Image of beam size vs clear aperture

For system setups, it is important to understand the design of laser beam systems that utilize beam steering technology.  More specifically, pairing a beam steering set with a laser is crucial.  During set up, aligning the clear aperture of the beam steering set with the beam size of the laser is critical.  This often raises the question between beam size and clear aperture.

Laser Quantum has provided an article to help you relate the beam size and clear aperture.

The Ariane6 space launcher program successfully completed an important milestone of its qualification plan. A long-duration,​​ hot-fire test on the launch pad at Europe’s Spaceport​​ in​​ French Guiana was performed recently.

ID Quantique‘s contribution​​ to the program is the development and supply of a high performance and OTDR-based (Optical Time-Domain Reflectometer) integrity and performance monitoring system for the fiber optic network of all Ariane6 launchers. The IDQ test equipment​​ is​​ used during the assembly of the launchers as well as on the launch pad prior to each launch.

How Do Optical Tweezers Work?

Watch this video to learn how optical tweezers use light to manipulate matter. See some of the amazing applications for this Nobel Prize-winning technology.

This video was produced by The Action Lab. The Action Lab is a channel dedicated to performing​​ intriguing​​ experiments and answering questions you never thought to ask!

Watch an interview with Dr. David Warshaw, Professor and Chair of Molecular Physiology and Biophysics at the University of Vermont (UVM). His​​ lab works with the protein myosin. In the interview he tells the story about how he started working with Chroma back in 1991!​​ 

His group designed and constructed their own optical tweezers (laser trap) equipment. Integral to this device are custom-designed optical filters that he convinced​​ Chroma​​ to manufacture for his project. He explains​​ Chroma’s willingness to undertake this project and the close relationship he has maintained with Chroma since 1991.

Cameras & Imaging

Learn about an application of the GE-VAC In-Vacuum Camera produced by greateyes in a recent study published​​ recently. The article describing this study is entitled “Laboratory-Based Correlative Soft X-ray and Fluorescence Microscopy in an Integrated Setup.”

greateyes offers a series of high-performance, cooled, full-frame, CCD scientific cameras for imaging and spectroscopy in the range of X-ray to near-infrared (NIR). The cameras combine scientific, highly sensitive CCD sensors and ultra-low noise electronics for optimal detection of weak signals and measurements with high dynamic range. They can be used as detectors for a broad range of​​ applications​​ common in the industrial and scientific community.

LTB Lasertechnik Berlin GmbH​​ announces an exciting new partnership with IL Photonics BSD Ltd in Israel. This collaboration will enable LTB to expand its presence in Israel, a country with a thriving research community and strong​​ photonics​​ industry, and provide customers with enhanced access to​​ LTB’s innovative product portfolio.

Overall, this​​ partnership​​ showcases LTB​​ Lasertechnik Berlin's reliable and accurate solutions for plasma spectroscopy and​​ LIBS​​ technology by providing top-of-the-line​​ technological solutions​​ for demanding research and​​ industrial applications. LTB looks​​ forward to a successful collaboration with IL Photonics in Israel and are excited about the significant benefits this partnership will bring to both companies and of course customers in the region.

LTB Lasertechnik Berlin is thrilled that their ARYELLE spectrometer has taken part in an observation mission related to the OSIRIS-REx. The​​ NASA-led Hypervelocity OSIRIS-REx Reentry Imaging & Spectroscopy (HORIS)​​ project observed the capsule, which contains material of the asteroid Bennu,​​ during the re-entry into​​ the earth’s​​ atmosphere. This project runs in cooperation with the Japan Aerospace Exploration Agency (JAXA), University of Stuttgart, University of Southern Queensland, and University of Queensland.
