For over 50 years, Block Engineering has been a leader in mid-infrared detection instruments. Our industry-leading Quantum Cascade Laser spectrometers and mid-IR laser sources offer the widest tunable range and most rapid chemical analysis on the market today. Block's compact FTIR and QCL modules also offer OEM customers new choices for integration into their own gas sensing and surface analysis products.


Block is pleased to introduce the new LaserSense compact Quantum Cascade Laser-based gas detector. The LaserSense can be used in mudlogging (C1-C5 hydrocarbon gas detection), process monitoring, and endpoint detection applications. The LaserSense features a configurable dynamic range and LOD options with customizable gas cell lengths based on requirements.

Block also recently released two new products for OEM customers: the ultra-compact Mini-QCL Quantum Cascade Laser OEM module, featuring 250 cm-1 per module, and the Mini-FT OEM FTIR module, a compact, rugged FTIR Interferometer / detector module that can be combined with an external infrared source to form a complete spectrometer.

New: Block announces the LaserWarn open-path gas detection system.

The LaserWarn system can detect chemicals in parts-per-billion sensitivities over thousands of square feet. The system can be used to protect personnel against chemical threats and can also be used for industrial leak detection.
