For over 50 years, Block Engineering has been a leader in mid-infrared detection instruments. Its industry-leading Quantum Cascade Laser spectrometers and mid-IR laser sources offer the widest tunable range and most rapid, non-contact surface 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 LaserTune ultra-tunable Quantum Cascade Laser, featuring an industry-leading gap-free tuning range of 5.4 - 13 microns (Δν > 1000 cm-1) configurable with up to 4 internal laser modules. No external power supply or control peripherals are required.

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.
