At the beginning of October, 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 devoted entirely to the growth market of UV LEDs. Together with the industry association Advanced UV for Life e.V., Laser Components had developed a program around the short wavelength ranges UVC and Deep UV. UVC applications for disinfection and sterilization are currently among the most important growth drivers in the industry.
Toptica Photonics AG presented a Deep UV high-power laser system that serves as a 229 nm laser source for UV Raman spectroscopy. Other developments by institutes and companies deal, for example, with the production of UVC LEDs, or new coating concepts that incorporate so-called quantum laminates (QNLs) into the layer system. This allows the optical band edge and the refractive index to be adjusted more precisely and the damage threshold resistance to be increased. UVC LEDs are considered a future technology for the disinfection of water, air and surfaces. On the second day, Jens Raß from the Ferdinand Braun Institute informed the participants about the current status in the field of Far UVC.
