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 fastest chemical analysis on the market today. Block's compact QCL module also offers OEM customers new choices for integration into their own gas sensing and surface analysis products.


Block is pleased to introduce the LaserSense-CV Calorific Value, BTU, and Wobbe Index analyzer for the natural gas industry.

The LaserSense-CV provides accurate speciation of C1-C6+ hydrocarbons (including isomers) in seconds, and requires no consumables. Purged NEMA, explosion-proof, and pelican case housing options are available for the analyzer.

Block also offers the widely tunable LaserTune quantum cascade laser source, featuring a gap-free tuning range of 5.4-12.8 microns. The LaserTune is configurable with up to 4 internal laser modules.


July 6, 2016 — Block MEMS Wins $9.8M Government Contract for Standoff Detection of Chemical Threats.

Block has been awarded a contract from the Intelligence Advanced Research Projects Activity (IARPA) to develop a system that can detect trace quantities of chemicals at standoff distances.

Under this contract, Block will develop a new class of widely tunable, high-pulse energy Quantum Cascade Lasers and also next-generation detection algorithms to detect and identify hundreds of chemicals on a wide range of surfaces.
