Block Introduces LaserBench™ at Pittcon 2012 -The World's First QCL Spectrometer Compatible with FTIR Accessories

publication date: Mar 12, 2012
author/source: Block Engineering
LaserBench SpectrometerBlock Engineering, the leader in Quantum Cascade Laser (QCL) instrumentation, announced today the introduction of the LaserBenchTM Spectrometer, a next generation benchtop QCL spectrometer for the laboratory. LaserBench is styled as a conventional spectrometer with a sample compartment designed to accommodate standard FTIR accessories. In this format, the QCL spectrometer expands the role of infrared spectroscopy for analytical and metrology applications without additional costs to the end-user by leveraging existing accessories currently used in the laboratory.

During the past three decades, FTIR has become the standard for infrared spectroscopy due to its ability to handle a broad range of sample types. Despite this flexibility, many FTIR experiments are limited by throughput and optical performance. LaserBench removes these limitations by providing the advantages of higher spectral power using QCL technology, while also offering flexible sample handling with its use of standard FTIR accessories. LaserBench has a small footprint with a purgeable sample compartment designed to accept center-focus FTIR accessories. Like most FTIR instruments, the accessories are mounted on a pre-aligned base plate that can be readily interchanged on a "plug-and-play" basis.

"Over the past 50 years, I have seen the various evolutions of infrared spectroscopic instrumentation. The option to have a broadly tunable infrared laser-based light source has long been the spectroscopist's dream," said Dr. John Coates, President of Coates-Consulting, LLC. and renowned expert in infrared spectroscopy. "This dream has now become reality and I look forward to being able to meet the challenges of demanding applications."

"The LaserBench Spectrometer is a great engineering accomplishment and demonstrates the versatility and flexibility of our QCL technology," added Dr. Erik Deutsch, Block's Vice President of Engineering. "Such seamless integration with FTIR standard accessories is now opening the door to numerous applications and allows our customers to evaluate their concepts prior to full deployment into field, handheld, or online applications."

The LaserBench Spectrometer provides superior performance for all energy-constrained applications, including micro-sampling, low optical transmission samples, such as carbon-filled polymers and composites, and all forms of reflectance measurements, whether specular, diffuse, or ATR, and for specialized applications that are energy-starved or present challenging optical interfacing, such as fiber-optics. Anticipated applications range from trace contaminants of surfaces to challenging highly absorbing compounds as encountered in several applications, such as heterogeneous catalysis studies.
