Quantum Cascade Laser Products

Block has created IR absorption spectrometers, based on widely tunable (1100 cm-1) Quantum Cascade Lasers. The systems utilize a high brightness QCL source, which results in high spectral power density and radiance. This bright QCL source provides the ability to measure trace and bulk levels of liquids and solids at a standoff distance with high sensitivity and rapidly analyze highly absorbing or diffusive materials.

Block's QCL spectrometers are superior to traditional FTIRs in sensitivity, versatility, ruggedness, and portability. Also, they can very rapidly analyze samples. They are effective for applications ranging from standoff analysis of trace and bulk materials, to gas measurements, to powerful analysis of microscopic targets, such as biological cells or forensic samples.

In addition to its spectrometers, Block also supplies tunable mid-IR sources.

Products include:

  • LaserSense™ is a compact Quantum Cascade Laser-based gas detection system based on infrared absorption spectroscopy. The LaserSense-CV™ is a Calorific Value, BTU, and Wobbe Index analyzer for the natural gas industry. The LaserSense-ML™ is a hydrocarbon analyzer for mudlogging applications.
  • LaserWarn™ is an open-path chemical detection system that identifies chemical leaks and threats at parts-per-billions sensitivity levels from hundreds of meters away. The system detects Chemical Warfare Agents (CWAs) and Toxic Industrial Chemicals (TICs).
  • LaserTune™ is a tunable mid-IR source. The fully integrated LaserTune system has the widest tuning range of any mid-IR QCL source available.
  • MCT IR Detector Module™ is a cooled detector element and preamplifier package optimized for acquiring spectral data with the LaserTune source. The module is also available as a stand-alone detector.
