Hyperspectral imaging sensor

Headwall’s Hyperspec VIS family of integrated hyperspectral imaging sensors for the 380 to 825 nm spectral range claims to provide the foundation for using hyperspectral imaging to achieve superior spectral sensing and chemical imaging.

Hyperspectral imaging is used for mission-critical applications ranging from process monitoring to moving webs of product across conveyor lines to non-invasive medical imaging where precise colour measurement is critical to the application.

The award-winning, imaging spectrometer family is built on a totally reflective concentric, f/2.0 optical design and optimised for imaging in harsh environments. All Hyperspec instruments are based on the company’s aberration-corrected, imaging design which feature the company’s 'original', high efficiency holographic diffraction gratings.

In order to minimise stray light and aberrations, transmissive optical components are not used within the imaging spectrometer. This platform is further enhanced by a telecentric optical input design which enables superior spectral and spatial imaging.

The Hyperspec VIS imaging spectrometer is available in four configurations, each model providing different capabilities to support application requirements such as frame rates, dynamic range, region of interest binning, price, and more.

The Hyperspec VIS sensors are also available with the Hyperspec Starter Kit, the Hyperspec Reflectance/Fluorescence System, and in pan/tilt configurations for stationary deployment.

Applications include:

• Machine vision;
• Moving webs of product;
• Colour measurement;
• Pulp & paper;
• Textile production;
• Food safety & quality;
• Process control of biomass/biofuels;
• Remote sensing & analysis;
• Photovoltaic/semiconductor manufacturing;
• Waste recycling & sorting;
• Non-invasive medical imaging.

Key benefits include:

• Superb imaging performance;
• Exceptional spectral & spatial resolution;
• Ideal for low light, low signal applications;
• Compact with very wide field of view;
• Extremely high signal-to-noise;
• Low scatter or stray light;
• Rugged design for durability & stability.
