A look at UV sterilisation and how advances in optical filters for illumination have opened up new applications by alleviating safety concerns
This white paper offers an in-depth look at UV sterilization, including how the latest developments in filter technology have improved the safety of sterilization devices, and presents a number of use cases.
Laser Components is expanding its portfolio of UV LEDs with products from the South Korean manufacturer Photon Wave
Current worldwide conditions have brought a renewed focus on ultraviolet or UV based sterilization systems. UV light has been shown to kill many types of pathogens. A key metric is the dose, or amount of UV light on a surface, as a minimum dosage level is required for effective sterilization. Using optical analysis software as part of the design process ensures that these minimum dosage levels are obtained.

An LED irradiation system has been developed at the Ferdinand-Braun-Institut in Berlin that aims to kill microorganisms with ultra-short wave UV light. The researchers anticipate that the UV light emitted from their device will not be harmful to human skin
With increased interest in using UV light to deactivate viruses, Robert Yeo, director at Pro-lite Technology, discusses the safety and effectiveness of UVC devices
The robots guide themselves around hospital rooms irradiating surfaces with UV light, which disinfects and kills viruses and bacteria.
