Max Planck Institute
chooses laser source for microscopy experiments
The Max Planck Institute for Biophysical Chemistry is using Mobius Photonics’ G1R2 laser source in the former’s super-resolution microscopy experiments.
The Mobius G1R2 was
customised for the institute’s needs to produce a comb spectrum of user-selectable visible wavelengths with about a 1ns pulse duration and a 20MHz repetition rate. The institute’s experiments demonstrated that a laser-based fluorescence microscopy technique called stimulated emission depletion microscopy could image intact living multicellular organisms. Mobius technology
vice president Manuel Leonardo said: ‘Building on our experience in super- resolution microscopy Mobius has recently developed a new prototype laser that offers similar capabilities to our G1R2. Called “Rainbow”, the current prototype generates five discrete wavelengths.’ Rainbow produces output at 557nm, 571nm, 585nm, 600nm and 616nm. Like G1R2, it has 1ns pulse durations at repetition rates of up to 20MHz and pulse energies ranging from 25 to over 50nJ per pulse, depending on the wavelength.
telops awarded cooled long wave ir camera contract by Us Navy
Telops has been awarded a contract by the united States’ naval air Systems command (naVaIr) for a cooled, very long wave infrared camera that will be used by the naVaIr Warfare center (naWc) in maryland. Telops’ cooled very long wave infrared camera will be used by the naWc’s Patuxent river Infrared Signature measurements (PrISm) team. The camera has Telops’ patented real-time temperature calibration feature and processed and calibrated images are available instantly from the device. The naWc’s PrISm team work on technologies for the thermal imaging, spectral analysis and tracking of targets, whether they are ships, aircraft or missiles. Telops’ sales and marketing vice president, Paul
chabot said: ‘We are delighted to collaborate with such a world class organisation as naVaIr’s PrISm team. We are proud that our unique infrared camera
the Us Navy EA-18G Growler, which is being developed to replace the Navy’s EA-6B prowler, could be tracked by telops’ camera
will support their efforts to provide the capabilities… for conducting research, development, test and evaluation of naval aircraft, weapons and associated systems.’ Telops has also developed its Hd-Ir 1280 high definition scientific infrared camera, the FaST-Ir 1000 that records at 1,000fps and the Hyper-cam, a lightweight hyperspectral-imaging sensor.
saxony develops glass surface restructuring laser process
a new laser process for structuring large surface areas of float glass has been developed by Laser Zentrum Hannover (LZH) and minden, Germany based-company cerion, which is marketing the process. In a joint research project, LZH and cerion have developed a process that uses an infrared cO2
laser operating at 10.6µm
to restructure the surface of glass. The laser vaporises material on the surface, creating microstructures that alter the

surface’s properties. Large surfaces can be processed, up to 5.4m² per hour. The system uses a mirror to direct the laser across the glass’ surface and only a small change in the mirror’s angle is necessary to cover a large area.
LZH said: ‘Scientists in the
technologies for non-metals department’s glass group adapted a technology used for metal processing to fit the needs of glass production.’ cerion built a prototype and this
was used to optimise the process for industrial use. Testing the mechanical characteristics of the lasered glass, such as its bending and stability qualities, was also part of the process’ development. Patents have been applied for and cerion is offering the technology under the cerilas trademark. The process has already been
used for a building in norderstedt, near Hamburg. nearly 300m² of glass façade was structured on both sides. The façade was made up of glass panels measuring 2.8m by 0.8m. The process’ development
received financial support from the German Federal ministry of economics and Technology.
