IRsweep has developed a new laser module. Its Laser Module C is the successor to the Laser Model A. According to a press release, it will remain available to ensure full flexibility in beam configuration and the best relative alignment between laser modules. The new Laser Module C is said to be more cost-effective and compact, in addition to being suitable for use with all of the company’s existing spectrometers.
Headquartered in the Greater Zurich Area, IRsweep offers optical spectroscopy solutions and multi-pass absorption cells. The spectroscopy is based on semiconductor quantum cascade laser frequency combs in the mid-infrared wavelength range.
During a webinar on January 10, 2023, Karen Keppler from the Swiss Federal Institute of Technology in Zurich (ETH) will demonstrate how very high spectral resolution is possible without compromising the temporal resolution. She will present the application of an iris spectrometer in connection with pulsed supersonic molecular jets. Registrations for the webinar can be completed online. A corresponding ETH publication has also been made available to view.
The IRsweep publication additionally references a new application demo with Fraunhofer CAP in Glasgow. The Iris core was used to detect traces of explosives. In October, the first demonstration of dual-comb polarimetry in the mid-infrared range was published in the journal “Nature” in cooperation with experts from the Leibniz Institute for Analytical Sciences in Dortmund.
