use jumper cables with SMA 905 connectors for field repairs and varied setups
• Signal sensitivity: FieldSpec outperforms both TerraSpec and LabSpec, especially in natural light conditions
• Use case: FieldSpec excels in outdoor, high-accuracy conditions; TerraSpec is ideal for mining and rugged fieldwork; LabSpec suits budget-conscious buyers working with artificial light

The mineral exploration process

1. Aerial survey with sensors: Specialized sensors scan large areas for mineral deposits
2. Ground-level confirmation with FieldSpec: Validates and refines aerial survey images
3. Targeted drilling: Uses confirmed data to identify precise drilling locations
4. Material analysis: XRF identifies metals, while NIR pinpoints specific mineral compositions
