Precise Measurement of UV Light Sources for Disinfection
UV radiation encompasses a very wide wavelength spectrum between 10 and 400 nm and is subdivided in ISO Standard 21348 into three ranges. The UVC range between 100 and 280nm is currently extremely relevant for air and water disinfection for combating COVID-19. Since the outbreak of the pandemic this has been manifested, among other things, in a sharp increase in the demand for UVC light sources.

CIE Position Statement on the Use of UV Radiation to Manage the Risk of COVID-19 Transmission
The coronavirus disease (COVID-19) pandemic has accelerated the search for environmental controls to contain or mitigate the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the disease. SARS-CoV-2 is usually transmitted from person to person by contact with large respiratory droplets, either directly or by touching virus-contaminated surfaces (also denoted as fomites) and subsequently touching the eyes, nose or mouth. Importantly, there is growing evidence of virus transmission via the airborne route as the large respiratory droplets dry out and form droplet nuclei which can remain airborne for several hours. Depending on the nature of the surface and environmental factors, fomites can remain infectious for several days (van Doremalen, 2020).
The use of germicidal UV radiation (GUV) is an important environmental intervention which can reduce both contact spread and airborne transmission of infectious agents (like bacteria and viruses). GUV within the UV-C range (200 nm–280 nm), primarily 254 nm, has been used successfully and safely for over 70 years. However, GUV must be knowledgably applied with appropriate attention to dose and safety. Inappropriate GUV application can present human health and safety issues and produce insufficient deactivation of infectious agents. Application in the home is not advisable and GUV should never be used to disinfect the skin, except when clinically justified.

Lumitronix Provides Solutions for Use of UV-C LED Under Real Conditions
As an official distributor of Nichia in Europe, the Hechingen-based LED company Lumitronix offers access to the most powerful UVC LED currently on the market. The NCSU334A emits a wavelength of 280 nm in the ultraviolet range and especially in the UV-C band and enables immediate sterilization and cleaning of air, liquids and surfaces. Bacteria, germs and viruses can be reliably killed in this way. This means that the UV LED from the world's largest LED manufacturer can also act as a possible weapon against the novel corona virus.

Specification and Applications for ProLight Opto's Recently Released UV-C LEDs
Escalation of the Coronavirus outbreak have led to higher demand for Ultra-Violet C (UV-C) LED around the world. UV-C as a germicidal light source can inactivates microorganisms by destroying nucleic acids and disrupting their DNA with its short wavelength. The effective germicidal wavelength is between 200-290 nm; shorter wavelength is more efficient but is also more damaging to the human body. The major chip manufacturers make 265-285 nm as mainstream wavelength, because it can improve single chip's radiometric power and increase in sterilization efficiency.
