Laser Chem micro-electromechanical system

Block is developing an IR Absorption Laser spectrometer using widely tunable Quantum Cascade Lasers (QCL) in the 7-12 ?m spectral range. This unique spectrometer promises to be small, low cost and capable of detecting gases in parts per trillion concentrations.Due to its high laser power and high optical resolution (better than 0.5 cm-1), extreme detection sensitivity can be achieved with a small size sensor. The wide tuning range will enable the use of very few QCL chips (the highest cost component) to achieve a lower cost device. LaserChem" is also capable of active standoff detection in conjunction with a suitable reflecting surface.A lab testing prototype will be available in the fall of 2008 and a commercial product is expected in 2010.For additional information about the LaserChem", please contact
