Substrate in Prototyp Serie - Aluminiumnitrid für die Forschung und Entwicklung
Aluminiumnitrid ist ein vielversprechendes Material für moderne Anwendungen in der Mikro- und Optoelektronik. Voraussetzung für die Entwicklung von AlN-basierten Technologien ist die Verfügbarkeit von Substraten mit definierten und reproduzierbaren Eigenschaften – eine Lücke, die durch das IKZ geschlossen wird.

Arrays of ultraviolet micro-LEDs for production, sensing, and communication
Red, green, and blue light-emitting diodes (LEDs) with diameters below 100 µm are already widely used, e.g., in display applications. Recently, researchers at the Ferdinand-Braun-Institut (FBH) in Berlin have extended the wavelength range into the ultraviolet (UV) spectrum. This opens up novel applications for these devices, such as in rapid prototyping, mask-free photo lithography, sensing, and non-line-of-sight communication.

UV experts from all over the world exchanged ideas - 3rd International UV WORKshop
LASER COMPONENTS Press Release | 11.10.2022
On October 5 and 6, around 45 representatives from industry and research met at LASER COMPONENTS in Olching near Munich for the 3rd International UV WORKshop. For two days, they exchanged information about the latest developments in the field of ultraviolet light. The second day of the event was dedicated entirely to the growth market of UV LEDs. Together with the industry association Advanced UV for Life e.V., LASER COMPONENTS had developed a programme around the short wavelength ranges UVC and Deep UV. UVC applications for disinfection and sterilisation are currently among the most important innovation drivers in the industry.
FBH to showcase advanced diode lasers and UV LEDs at Laser World of Photonics – from chips to prototypes
The Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) will present its full range of capabilities at Laser World of Photonics in Munich from April 26-29, 2022 – from design and chips to modules and systems. At the Berlin-Brandenburg joint booth B5.528, the institute will be exhibiting, among other things, an irradiation system with optimized 233 nm far-UVC LEDs. Such systems are used in medical applications to inactivate multi-resistant pathogens and corona viruses directly on the skin.

Nature paper published on bactericidal efficacy and skin tolerance of a UVC LED irradiation system
The paper "Application of 233 nm far-UVC LEDs for eradication of MRSA and MSSA and risk assessment on skin models" published in 'Scientific Reports' (nature) describes the successful test of bactericidal efficacy and skin tolerance of a UVC LED irradiation system with an emission wavelength of 233 nm developed at FBH. At an irradiation dose of 40 mJ/cm2, the concentration of multi-resistant pathogens (including MRSA and MSSA) on the skin was reduced by five orders of magnitude.

Shorter Development Times for Applications with SiC UV Photodiodes
The JTIA1-1G transimpedance amplifier from ifw optronics amplifies the photocurrents generated by SiC UV photodiodes, which are only a few nanoamperes strong, and converts them into a usable voltage level. The user can select from three preconfigured resistance values via jumpers.
The component, which is available from LASER COMPONENTS, is particularly user friendly. Photodiodes in TO5 or TO18 housings can be connected directly to the board.

More than drying: Infrared heat and UV technology improve coating quality and speed
Infrared heat dries, UV light cures - sounds simple. However, substrate, coating and production line often have very specific requirements for drying and curing. It's good when UV systems or infrared ovens can be precisely adapted. It's good when UV systems or infrared ovens can be precisely adapted. It is worth putting the dryers used up to now to the test, as the example of a British manufacturer of goal posts shows. With modern, precisely controllable infrared systems, drying can now be three to four times faster.

Successfully Killing Airborne Viruses and Bacteria
UVC LEDs from the US manufacturer Bolb achieve a 99.95% kill rate for airborne viruses and bacteria. This has been confirmed by the Guangzhou Institute of Microbiology.
The tests were conducted, among other viruses and bacteria, on aerosolized multidrug-resistant Staphylococcus aureus (MRSA). In a closed air-disinfection reference design, the researchers used a Bolb UVC LED light module with an electrical input power of 40 W and a UVC output power of 2.5 W. At a flow rate of up to 3,000 liters per minute, this air disinfection device achieved an inactivation rate of 99.95%

Higher Level of Disinfection in Less Time
The UVC-LED S6060TL from Bolb is highly efficient in the disinfection of water, air, and surfaces. The narrow beam angle of only 33° guarantees a high intensity of UVC radiation. This allows a shorter irradiation time and thus also more efficiency in disinfection.
