New lighting system improves mineral sorting technology

HAIP Solutions, a German technology company, has released a new illumination system designed specifically for short-wave infrared (SWIR) hyperspectral imaging applications, addressing limitations of traditional halogen lighting in industrial environments.

The BlackBright Fast Medium Wave IR features peak spectral response at 1600 nm, optimized for the SWIR wavelength range of 900-1800 nm. The system aims to replace halogen lighting, which typically peaks at 1100 nm and suffers from short lifespans, high heat generation, and excessive energy consumption.

Hyperspectral imaging advances mining operations

Hyperspectral imaging technology has become increasingly valuable in mining and geological research applications. The technology captures detailed spectral information across multiple wavelengths, enabling precise identification of minerals and materials that appear identical to the human eye.

In mining operations, hyperspectral sensors analyze ore composition in real-time during processing, improving sorting efficiency and reducing waste. The technology helps operators identify valuable minerals, detect contaminants, and optimize extraction processes by providing detailed chemical fingerprints of materials.

SWIR wavelengths prove particularly useful for identifying specific minerals including clays, carbonates, and hydroxyl-bearing minerals commonly found in mining environments. These spectral signatures allow automated systems to sort materials with greater accuracy than traditional visual or mechanical methods.

Technical specifications address industrial needs

The new illumination system incorporates a dual-stage reflector design that the manufacturer claims provides energy efficiency and uniform illumination profiles. The modular architecture extends up to 1000 mm in width and fits into existing line-scan systems with a compact 250 mm form factor.

Key technical features include spectral intensity coverage from 900-1800 nm, operational lifetime up to 10,000 hours, and low heat emission for measurement stability. Optional spectral bandpass filters allow users to customize output for specific applications.

The system specifically targets industrial line-scan environments where continuous material analysis occurs, such as conveyor belt sorting operations common in mining facilities.

Growing market for automated sorting

Mining companies increasingly adopt automated sorting technologies to improve efficiency and reduce processing costs. Hyperspectral imaging systems enable real-time analysis of material composition, allowing rapid separation of valuable ore from waste rock.

In geological research, scientists use hyperspectral data to map mineral distributions across large areas and identify potential resource deposits. The technology supports both laboratory analysis of rock samples and field-based surveys using airborne or satellite platforms.

The BlackBright FMWIR represents one of several recent technological advances in SWIR illumination designed to support growing demand for automated material identification in industrial applications.

Traditional halogen lighting systems, while providing broad spectral coverage, face limitations in SWIR applications due to suboptimal peak wavelengths and operational challenges including frequent replacement requirements and thermal management issues.

The new system targets integration with existing hyperspectral cameras and line-scan equipment used in mining sorting applications, where consistent illumination across the SWIR spectrum enables more accurate material identification and separation.
